Question

我正在使用Python中的virtualenv。

virtualenv _env之后我得到了：

Running virtualenv with interpreter /usr/bin/python2
New python executable in /home/marcin/Documents/Projects/django_tutorial/_env/bin/python2
Also creating executable in /home/marcin/Documents/Projects/django_tutorial/_env/bin/python
Installing setuptools, pkg_resources, pip, wheel...
  Complete output from command /home/marcin/Documen...ial/_env/bin/python2 - setuptools pkg_resources pip wheel:

我有：

virtualenv 15.1.0

pip 9.0.1

Python 2.7.13

我没有想法。我尝试导出语言环境，重新安装pip，setuptools和virtualenv。你有什么建议吗？我将不胜感激。

如果您在中国，则可以更改pip的来源以解决此问题。

mkdir ~/.pip
echo '[global]' > ~/.pip/pip.conf
echo 'index-url = https://pypi.tuna.tsinghua.edu.cn/simple' >> ~/.pip/pip.conf

通过使用清华大学的镜子，您可以解决您的问题。
