@tobiasherp |
Right, PyPI uses https now, so you need ssl support. If your system Python doesn't have it, your virtualenv won't have it either. With Python 3, you should be able to import an

It might not be a venv problem but it is still a problem. In my instance I cannot install in venv or system pip I have seen this: [(https://software.intel.com/en-us/forums/intel-distribution-for-python/topic/737878#comment-1920719)] But I could not fix my version of this problem. Any advice on this issue would be very helpfull |
@theCJMan are you still experiencing this problem? |
I have up on that problem

Transport Layer Security, or TLS, is part of how we make sure connections between your computer and PyPI are private and secure. It's a cryptographic protocol that's had several versions over time. You need to be connecting to PyPI with a TLS support library, such as a recent version of OpenSSL. The specific steps you need to take will depend on your operating system version, where your installation of Python originated (python.org, your OS vendor, or an intermediate distributor), and the installed versions of Python, |
I also experienced this on macos, python 2.7.15 - system python worked fine, virtual env failed to install due to
my system python imported ssl fine, but the venv python gave the following error:
after deleting the env directory, and recreating the env, it all worked fine. |
I got same issue as @liurui39660 , also using Intel Python Distribution and
Note that the bug only triggered when using Intel Python inside a venv. When using the base env, it works:

I had the same issue. I was configuring a new computer with python and jupyter with anaconda, and the problem occured when I tried to install a package use pip. Based on the discussions above, that this is an environment issue, I tried running "pip install" command in Anaconda Prompt instead of cmd. And the pip command was executed. 😁 |
I am still struggling with following since yesterday, after installing Python 3.7.1 with Anaconda3 pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available. |
I had the same problem. Using willliu1995 suggestion solved the problem. Running pip from cmd prompt did nor work but launching jupyter notebook and running !pip install worked. |
If pip install pandas is not working on CMD prompt, run this using Anaconda prompt - it works. You can find Anaconda prompt using this: Go with the mouse to the Windows Icon (lower left) and start typing "Anaconda". There should show up some matching entries. Select "Anaconda Prompt". A new command window, named "Anaconda Prompt" will open. Source - https://stackoverflow.com/questions/47914980/how-to-access-anaconda-command-prompt-in-windows-10-64-bit |
If you prefer to use the Windows Command Prompt instead, you will need to add the following directories to your Windows Environment path: For example, I have my Miniconda installed at |
@shriprem Thanks! It worked. Your solution confirms that this is a system path issue, since generally it's only necessary to add %Miniconda3_DIR%\Scripts to your PATH variable to use pip. Any idea why this has changed? |
@EthanBackToLife I checked the PATH environment variable in the Anaconda prompt, and found that Anaconda was prefixing all those directories to its prompt PATH variable. So I appended the delta part of that path to the Windows PATH variable to confirm that it worked for pip. While trying to install Conda on a different PC, I am able to refine the path changes to a much shorter: With this narrowing down of the path, we can look at the |
Can't install any package via `pip` on windows 10, ssl module in Python is not available pypa/virtualenv#1139
I met the same question as you,and I tried to use the command .\activate ,then settled the question perfectly,I couldn't thank you anymore. |
Great explanation! Thank you. |
I still have this problem after doing what @shriprem commented. Python version 3.7.1 and pip version 18.1, if that helps. |
" I can solve this problem by adding dir path of intel-python which has libeay32.dll (in my case ..\IntelPython3\pkgs\openssl-1.0.2l-vc14_intel_0\Library\bin) in system environment as top most position." reference: https://software.intel.com/en-us/forums/intel-distribution-for-python/topic/737878 |
I've found being in the "Scripts" directory is required to use pip |
For Windows 10 If pip install is not working on CMD prompt, run it using Anaconda prompt - it works. If you want use pip in normal CMD, not only in Anaconda prompt. most people only add D:\Anaconda3\Scripts; |
Specify path C:\Anaconda3\Library\bin in environment user variables. |
I believe the paths are added correctly, but pip is still not working, either on CMD or on Anaconda prompt. |
did you try from the "Scripts" directory? |
If you mean cd xxx/Scripts and then pip install, I tried just now and it's not working. |
Alternative solution: I just managed to make it work by creating a pip.ini file under C:\Users\my_user_name\pip, writing: [global] It solves the problem for the moment, however the download speed using this mirror is not really fast (around 800kb/s). Is there a way to make it work as usual? |

SSL libraries are in your C:\anaconda\Library\bin folder. You have to have that path set at the moment of trying to install your libraries. This is because, when you activate a virtual environment, the PATH is changed. Therefore,
Note that C:\anaconda\Library\bin is consistent in both cases, regardless if you are working in a vm or not. |
@datatravelgit Hi, I am not using virtual environments and there is still this problem after setting path manually. |
Thanks for the helpful comments above! Adding the following to the path variable worked for me on Windows 10: |

I had to replace the libssl-1_1-x64.dll in my envs/myenv/Library/bin folder with the base env dll. It was not the same one. Plus I had another libssl-1_1-x64.dll under C:/Windows/System32/ and under certain Intel folders in C:/Program Files. I removed the Intel stuff from the path and deleted the one under system32. Not sure when the corrupt dll has been copied, but replacing it with the one from conda/Library/bin/ worked well. To further check errors, you could activate your environment and type |
Im experiencing same issue- "The specified procedure could not be found." - only in specifc env. Tried replacing env's libssl-1_1-x64.dll with the base env's libssl-1_1-x64.dll - but didnt help. |
Fixed for me, thanks for everyone's comments.
Removing both libssl-1_1-x64.dll and libcrypto-1_1-x64.dll in C:/Windows/System32/ fixed the problem for me. |
I love you buddy! |

this problem can be solved by changing the path through this pc |
Funny thing: I had the same problem on Android, Termux. Pip could not connect to pypi.org due to absent ssl. |
For Anaconda/Miniconda users on Windows, this is a library load issue. There's information in the troubleshooting FAQ at https://conda.io/projects/conda/en/latest/user-guide/troubleshooting.html#condahttperror-http-000-connection-failed As some users have noted, other installations of openssl into the Windows\System32 folder can be exceptionally troublesome. There's information about a workaround in Anaconda's (and conda-forge's) python in this related troubleshooting section: https://conda.io/projects/conda/en/latest/user-guide/troubleshooting.html#numpy-mkl-library-load-failed You can report anaconda issues at https://github.com/continuumio/anaconda-issues |
I had a recurrence of the SSL issue with pip module installs. Before this, pip had worked fine for several months -- after correctly configuring the environment path to include the 3 conda folders: After a couple of hours of wrangling, I arrived at these two solutions -- one for module installs via pip, and the other for those via conda. Module installs via pipBasically, based on the error messages, I had to add pypi.org and files.pythonhosted.org sites as trusted hosts. You could do this once via: [If you are not comfortable with the 'global' setting change, you could repeat this during every module install. Module installs via condaSome Python modules like basemap don't install via pip. I had to use conda instead. [After the conda module install, I turned the ssl back on with: While resolving these issues today, the general info at https://conda.io/projects/conda/en/latest/user-guide/troubleshooting.html#ssl-connection-errors and the specific sites info from the install-time error messages -- both proved helpful. |
Hi when in the anaconda prompt i am unable to use pip due to TSL/SSL issues:
But i am able to pip install anything I want when using python native:
What I've done so far:
CMD Prompt Locations in native Python:
Anaconda Prompt locations:
Not sure if this matters but OPENSSL_CONF C:\OpenSSL-Win64\bin\openssl.cfg appears above PATH in my system variables. Could someone please help I am not sure how to solve this and would really prefer using Anaconda/Spyder instead of native python |
@jmhcodes, check out this link: https://stackoverflow.com/questions/41328451/ssl-module-in-python-is-not-available-when-installing-package-with-pip3 Also on stackoverflow, I came across another discussion that was more relevant to the sudden recurrence of the SSL certificate verify error that I started facing on my work PC. The discussion link is: https://stackoverflow.com/questions/25981703/pip-install-fails-with-connection-error-ssl-certificate-verify-failed-certi In a couple of those answers, there were these statements:
and
So in my case, it was the corporate network firewall that broke my pip. But adding Honestly, I hadn't seen the 2nd stackoverflow discussion when I had resolved the issue last week, and posted my solution steps here. A majority of responses in the stackoverflow article agree that using |
I've seen these two posts as well and I could add it as a global trusted host and walk away but I am not comfortable enough to do so. What I am really aiming to answer is why pip works without SSL/TSL issues within the native python package in the cmd line BUT does not work in the anaconda prompt even though openssl/libssl-1_1-x64.dll/libcrypto-1_1-x64.dll all point to the same location. |
@jmhcodes, run the command Here are some of the differences that the Anaconda prompt brings to its environment over the regular command prompt:
Note: %CONDA_DIR% should be substituted with your Anaconda install path.
These differences between the two environments could be causing whatever issues you are having. It is up to you to dig further. But if pip.exe is pointing to the same binary from both environments, you shouldn't be very much concerned about which environment you are using to run pip. Also, I wouldn't be too concerned about adding the very well known python.org pip sites as trusted hosts. So were many at stackoverflow. That's my two cents. Lastly, you mentioned:
That's because the system variable OPENSSL_CONF comes before PATH when being listed in the alphabetical order. So it shouldn't matter for the issue you are having. Or did I misinterpret what you were saying? |
