if i use pymongo instead of pyautogui, it will not throw error follow above procedue.

Fixed in 1.1.0b2. Requires regeneration of lock file. Note that new lock file is not compatible with older versions of poetry.

[danihodovic]

While 1.1.0b2 fixes this issue, it breaks git installs. @abn do you have a recommendation for people that are facing both issues?

[abn]

@danihodovic what is the breakage?

[danihodovic]

1.1.0b2 fails to install git packages. Versions before 1.1.0b2 cause the recursionerror. I've resorted to downgrading to 1.10 and re-installing all dependencies

[abn]

@danihodovic sorry to be obtuse, but I tried using master and the issue does not seem to exist. Would you be able to provide a quick example? I might be missing something.

#2817?

[danihodovic]

I didn't update poetry-core to master. I didn't even know that package existed. I will try it out. Thanks
