It's because PyPI has disabled non HTTPS access to APIs

https://mail.python.org/pipermail/distutils-sig/2017-October/031712.html

as workaround you can use

$ pip install xxxx -i https://pypi.python.org/simple/

Unfortunately none of the previous answers work for me.

IMHO it was very stupid pip / distutils chose to break packages on http repos.

I think a better choice would have been:

pip/distutils use https by default
in case of error, like 403, pip has to suggest you "the package repo is on http, do you want to download it?"

Still in 2020 many Python 2 packages are on http repos; with their decision, the installation of these packages is broken.

The working solution for me is a very simple patch of one python core modules:

--- /usr/local/lib/python2.7/urllib2.py.original
+++ /usr/local/lib/python2.7/urllib2.py
@@ -427,6 +427,9 @@
             req = meth(req)

         response = self._open(req, data)
+        if protocol == "http" and response.code == 403 :
+            if isinstance(fullurl, basestring) and fullurl.startswith("http://pypi.python.org/packages/source/d/distribute/") :
+                return    self.open(fullurl.replace("http://", "https://"), data = data, timeout = timeout)

         # post-process response
         meth_name = protocol+"_response"

Working: if the failed url is on http, retry on https.

I know it is a little ugly, but it is very clear and also you can revert to the original module in a snap (make a copy of /usr/local/lib/python2.7/urllib2.py before to apply this patch).
