Python3.8 venv 返回退出状态 101 [英] Python3.8 venv returned exit status 101

问题描述

我发现了类似的帖子，主要与 venv 上的 linux 相关，但工作有问题.

此后它工作正常:

PS C:\Utilities\PythonBase\Python38>.\python -m venv c:\temp\venv-py38PS C:\Utilities\PythonBase\Python38>

当然，您必须检查并修复您一直在使用的任何 venv，但如果您的情况与我相同，它们无论如何都不会工作.

I found similar posts, mostly related to linux on venv having an issue with working. python 3.8 venv missing activate command However, I am confused on how to solve it on windows, and what is happening.

I installed python3.8 from downloading it on pythons website. Then I follow the 3.8 documentation https://docs.python.org/3/library/venv.html which shows:

python3 -m venv /path/to/new/virtual/environment

I do this but then get the following error:

Error: Command '['E:\\py_envs\\hf4\\Scripts\\python.exe', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 101.

When I use: python -m venv --without-pip hf4

and then hf4\Scripts\activate

It works for activation. What I don't understand is that I can then run pip and it is there during the activated environment. It seems a maybe related issue, is that anything I have installed on my system python is also available. For example, in the activated session:

(hf4) E:\py_envs>where pip
C:\Users\local user\AppData\Local\Programs\Python\Python38\Scripts\pip.exe

One question is naturally how to fix this, the other is that I would appreciate an explanation as to what is happening to better understand it. Does it search first for the active environment, and if it can't find it, defaults to a system version?

解决方案

I had the same problem (with both Python 3.7 and 3.8), I believe it was due to a Windows update when I enrolled in the Windows Insiders program, but that could have just been a coincidence.

PS C:\Users\Your Name\AppData\Local\Programs\Python\Python38> ./python -m venv c:\TEMP\py38-venv
Error: Command '['c:\\TEMP\\py38-venv\\Scripts\\python.exe', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 101.

This worked around the problem in my case:

• Uninstall Python.
• Install with the Custom option.
• Use the "Install for all users".

After this it worked fine:

PS C:\Utilities\PythonBase\Python38> .\python -m venv c:\temp\venv-py38
PS C:\Utilities\PythonBase\Python38>

Of course you'll have to go through and fix any venvs you've been using, but if you're in the same situation as me they won't have been working anyway.
