无法在虚拟env中执行pip

Question

我试图在虚拟env中安装django-rq，但遇到了以下错误：

pip安装django-rq

Collecting rq>=0.3.4 (from django-rq)
  Using cached rq-0.5.1-py2.py3-none-any.whl
  Hash of the package https://pypi.python.org/packages/py2.py3/r/rq/rq-0.5.1- py2.py3-none-any.whl#md5=45418bdc995c394b4293180a4c29cb88 (from 
https://pypi.python.org/simple/rq/) (e9d365b19b099235441599de78b25042)   doesn't match the expected hash 45418bdc995c394b4293180a4c29cb88!
  Bad md5 hash for package https://pypi.python.org/packages/py2.py3/r/rq/rq-0.5.1-py2.py3-none-any.whl#md5=45418bdc995c394b4293180a4c29cb88 (from https://pypi.python.org/simple/rq/)

我试着在虚拟环境之外安装它，它运行得非常好。但我不知道为什么它没有安装在虚拟环境中。

似乎pip正在尝试安装模块形式的本地缓存，请参阅这里的更多细节：How do I install from a local cache with pip?

试着使用这样的方法：

pip install --no-cache-dir django-rq
