Issue description

When the environment variable PIPENV_SITE_PACKAGES is set, pipenv always recreate new virtualenv on each invoke of pipenv even if it is not a pipenv install command.

Expected result

• pipenv run or pipenv shell should use existing virtualenv instead of creating a new one.
• PIPENV_SITE_PACKAGES should only affect pipenv install command.

Actual

We're doing a bunch of code quality cleanup, and as part of that effort I'd like to implement some additional lints/coding conventions. There will be a lot of manual changes here, so I think these will be some items to have multiple people tackle.

In no particular order:

• Add ban-relative-imports = true to .flake8 and remove relative imports from the repo.
• ~Add `flake8-type-checki

Current Behavior

UMD build doesn't support code-splitting and dynamic imports (rollup/rollup#3490, rollup/rollup#3491) due to Rollup current limitations, and tsdx cli don't accept the format option amd when creating build config

Suggested Solution

Consider support AMD module format, o

What's the problem this feature will solve?

Since pip freeze generates constraints in the form of " @ " and pip subsequently understands that format, it seems to me that the documentation at https://pip.pypa.io/en/stable/topics/vcs-support/ should describe that format in addition to the "#egg=" format.

Since the "…@…" format is what pip gener

Github introduced a nice UI for syncing your fork with upstream.

We could use something like that for package links. osc has the setlinkrev command for this.
