无法在公司防火墙后安装PIP

Question

I am trying to install PIP using python get-pip.py and since I am behind a corporate firewall, the installation keeps failing.

 $ python get-pip.py
Collecting pip

Is there a workaround for this? Is there a way I can turn off the verification?

I have also tried curl -o get-pip.py https://bootstrap.pypa.io/get-pip.py

 $ curl -o get-pip.py https://bootstrap.pypa.io/get-pip.py

curl: (60) SSL certificate problem: self signed certificate in certificate chain
More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

Can I download the certificate for verification/turn verification off? Really stuck with this!
