Python 2.7 PIP install to use Artifactory as proxy

Question

I have configured Jfrog Artifactory as remote repo for PIP module. When I install the pexcept module on Centos 7 OS, its downloading using the Artifactory proxy, but its giving below error message. Also it trying to connect https://pypi.python.org/pypi/pip/json website.

Any tips to fix below error? Also How can I force pip command to use always internal Artifacotry proxy not to connect any external repo directly.

Answer 1

I am presently using artifactory for just this purpose. I did find that some packages did not resolve well. After changing to https://files.pythonhosted.org as the registry URL everything just fell into place.

my other settings are

• Repository URL: https://files.pythonhosted.org
• Registry Layout simple-layout
• Pypi settings
  • Registry URL: https://pypi.org
  • Registry Suffix: simple
