No module named sh

Question

I installed sh for native python, and I started using commands to install:

$ 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

When the above fails, I download sh-1.12.14-py2.py3-none-any.whl to install locally:

$ 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'

This path is right. It does exist:

$ cd /Users/zhangkuixun/Downloads/
$ ls
...
sh-1.12.14-py2.py3-none-any.whl

How can I install SH and reference it? Now the reference fails:

Is `pypi.python.org` *really* using TLSV1? I almost wonder if you're subject to a man-in-the-middle attack... — Charles Duffy, Dec 19 '18 at 02:18
...indeed, when I look at it myself (`openssl s_client -connect pypi.python.org:443`), they're using TLSv1.2. Could you provide the fingerprint of the SSL certificate you get for that site here, so we can check whether it matches what the real/public server is using? See [Get certificate fingerprint of SSL server from command line](https://stackoverflow.com/questions/5164804/get-certificate-fingerprint-of-https-server-from-command-line) — Charles Duffy, Dec 19 '18 at 02:19
The error is quite simple: `No such file or directory: '/Users/zhangkuixun/Downloads/sh-1.12.14-py2.py3-none-any.whl'` Do you have the file in that location? — Lie Ryan, Dec 19 '18 at 02:25
@LieRyan, ...yes, the *second* error is simple (downloaded filename just not passed to `pip` correctly), but the *first* error is extremely worrisome. If the OP did the download with a tool that isn't checking SSL certificate types, and their system is configured to accept a CA cert owned by whomever's MITM'ing them, then what they're trying to install via the second set of instructions could well be trojaned. — Charles Duffy, Dec 19 '18 at 02:26
...granted, if that's a security service or otherwise an "authorized" attacker, it may be less of something one can do anything about. — Charles Duffy, Dec 19 '18 at 02:28
BTW, it's better practice to edit [an unanswered question](https://stackoverflow.com/questions/53774801/download-error-on-https-pypi-python-org-simple-sh-ssl-tlsv1-alert-protocol) than to ask it over again. — Charles Duffy, Dec 19 '18 at 02:32
@Lie Ryan @Charles Duffy Yes, I have this file. I download `sh-1.12.14-py2.py3-none-any.whl` to `/Users/zhangkuixun/Downloads/sh-1.12.14-py2.py3-none-any.whl`. I can execute `open /Users/zhangkuixun/Downloads/sh-1.12.14-py2.py3-none-any.whl`,Just no app can open it. — Kuixun Zhang, Dec 19 '18 at 02:57
