Issue

with Poetry 1.6.1, poetry install command fails with exit code != 0:

❯ poetry161 install
Installing dependencies from lock file

[Errno 2] No such file or directory: '/home/jovyan/repo/sarasvati/temp/README_does_not_exist'

but Poetry 1.7.0 do not fail:

❯ poetry install   
Installing dependencies from lock file

Installing the current project: test (1.0.0)
The current project could not be installed: [Errno 2] No such file or directory: '/home/jovyan/repo/sarasvati/temp/README_does_not_exist'
If you do not want to install the current project use --no-root

I guess this behavior was introduced by #8369 .

In daily development, it's ok, one can see the warning messages.

But in my usecase, poetry install in Dockerfile,
docker build doesn't fail if i forget to copy README like COPY README.md.

This result is very confusing, and I expect to return failure exit code if attempting to install package was failed.

Thanks! :)
