Problem installing package in an isolated environment #87

Closed nadavaviv closed 4 years ago

nadavaviv commented 4 years ago

I'm trying to install a package in an AWS instance which is not accessible to the pypi.org. I had to upload it to a private repository using s3pypi. (With all dependencies of course)

when trying to install said package, this is the stack trace I get:

Traceback (most recent call last):
  File "/opt/conda/lib/python3.7/site-packages/pip/_internal/cli/base_command.py", line 188, in main
    status = self.run(options, args)

    resolver.resolve(requirement_set)

    raise BackendUnavailable
pip._vendor.pep517.wrappers.BackendUnavailable

Is there maybe a way to work around this? Thanks

Hi! Thanks for filing this but this isn't the right place for this issue.

I think that python-list or python-tutor mailing lists, #python on Freenode (IRC) or StackOverflow would be better channels to get support for the issue you're facing.
