I suggest GitLab CE uses the alternate syntax for SSH clone URLs, using a slash instead of a colon in between the host & path URL parts: ``` <protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>[#<commit-ish> | #semver:<semver>] prefer the slash here ^ ``` **Why?** Because of [this npm bug](https://github.com/npm/npm/issues/17621) between npm -v 5.1 and up to at least 5.6 (roughly node -v 8-10), semver ranges don't work if the URL uses the colon, but does work with slashes. [I've also suggested](https://github.com/npm/npm/issues/17621#issuecomment-386549609) updating the [examples in the official npm docs](https://docs.npmjs.com/files/package.json#git-urls-as-dependencies) and created a [stackoverflow question](https://stackoverflow.com/questions/50160639/git-ssh-url-with-semver-range-as-npm-dependency) to help people avoid this bug. **Examples** These URLs work: ``` # with slash between host & path git+ssh://git@gitlab.example.com/path/repo.git git+ssh://git@gitlab.example.com/path/repo.git#branch_1_2 git+ssh://git@gitlab.example.com/path/repo.git#1.2.3 git+ssh://git@gitlab.example.com/path/repo.git#semver:^1.2.3 git+ssh://git@gitlab.example.com/path/repo.git#semver:~1.2.3 # with colon between host & path git+ssh://git@gitlab.example.com:path/repo.git git+ssh://git@gitlab.example.com:path/repo.git#branch_1_2 git+ssh://git@gitlab.example.com:path/repo.git#1.2.3 ``` but this doesn't work ([depending on the npm version](https://github.com/npm/npm/issues/17621#issuecomment-323000627)): ``` # with colon between host & path git+ssh://git@gitlab.example.com:path/repo.git#semver:^1.2.3 git+ssh://git@gitlab.example.com:path/repo.git#semver:~1.2.3 ```
