Question

尝试使用pip安装应用程序时出现以下错误。

    Collecting django

    File "C:\Python34\lib\site-packages\pip\_vendor\requests\packages\urllib3\poolmanager.py", line 216, in __init__
      'Not supported proxy scheme %s' % proxy.scheme
  AssertionError: Not supported proxy scheme abden003

我试过运行以下命令，但在两种情况下都得到了相同的错误（我尝试过使用python和python3）：

pip install django

pip install django --proxy http://abden003:password@proxy.server.addr:port

pip3 install django

pip3 install django --proxy http://abden003:password@proxy.server.addr:port

问题不在于我的代理服务器，因为我在Linux vm中尝试过它并且工作正常。它似乎是pip的Windows版本的一个问题。

我尝试过以下操作，但它没有解决问题：

pip, proxy authentication and "Not supported proxy scheme"

我已经找到了解决问题的方法，它涉及删除一行代码。如果您查看最后一个错误，则说明以下内容：

    File "C:\Python34\lib\site-packages\pip\_vendor\requests\packages\urllib3\poolmanager.py", line 216, in __init__
      'Not supported proxy scheme %s' % proxy.scheme
  AssertionError: Not supported proxy scheme abden003

转到：

 C:\Python34\lib\sitepackages\pip\_vendor\requests\packages\urllib3\poolmanager.py

在我的情况下，我去了C：\ Python34 \ Lib ..而不是C：\ Python34 \ lib

打开poolmanager.py文件，并删除第215行，其中包含以下内容：

    #  assert proxy.scheme in ("http", "https"), \
    #    'Not supported proxy scheme %s' % proxy.scheme

我不知道这条线是否被意外遗留，但是删除修复了问题，我可以通过pip安装包

你应该在命令提示符而不是python shell中运行pip install django。

无法通过pip在Windows上安装应用程序
