I cannot install plotly

When I try to install plotly with pip in a Mac with python 2.7, i get the following message:

Collecting plotly
Could not fetch URL https://pypi.python.org/simple/plotly/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:661) - skipping
Could not find a version that satisfies the requirement plotly (from versions: )
No matching distribution found for plotly

Are you using Anaconda by any chance? If so, have you tried installing using Conda?

Hi @RBarneto,

I’m not very familiar with pip’s internals, but it sounds like you may be running into this issue: https://github.com/pypa/pip/issues/5226.

If so, sounds like you need to get pip updated to at least 9.0.3

So I would suggest using that issue thread as a starting point for diagnosing the issue.

Hope that helps get you pointed in the right direction.


No, I don’t.
