urllib2.HTTPError：HTTP 错误 403：需要 SSL，即使升级了 pip 并使用了 --index 选项

Question

我已经读过Cannot install distribution: pypi.python.org Rejecting http和Getting error 403 whileInstalling package with pip但解决方法不起作用

在尝试做的同时

pip install --upgrade pyls --index-url=https://pypi.python.org/simple我有 ：

Collecting pyls
  Using cached pyls-0.1.3.zip
    Complete output from command python setup.py egg_info:

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-hdpX4y/pyls/

我的python版本是2.7，我的pip版本是

pip 9.0.2 from /usr/local/lib/python2.7/dist-packages (python 2.7)

重现：

旋转此 docker 实例https://hub.docker.com/r/allansimon/allan-docker-dev-python并在其中启动命令（使用 user vagrant）

我尝试过它对我有用：

pip install --upgrade pyls -i https://pypi.python.org/simple
