I'm using my company's VM which already has Python 2.7 (comes with the OS) and Python 3.6.13 (Installed by the company)
Recently, there is a need to upgrade an application to latest version of Python ie: 3.10.2
So, I installed Python 3.10.2 in a local directory inside my $HOME. I referred to this link for the installation link.
While 2.7 & 3.6 are already there in the system.
Now, when I try to create a VENV with this python version (3.10.2), I see this error:
Traceback (most recent call last):
File "/export/home/sdc/python_versions/python310/python/lib/python3.10/subprocess.py", line 69, in <module>
import msvcrt
ModuleNotFoundError: No module named 'msvcrt'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

I found some solutions like this one: link but I cannot figure out how it will translate in my case since my installation directory is not /usr/local/... It is $HOME/path/to/dir
Python on Linux does not have the msvcrt module at all. It's strictly Windows only. You seem to have miscompiled your Python somehow, since it also doesn't have the _posixsubprocess module (and msvcrt is used for Windows detection in subprocess.py).
May I recommend using pyenv or asdf for custom Python versions? They're less likely to miscompile Python.

I have python and pip installed on the machine.
It looks like this may be a version compatibility issue with Python 3.11. I recommend upgrading to the latest version of Python and then running the command again.
This is why you are getting this error.

My QGIS python console returns error

I installed the python module to OS through pip but it is not available to QGIS python console. A previous question suggests it should have worked: Installing the Python geojson module on Mac OS X Yosemite to use with QGIS
I have the following error message on windows 64-bit and Python 2.7.

i used this module several times (it's a core module of my work), but today i have this problem. I unistalled liblas, reinstalled, unistalled all Python and all modules, and reinstall everything bit i have always the same problem.
If you have 64-bit version of Python installed and LibLAS dll 32-bit, then you can get this type of error. If so, then you can find 64-bit version of this library on this site (there are actually a lot of other 32-bit and 64-bit libraries for Python).
I've been using buildout for quite a while now without any issue, in fact I did yesterday without any problems.
But as today all my projects fail to buildout. I tried on two different Ubuntu workstations with the same result.
This is the error I get:

Original exception was:

It complains that there's no module named apport.fileutils .. but I get no exception when I run python and import it:
from apport.fileutils import likely_packaged, get_recent_crashes
2.0.0 just got released. The old bootstrap.py is not compatible with 2.0.0 but downloads it by default. You can get the v2 bootstrap.py from here, or use the code below if you want to stick with the old version.
python bootstrap.py -v 1.7.0
edit: older versions of v1 bootstrap.py don't allow version forcing. The up-to-date version here does.
The question + answer is from 2013. I recently (2015) saw it happening again.
The problem is that ubuntu's python-apport package installs a /usr/lib/python2.7/dist-packages/apport_python_hook.py file that overrides sys.excepthook. It makes sure python tracebacks are fed into ubuntu's "apport" error reporting mechanism.
That in itself is not a problem. But bootstrap.py restricts the python path, so that the hook cannot import apport anymore...
So if an error occurs during the bootstrap run, an exception is printed which then fails a second time because apport cannot be imported.
A solution could be to sudo apt-get remove python-apport. That's at least what we did on the server (where having apport makes no sense in any case).
