OpenSSL: installed by Homebrew
The Answer http://stackoverflow.com/questions/24675167/ca-certificates-mac-os-x
The Problem
$ pip install tox
Collecting tox
Could not fetch URL https://pypi.python.org/simple/tox/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645) - skipping
Could not find a version that satisfies the requirement tox (from versions: )
No matching distribution found for tox
SSL errors caused and can not continue installing … :cry:
The Solution
Open Keychain Access and select all certs in system root and export them.
Save exported pem into /usr/local/etc/openssl/certs. (← check brew info openssl)
Then run rehash command.
$ /usr/local/opt/openssl/bin/c_rehash
$ pip install tox
Requirement already satisfied: tox in /usr/local/lib/python2.7/site-packages
