[英]Error when setting up virtualenv with Python 3
I'm attempting to create a virtualenv (using virtualenvwrapper) with Python 3 as my default interpreter, but keep receiving the same error after un/reinstalling Python 3, virtualenv, and virtualenvwrapper several times. 我正在尝试使用Python 3作为我的默认解释器创建virtualenv(使用virtualenvwrapper),但是在多次重新安装Python 3,virtualenv和virtualenvwrapper之后仍然会收到相同的错误。
$ mkvirtualenv -p /usr/local/bin/python3 test-env
Running virtualenv with interpreter /usr/local/bin/python3
Traceback (most recent call last):
File "/Library/Python/2.7/site-packages/virtualenv.py", line 23, in <module>
import subprocess

I have both Python 2 (prepackaged version for OS X) and Python 3 (via brew install python3
) installed. 我安装了Python 2(OS X的预打包版本)和Python 3(通过
brew install python3
)。
I can create virtualenvs fine using any of my Python 2 binaries. 我可以使用我的任何Python 2二进制文件创建virtualenvs。
I had the exact same error, and in my case I was able to solve it with the following steps: 我有完全相同的错误,在我的情况下,我能够通过以下步骤解决它:
$ brew unlink python3
$ brew link --overwrite python3
$ unset PYTHONPATH
After that, virtualenv
worked as expected. 在此之后,
virtualenv
按预期工作。
