Mac 在 Azure 云平台中设置 Django 时出现 Virtualenv 错误

Question

我在这里找到了教程： https://azure.microsoft.com/en-us/documentation/articles/web-sites-python-create-deploy-django-app/

我正在尝试创建一个 Django 项目并将其与 Github 和 azure 云平台同步。至于先决条件，除了 Python 之外，我什么都有 Visual Studio 的工具，因为我使用 PyCharm 进行开发。

我按照教程的指示克隆了存储库，但是当我尝试创建虚拟环境时

$python -m virtualenv env

我收到以下回复：

我正在使用随 anaconda 软件包一起安装的 Python 2.7。我使用以下方法安装了 virtualenv：

conda install virtualenv

提前致谢！

我使用 conda 重现了您的问题。 conda 似乎将 ~/.bash_profile 配置为与 PYTHONPATH 混为一谈。您可以尝试在 Python 解释器中通过以下代码检查 PYTHONPATH。

>>> import sys
>>> sys.path

默认 Python 包由 OS 安装在路径 /usr/local/lib/python2.7/site-packages & /Library/Python/2.7/site-packages，但 conda 安装 python 包在路径 ~/anaconda/lib/python2.7/site-package 并配置 ~/.bash_profile 以设置本地 PYTHONPATH（不是全局，不需要 sudo）。

要解决此问题，请尝试使用命令 virtual env --no-setuptools --no-pip --no-wheel。
