Pipenv Locking failed

Question

Pipenv is failing to lock the Pipfile, either when installing modules or with pipenv lock

I am trying to set up pipenv to use in my projects at work. I use a corporate proxy and have a pip.ini config file set up, this has worked with pip for installs and virtualenv.

Not sure if this is an issue with the proxy, which works for pip installs. I've also read that there may be an environment variable I need to change.

I tried installing requests, and pipenv is able to create the environment and install the dependencies, but is not able to lock the Pipfile. It is able to install if I use --skip-lock. But if I go to install/update anything, or lock the file with pipenv lock (including --clear), it fails. Traceback is below, am I reading it right that its starting with an SSL issue?

Answer 1

Try clearing the cache for your package manager by running the following command:

pipenv --clear

If the above steps doesn't resolve the issue, the problem may be specific to pipenv so use a different package manager like 'pip".

I think either of the one will resolve the issue.

Answer 2

The comment regarding setting the proxy value worked. I hadn't been using 'http://' in front in my config file. This however created a different issue with the SSL request. I was getting an error that said my request was attempting to use https instead of http. Someone recommended I set the environment variables HTTP_PROXY and HTTPS_PROXY in my terminal. This initially didn't solve the issue, until I read the wording of the error. Turns out I had to set both the above variables to the same value.

$ENV:HTTP_PROXY='http://proxy:port"
$ENV:HTTPS_PROXY='http://proxy:port"  <-- **not 'https://'**

The requests are now properly going through the proxy and completing, and then locking the file. Thanks all!
