PyPlot build error on MacOS

[stumarcus314]

I am trying to add the PyPlot package to julia version 0.6.2 on MacOS version 10.12.6, but get the following build error:

julia> Pkg.add("PyPlot") WARNING: julia is fixed at 0.6.2 conflicting with requirement for POD: [0.5.0,0.6.1-) INFO: Installing Conda v0.7.1 INFO: Installing LaTeXStrings v0.3.0 INFO: Installing MacroTools v0.4.0 INFO: Installing PyCall v1.15.0 INFO: Installing PyPlot v2.5.0 INFO: Building Conda INFO: Building PyCall INFO: Using the Python distribution in the Conda package by default.

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. HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure. ================================[ ERROR: PyCall ]================================

Seems like a network problem. Are you behind some kind of corporate firewall?

I was behind a corporate firewall. I switched over to the guest wi-fi, which is not behind a firewall, and the installation of the PyPlot package worked. Thanks.
