Poetry doesn't resolve on MacOs Mojave

[wilfredinni]

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: MacOs Mojave

• Poetry version: 0.12.12

Issue

poetry update command doesn't work on my Mac. Just stay in resolving dependencies. My machine with Manjaro Linux, a 7 years old laptop, resolves in 8 seconds the same pyproject.tom.

Tried this out because I'm also running Mojave on my Mac, but I wasn't able to repro. I got the following output:

I am on Poetry 0.12.11, though; what happens if you downgrade? Perhaps a bug was introduced in the newest release.

@tuchandra the first time I install the dependencies I have no problems either. Can you try to use poetry update and see what happens now? Thank you.

Running it again works fine:

Updating dependencies
Resolving dependencies... (0.3s)

Nothing to install or update

:/

[wilfredinni]

Removed Poetry, all the virtualenvs and cleaned the cache folder, then reinstalled it. All is good now.

@wilfredinni sounds about right

Here is a related issue, which may offer a bit of explanation (TLDR has to do with cachecontrol/filelock libs)

@wilfredinni Since this seemingly is not about OS, and since there are known resolutions, could you edit the ticket title and/or close the ticket?
