这个问题在这里已有答案：
我为本机python安装了sh，我开始使用命令安装：
$ pip install sh
Collecting sh
Could not fetch URL https://pypi.python.org/simple/sh/: There was a problem confirming the ssl
certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping
Could not find a version that satisfies the requirement sh (from versions: )
No matching distribution found for sh
当上述操作失败时，我下载sh-1.12.14-py2.py3-none-any.whl进行本地安装：
$ pip install
/Users/zhangkuixun/Downloads/sh-1.12.14-py2.py3-none-any.whl
Requirement
'/Users/zhangkuixun/Downloads/sh-1.12.14-py2.py3-none-any.whl' looks
like a filename, but the file does not exist
Processing ./Downloads/sh-1.12.14-py2.py3-none-any.whl
Exception:

IOError: [Errno 2] No such file or directory:

这条路是对的。它确实存在：
$ cd /Users/zhangkuixun/Downloads/
$ ls
...
sh-1.12.14-py2.py3-none-any.whl
如何安装SH并引用它？现在引用失败了：

解决了：
1.到这里https://pypi.org/project/sh/#files下载sh-1...14.tar.gz
2.executive命令：sudo easy_install /YourPath/sh-1.12.14.tar.gz
