Pipenv: ERROR: Could not find a version that matches requests

Created on 21 Feb 2019 · 16Comments · Source: pypa/pipenv

I ran:

$ mkdir test
$ cd test
$ pipenv install requests

but this caused the following error:

ERROR: ERROR: Could not find a version that matches requests
No versions found
Was https://pypi.org/simple reachable?

I thought this problem is due to proxy, but the following successfully run.

$ pip install requests

Please help me...

These steps solved similar issue I had recently:

Delete the virtual environment and pipfile(s)

$ pipenv --rm 
$ rm Pipfile
$ rm Pipfile.lock

then reinstall project dependencies
$ pipenv install package1 package2 package3

Yeah pipenv doens't read the proxy settings set somewhere in pip.conf.

Please use HTTP_PROXY/HTTPS_PROXY env vars instead

frostming on 21 Feb 2019

Thanks for reply!
However, I cannot resolve this issue.
I ran:

$ export HTTP_PROXY=http://my-proxy-server:port
$ export HTTPS_PROXY=http://my-proxy-server:port
$ pipenv install requests

What should I do?

tamuhey on 21 Feb 2019

@tamuhey What step are you stuck in? Installation or locking? Was virtualenv created successfully?

frostming on 21 Feb 2019

@frostming Virtual env seems to be created successfully:

$ pipenv --where
$HOME/test

I think installation succeeded, but locking failed:

$ pipenv install requests

I had a similar issue when I tried to create a new project. The workaround I found was to write the Pipfile myself:

[[source]]
url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"

[packages]
requests = "*"

any progress on this issue? this is a pip connectivity issue it seems like

if you can't make further progress please provide the output of pipenv install --verbose

I think this problem is due to proxy, because the following command successes

I'm facing a similar issue but haven't seen any resolution on this. I even removed verify_ssl=True from the pipfile but not success.

This is a problem with the proxy or firewall. Just try and add the HTTP_PROXY to you ~/.profile and see if it works.

ghost on 9 Apr 2019

@tamuhey From your last comment, it seems to due to a broken installation of Python.

You need to reinstall Python with SSL module enabled.

Not active for a long time, close it now.

I had installed Python 3.7.4 using pyenv and I don't fully understand the reason but my Pipfile had this line in package list

[packages]
3-7-4 = "*"

Removing the 3-7-4 line fixed the issue for me.

This issue occured for me when I installed a brew package that installed a new version of python on my machine (3.8 vs 3.7.x which I was using)

When it did this it broke the OpenSSL installation that pip was using. This was the reason that it could not find any versions on pip.

I ended up having to reinstall python with:

brew reinstall python

Anybody having problems with locking pipenv but it worked the first time around creating a virtualenv: copy the Pipfile in your new directory then try locking it again using pipenv lock

Locking [dev-packages] dependencies…
Locking [packages] dependencies…
Success!
Updated Pipfile.lock (30ae14)!
