• 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 20.04
• Poetry version: 1.2.0
• Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/amcinnes/8c61ad88b37a7740dd93efa976f85ed7

Issue

To reproduce the issue:

docker run --rm -it ubuntu:20.04@sha256:af5efa9c28de78b754777af9b4d850112cad01899a5d37d2617bb94dc63a49aa
apt-get update && apt-get -y install python3-pip
python3 -m pip install poetry==1.2.0
poetry config virtualenvs.create false
poetry init -n
poetry add awscli
aws --version

Expected behaviour (seen with poetry 1.1.14): the aws command runs successfully.

# aws --version
aws-cli/1.25.70 Python/3.8.10 Linux/5.19.7-arch1-1 botocore/1.27.69

Observed behaviour (with poetry 1.2.0): the aws command fails.

# aws --version
Traceback (most recent call last):
  File "/usr/bin/aws", line 19, in <module>
    import awscli.clidriver
ModuleNotFoundError: No module named 'awscli'

This seems to be because with poetry 1.2.0, awscli has been installed into /usr/lib/python3.8/site-packages/awscli which is not in the Python path.
