Hi @AnakinSamB , I see that you have a quite old version of pyrevit, can you please upgrade it and check if the issue persist?
I've fixed some (but not all) of the problems of cpython in version 4.8 15.
Hopefully we'll have a working cpython environment for pyRevit 5 release!

[AnakinSamB]

Hi @sanzoghenzo, thanks for the quick reply, unfortunately that did not solve the problem :/. If there is no quick solution i can also wait for the latest version to be released and if that does not fix the error, i will report back here.

[sanzoghenzo]

Is the error the same?
Also, do you confirm that the sample code you posted raises the same error? I ask because the error messages says that the error is at line 7, but the sample code has 4 lines... could it be that you're importing something else before printing?

[AnakinSamB]

I tried something else before posting the bug but it did not resolve the issue, thats why the error message says line 7... sorry for the confusion -> the sample code creates the same error

[sanzoghenzo]

Do you have any lib folder in that extension, or other loaded extensions?

Can you please try to unload all your extension, enable the pyRevitDevTools (from the Extensions manager) and then run the "Engine Tests" -> "Test CPython Command" or "Test CPython Search paths"?

[AnakinSamB]

Good Afternoon,

the error code when i start Text Cpython Command:

when i start Text Cpython Search paths:

[AnakinSamB]

i forgot to mention that i could not find any lib folder either in the current custom extension or any other custom extension

[sanzoghenzo]

I honestly don't know what's going on...

Not sure if it's related, but one thing I see from the pyrevit env output you posted is that under the "running Revit instances" you have the following:

PID: 8216 | 2021.1.6 | Version: 21.1.60.25 | Build: 20220123_1515(x64) | Language: 0 | Path: ""

But that version is not listed in the "Installed Revits".
Does it say the same thing also with the new pyrevit version?

@jmcouffin have you seen something like this before?

[AnakinSamB]

yes it does, i could try to change it, but i would need help

[jmcouffin]

yes it does, i could try to change it, but i would need help

please copy paste the whole pyrevit env report, not just bits and pieces

@jmcouffin have you seen something like this before?

yes, but my install of python 3.8 is a bit of a mess, so this is not entirely relevant.

• I manage to get the proper engine
• I manage to print stuffs
• I cannot use numpy, but I am pretty sure this is I have it not properly installed or that the version is too recent, therefore incompatible with 3.8

[sanzoghenzo]

@jmcouffin have you seen something like this before?

yes, but my install of python 3.8 is a bit of a mess, so this is not entirely relevant.

I was referring to the fact that the running revit instance states version "2021.1.6", which is not in the "Installed Revits"...

It may be totally unrelated to the issue, though...

[jmcouffin]

I was referring to the fact that the running revit instance states version "2021.1.6", which is not in the "Installed Revits"...

to my knowledge it is unrelated.
