Python PIP安装问题

安装以下部件有很大困难： argparse==1.2.1，beautifulsoup4==4.3.2&wsgiref==0.1.2。每次尝试安装其中任何一个时，我都会收到相同的错误：

C:\>pip install -r requirements.txt

要安装这些东西或清除缓存，我可以做些什么？我可以很好地安装其他软件包。

您是否已将pip和安装工具升级到最新版本？@hexerei software pip install-upgrade pip？它说它已经是最新的了。编辑：忘了提到setuptools也是最新的。我能告诉你的是，当他试图从windows注册表获取系统mime类型时，他得到了一个空字符串。。。也许是权利问题？以管理员身份运行？您的注册表中没有注册表项？在那里的某个地方，坏事情正在发生：除非进行擦除，否则如何解决这个问题？我很乐意提供帮助，但我只在vm中使用windows，而且很少使用。自古以来，在Mac和Unix世界中都很快乐：
