问题
Im attempting to install pip with python 2.6 on my dev machine to try to match a deployment environment that also uses python 2.6.
Python 2.6 is installed OK. I've tried installing pip using get-pip.py as outlined here https://pip.pypa.io/en/stable/installing/ with the version of the get-pip.py script from https://bootstrap.pypa.io/2.6/get-pip.py
However it fails with the following:
C:\users\me> python get-pip.py
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6

Could not fetch URL https://pypi.python.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.python.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError(SSLError(1, '_ssl.c:490: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version'),)) - skipping
Could not find a version that satisfies the requirement pip<10 (from versions: )
No matching distribution found for pip<10
Obviously, upgrading to newer python defeats my purpose.
The information at the URL recommended for the warning InsecurePlatformWarning suggests that I install more things using pip... >.<
PS I've tried using easy-install from setuptools-40.0.0 as well, but I could not get this to work. I'm not sure if I'm using it correctly as the setuptools installation documentation has circular links (from the documentation to Pypi, back to the documentation)
回答1:
For Python 2.6 you need older setuptools. The last setuptools version that works with Python 2.6 is 36.8.
Download setuptools-36.8.0.zip, unpack and run python2.6 setup.py install.
After that get-pip.py should install pip for you.
The last version of pip supporting Python 2.6 is 9.0.3: https://pypi.org/project/pip/9.0.3/#files
