python - pyvenv 返回非零退出状态 1(在安装 pip 阶段期间)

Question

如果您在使用 pyvenv 命令创建 Python 虚拟环境时遇到以下错误:

user$ pyvenv my_venv_dir
Error: Command '['/home/user/my_venv_dir/bin/python', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1

...然后答案(下面)提供了一个简单的方法来解决它，无需求助于 setuptools 及其相关的技巧。

Answer 1

这是一种与 O/S 完全无关的方法...

pyvenv 和 python 命令本身都包含一个 --without-pip 选项，可以让您解决这个问题；无需求助于 setuptool 或其他令人头疼的问题。记下我在下面的内联注释，这里是如何做的，而且很容易理解:

user$ pyvenv --without-pip ./pyvenv.d          # Create virtual environment this way;
user$ python -m venv --without-pip ./pyvenv.d  # --OR-- this newer way. Both work.

user$ source ./pyvenv.d/bin/activate  # Now activate this new virtual environment.
(pyvenv.d) user$

# Within it, invoke this well-known script to manually install pip(1) into /pyvenv.d:
(pyvenv.d) user$ curl https://bootstrap.pypa.io/get-pip.py | python

(pyvenv.d) user$ deactivate           # Next, reactivate this virtual environment,
user$ source ./pyvenv.d/bin/activate  # which will now include the pip(1) command.
(pyvenv.d) user$

(pyvenv.d) user$ which pip            # Verify that pip(1) is indeed present.
/path/to/pyvenv.d/bin/pip

(pyvenv.d) user$ pip install --upgrade pip # And finally, upgrade pip(1) itself;
(pyvenv.d) user$                           # although it will likely be the
                                           # latest version already.
# And that's it!
