I got the solution ,Try with --allow-unverified

我得到了解决方案，尝试使用--allow-unverified

syntax: pip install packagename=version --allow-unverified packagename

语法：pip install packagename=version --allow-unverified packagename

Some package condains insecure and unverifiable files. it will not download to the system . and it can be solved by using this method --allow-unverified. it will allow the installation.

一些包包含不安全和无法验证的文件。它不会下载到系统。并且可以通过使用此方法--allow-unverified来解决。它将允许安装。

Eg:pip install django-ajax-filtered-fields==0.5 --allow-unverified django-ajax-filtered-fields

例如：pip install django-ajax-filtered-fields==0.5 --allow-unverified django-ajax-filtered-fields

Inspecting the logs reveals the following line:

检查日志显示以下行：

less .pip/pip.log

Could not fetch URL https://pypi.python.org/simple/WSGIUtils/: connection error: [Errno1] _ssl.c:493: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

In an earlier version of the comment I attributed this behaviour to https://pypi.python.org, but this is not the issue, since I can contact this site (from another computer!) with firefox and all certificates are OK. So this is probably a problem of some installations of pip---I encounter it unter SLES 11 which has (among other things) the "oldstable" openssl-0.9.8.

在较早版本的评论中，我将此行为归因于https://pypi.python.org，但这不是问题，因为我可以使用 firefox 联系该站点（从另一台计算机！），并且所有证书都可以。所以这可能是某些 pip 安装的问题——我在 SLES 11 下遇到了它，它具有（除其他外）“oldstable”openssl-0.9.8。

Still unsure if myissue has the same cause as with the OP, but one error message was the same:

仍然不确定我的问题是否与 OP 的原因相同，但一条错误消息是相同的：

  Cannot fetch index base URL https://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement Django
No distributions at all found for Django

Talking to a colleague exposed it was a site-security-based issue. The following commands were required:

与同事交谈后发现这是一个基于站点安全的问题。需要以下命令：

set https_proxy=*https proxy*
set http_proxy=*http proxy*
pip install Django

where *https proxy*and *http proxy*are appropriate URLs-with-ports for our site.

在哪里*https proxy*和*http proxy*是我们网站的合适的带有端口的 URL。

The only solution worked for me:

唯一的解决方案对我有用：

1. uninstall pip (pip uninstall pip)
2. download pip package from pypi (https://pypi.org/project/pip/)
3. execute python setup.py install (not using easy_install)
4. then you can install any package you want.

1. 卸载点子（点子卸载点子）

Lots of solutions to this, most effectively coming down to update PIP. On MacOS (Sierra), This was my solution:

对此有很多解决方案，最有效的是更新 PIP。在 MacOS (Sierra) 上，这是我的解决方案：

• Download python3 installer of choice
• Install Package (this includes a newer version of pip)
• Remove old version of python from $PATHin ~/.bash_login(new one added by installer)
• pip3 install packagename(no sudo)

• 下载选择的python3安装程序
• 安装包（这包括较新版本的 pip）
• 从$PATHin 中删除旧版本的python ~/.bash_login（安装程序添加的新版本）
• pip3 install packagename（没有须藤）

After that I was still prompted to update pip and did so: pip3 install --upgrade pip

在那之后，我仍然被提示更新 pip 并这样做了： pip3 install --upgrade pip
