➜  ~ sudo pip install pandas

Collecting pandas

  Could not find a version that satisfies the requirement pandas (from versions: )

What am I doing wrong?

Answer 1

This is due to the recent TLS deprecation for Python.org sites.

This answer has the details.

To summarize, upgrade pip as follows:

curl https://bootstrap.pypa.io/get-pip.py | python

and then run:

pip install pandas

Answer 2

I would try sudo chown -R your_user_name /Users/bdisha/Library/Caches/pip/http and chown -R your_user_name /Users/bdisha/Library/Caches/pip

搜寻了很长一段时间后，我尝试了这个 。
