没有名为 sh 的模块

Question

我安装了sh原生Python，并开始使用命令来安装：

$ 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

当上述失败时，我下载sh-1.12.14-py2.py3-none-any.whl安装到本地：

$ 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:
'/Users/zhangkuixun/Downloads/sh-1.12.14-py2.py3-none-any.whl'

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：

$ python
Python 2.7.10 (default, Feb  7 2017, 00:08:15) 
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sh
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named sh
>>> 

Answer 1

解决了：

1.到这里https://pypi.org/project/sh/#files下载sh-1...14.tar.gz

2.执行命令：sudo easy_install /YourPath/sh-1.12.14.tar.gz
