After all official installment, error happened:
Could not fetch URL https://pypi.python.org/simple/ssl/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777) - skipping
Could not find a version that satisfies the requirement ssl (from versions: )
No matching distribution found for ssl
I address this problem by adding path to environment 😥
Not only: anaconda & anaconda\Scripts
But also need anaconda\Library\bin
Oh my god！
