Couldn't install pylint in Python2.7 and get not matched errors even install with the local setup.py

Question

For the developing environment constrained I have to use Python2.7 in the Windows10.
So I choose to install pylint as the linter I use in the Administrator Mode.

pip install "pylint<2.0.0"

But it only outputs as follows:

WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(, 'Connection to pypi.org timed out. (connect timeout=15)')': /simple/pylint/

And this message repeat many times then give such output:

ERROR: Could not find a version that satisfies the requirement pylint<2.0.0 (from versions: none) ERROR: No matching distribution found for pylint<2.0.0

So I download a 1.9.3 version in the PyPI.
And tried to install it with setup.py in the Administrator Mode as follows:

python setup.py install

BUT also get the same problems as before:

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(, 'Connection to pypi.org timed out. (connect timeout=15)')': /simple/pylint/

ERROR: Could not find a version that satisfies the requirement pylint==1.9.3 (from versions: none)

ERROR: No matching distribution found for pylint==1.9.3

And I also tried the older version like 1.8.4, 1.7.4 and so on.

BUT it still got other problems here, which is messed with me all day.

So could anyone help me or give some hints?
Thanks in advances.

Answer 1

First of all, you should avoid Python2.7 if possible, since it is no longer supported.

You might be behind a firewall that blocks these connections. If that's your problem, try this.
