无论我尝试安装哪个软件包，都会出现此错误：

error: invalid command 'egg_info'

----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1 in c:\users\zorpix\appdata\local\temp\pip-build-Zorpix\virtualenv
Storing complete log in C:\Users\Zorpix\pip\pip.log

我看到了这个问题，但答案对我不起作用。我可以安装分发程序包，到目前为止，它是我唯一可以安装的程序包，但是它不能解决问题，因为在我尝试安装另一个程序包时，egg_info错误立即返回。我对此感到非常沮丧，因为我在任何地方都找不到任何帮助。我之前也已经安装了django和pip以及所有内容，但是我不得不重新安装所有内容，现在它不起作用了。任何帮助将不胜感激。

这是它说存储的日志：
