[Bug] yarn add fails by specifying the remote URL

[flymans]

• I'd be willing to implement a fix

Describe the bug

After calling yarn add <git remote url> error is thrown: Invalid descriptor.
For example:

yarn add https://github.com/fancyapps/fancybox
Internal Error: Invalid descriptor (https://github.com/fancyapps/fancybox)
    at Object.parseDescriptor (/mnt/c/Users/pas/dev/admin-app/.yarn/releases/yarn-sources.js:48444:26)
    at /mnt/c/Users/pas/dev/admin-app/.yarn/releases/yarn-sources.js:84576:31
    at Array.map (<anonymous>)
    at AddCommand.execute (/mnt/c/Users/pas/dev/admin-app/.yarn/releases/yarn-sources.js:84571:60)
    at async AddCommand.validateAndExecute (/mnt/c/Users/pas/dev/admin-app/.yarn/releases/yarn-sources.js:55036:26)
    at async Cli.run (/mnt/c/Users/pas/dev/admin-app/.yarn/releases/yarn-sources.js:51907:24)
    at async Cli.runExit (/mnt/c/Users/pas/dev/admin-app/.yarn/releases/yarn-sources.js:51916:28)

To Reproduce
yarn add <git remote URL> e.g.:
yarn add https://github.com/fancyapps/fancybox

Environment if relevant (please complete the following information):

• Node version v12.13.0
• Yarn version 2.0.0-rc.29.git.20200223.fbd94ea8

Manually specify the package name: yarn add fancybox@fancyapps/fancybox

[flymans]

Manually specify the package name: yarn add fancybox@fancyapps/fancybox

The problem is, I still can't add dependency from my gitlab private repository.
The same error - Invalid descriptor.

Invalid descriptor is a syntax error. If you don't print the command line, I can't tell you more than that 🙂

yarn add git+ssh://<git remote URL>#semver:^3.2.0

Looks like the specific issue arises here:
https://github.com/yarnpkg/berry/blob/master/packages/yarnpkg-core/sources/structUtils.ts#L194-L196
The regex doesn't seem to match any of the patterns in the docs.

I cheated by using npm followed by yarn install but it still seemed unable to resolve the pattern. I gave up and went back to v1.23

You're missing the package name:

yarn add <package name>@git+ssh://<git remote URL>#semver:^3.2.0

We only infer the package name from local directories at the moment.

My installation freezes:

laradock@3edd7fd0dc0c:/var/www/sogl$ yarn add lightGallery@github:sachinchoolur/lightGallery -D

Also add commant don't support --verbose option...

The Macintosh is warming up a lot, but nothing happens...

I have tried the above sample but I'm getting the following error:
error Can't add "<package-name>": invalid package version "1.0"
My package is on my company's GitLab repo. The version on the package.json is 1.0.
Do I need to make the version number contain three digits?
