Compatibility with yarn 2 (or yarn 1 PnP mode)

See original GitHub issue

Current Behavior

Yarn v2 got a stable release today, and it uses PnP (instead of node_modules) exclusively Right now tsdx test, tsdx build (and maybe others) have some issues with it (specially with finding the typescript package if it is not globally installed, which would be my case).

Desired Behavior

TSDX should work out of the box with yarn v2 / yarn v1 PnP mode

Who does this impact? Who is this for?

People who use yarn v1 PNP mode and/or yarn v2.

Gonna press pause until this is sorted out: https://github.com/yarnpkg/berry/issues/766#issue-555117544

I’ll mark this as PR welcome. node_modules is referenced in a few places and I know some of our dependencies rely on it too, so I don’t think the amount of work for this is trivial. We’d also have to support both versions too, not just Berry. And probably run tests against both versions in CI too.

Not really a high priority given amount of work, other priorities, and that the community hasn’t really moved on to Berry as a whole (including little interest in this issue and the fact that it’s not the default version).
