sorry for the basic question. I am very confused as to why my pip is not working on a remote unix machine. I have installed Python 3.5 in my home directory. In my PATH I have added 

~/lib/python3.5

I also added to .bashrc

$ alias python=~/bin/python3.5

so when I type $ python in the command line, I get python 3.5. I can import pip from inside python (import pip) no problems. However using

$ pip install cython

I get: '-bash: pip: command not found' And if I try:

$ python -m pip install cython

I get:

'Collecting cython

Could not find a version that satisfies the requirement cython (from versions: ) No matching distribution found for cython'

Pip does not seem to be installed properly. Do I need to add anything to .bashrc?

  • From the [python website](https://www.python.org/downloads/), the latest stable version is version 3.4.3. Did you look on the issues of the pre-release of python? – llrs Jun 02 '15 at 10:49
  • No, but I tried this with 3.4 and also got the same message – kezzos Jun 02 '15 at 10:51

    Try to find the actual `pip` executable in your local install. It seems not to be in *~/lib/python3.5*, directly. Also, try with `pip -v -v -v install cython` to get more information on why the search fails. – dhke Jun 02 '15 at 10:54
  • Nice. I can see a connection gets established but the SSL certificate fails: Could not fetch URL https://pypi.python.org/simple/cython/: connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:646) - skipping – kezzos Jun 02 '15 at 10:59
  • I just found this: http://stackoverflow.com/questions/25981703/pip-install-fails-with-connection-error-ssl-certificate-verify-failed-certi which may be the same problem – kezzos Jun 02 '15 at 11:03
  • Make sure your clock is set correctly. – rmalouf May 30 '16 at 21:00
