Cannot install module - /bin/pip: No such file or directory

[nzagorchev]

Hello,

Trying to install a module fails with the following error:
/bin/sh: /bin/pip: No such file or directory

I am using MacOS and have installed python and python3 using homebrew.
Then installed pipenv using pip3.

which pip returns:
/usr/local/bin/pip
and pip itself is found as a command.

However, if I use python -m pip --version it points to the default MacOS python:
pip 9.0.1 from /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)

I am unaware where it tries to resolve pip from and does not find it.
I am not sure if there is a problem with my $PATH paths or the issue is different.

Thank you for your time!

Try the fancy installation method

Second. Pipsi is the way to go for installing python cli utils

[nzagorchev]

Thanks for the replies.

I first uninstalled and installed again python and python3 using homebrew and also re-installed pip.
Then I was able to successfully install pipenv using pipsi by the provided link for the fancy installation.

However, trying to install any module, I know get the following error:
Traceback (most recent call last):
File "/usr/local/bin/pipenv", line 7, in
from pipenv import cli
File "/usr/local/lib/python3.6/site-packages/pipenv/init.py", line 13, in
from .cli import cli
File "/usr/local/lib/python3.6/site-packages/pipenv/cli.py", line 11, in
import background
ModuleNotFoundError: No module named 'background'

[nzagorchev]

Using pip3 I installed background and semver.

Now I am facing another issue:
ModuleNotFoundError: No module named 'piptools'
$ pip3 install piptools
Collecting piptools
Could not find a version that satisfies the requirement piptools (from versions: )
No matching distribution found for piptools

I believe there might be a root cause of the above since I am not sure if all those errors are expected.
Your help is much appreciated.

[nzagorchev]

Typo in the pip-tools. Installed them and now I am back at square one with the initial error:
/bin/sh: /bin/pip: No such file or directory

[kennethreitz]

Do you have PYTHONHOME set or something?

[nzagorchev]

No, I do not.

pip is available in terminal.
$ which pip
/usr/local/bin/pip

but it is only 'attached' to python2 and python3 but not the default python:
$ python -m pip
/usr/bin/python: No module named pip

Any ideas on what could be wrong?

[nzagorchev]

Seems the root cause was that pew was not working due to not set locale.
Setting it in .bash_profile seems to resolve the issue.

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

Will further test and later update if this is solved.

[kennethreitz]

We should check for this and add some pretty error message if it's not set.

[erinxocon]

@kennethreitz should pew check for this or should pipenv?

[kennethreitz]

@erinxocon pew should.

$ hash -r
Reset your bash cache. It will solve the problem.

I was having an issue only on codebuild, and this solved it for me: #1929

[trinanda]

Maybe this will help newbies like me in the future.
I Following @nzagorchev comment:

add @nzagorchev script in your ~/.bash_profile or ~/.zshrc

sudo vim ~/.bash_profile
or
sudo vim ~/.zshrc if you're using zsh

then add the following script to the file

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

then run this command:

source ~/.bash_profile
or
source ~/.zshrc if you're using zsh

then close your terminal and open it again.

after that, it works perfectly :)

$which pip
