Unable to install packages with pip install ( behind corporate proxy)

Question

Unable to install python packages by "pip install pandas".

I am behid corporate proxy. Environment variable for HTTP_PROXY & HTTPS_PROXY is also set but still unable to install packages

pip config edit gives following log

proxy = https://192.168.0.1:8080 timeout = 60

Also tried ( as suggested by Say. W )

pip -v --log /tmp/pip.log --trusted-host pypi.python.org --trusted-host pypi.org --trusted-host files.pythonhosted.org install pandas

but still same error

Please help to suggest how to resolve this issue?

Thanks, Gaurav
