Using --target with --editable results in "internal" error

It seems like --target is not supported when using --editable at the same time. It would be nice to have it working. Meanwhile there should be some better diagnostic as

I’d add that this is an issue for Google Appengine developers who need to install their dependencies in a directory in the app root but also need to deploy an editable dependency in a local checkout as part of a QA process. As it sits, the editable would need to be manually symlinked which is cumbersome.

I just experienced the same issue. As suggested by @jezdez you can work around this by doing the following (without using --editable that is):

git+ssh://[e-mail]/some-user/some-repo.git#egg=Foo
