Poetry fails with KeyError if the PATH environment variable is not present

• 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: Ubuntu 18.04

• Poetry version: 1.0.10

Issue

When running in CI using a docker container the PATH environment variable is not set and causes an issue with poetry. Unfortunately I don’t see any traceback. Here’s a snipped showing the issue:

root@5d1e49d5433c:~/src# unset PATH
root@5d1e49d5433c:~/src# /usr/local/bin/poetry run -vvv pip install pip

[KeyError]
'PATH'

@abn Fair point. Here is the issue: #3199 Hope that would help someone reproduce it.

@pepastach I am not sure you have provided any actionable information there. Perhaps details on how we can reproduce concern you have raised would be a start, -vvv logs would also go a long way to help. Since this issue is already closed, I would recommend creating a new issue if an open one for the errors you are facing does not already exist.

@Jihadik @pepastach if you are encountering issues with the new installer, you can refer here on how it can be disabled until it stablises.

@Jihadik Regarding the Connection pool is full, discarding connection: pypi.org, that is the requests library recreating connections to pypi.org, it is a graceful recovery and should not impact functionality under normal circumstances. Regarding the errors, as I mentioned above, more details will be appreciated.
