PIP connection Error : SSL CERTIFICATE VERIFY FAILED

The most common issue in installing python package in a company's network is failure of verification of SSL Certificate. Sometimes company blocks some websites in their network so employees can't access these websites. Whenever they try to visit these websites, it shows "Access Denied because of company's policy". It causes connection error in reaching main python website.

Error looks like this :

Could not fetch URL https://pypi.python.org/: connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:598)

Solution :

Run the following command. Make sure to specify package name in <package_name>
pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org <package_name> -vvv
Suppose you want to install pandas package, you should submit the following line of command
pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org pandas -vvv
