How to install package from github repo in Yarn

When I use npm install fancyapps/fancybox#v2.6.1 --save, so fancybox package at v2.6.1 tag will be installed. This behavior is described in docs

I want to ask, how to do this with yarn?

Is this command the right alternative? In yarn docs isn't anything about this format.

yarn add fancyapps/fancybox#v2.6.1

You can add any Git repository (or tarball) as a dependency to yarn by specifying the remote URL (either HTTPS or SSH):

yarn add <git remote url> installs a package from a remote git repository.
yarn add <git remote url>#<branch/commit/tag> installs a package from a remote git repository at specific git branch, git commit or git tag.
yarn add https://my-project.org/package.tgz installs a package from a remote gzipped tarball.

Here are some examples:

yarn add https://github.com/fancyapps/fancybox [remote url]
yarn add ssh://github.com/fancyapps/fancybox#3.0  [branch]
yarn add https://github.com/fancyapps/fancybox#5cda5b529ce3fb6c167a55d42ee5a316e921d95f [commit]

(Note: Fancybox v2.6.1 isn't available in the Git version.)

To support both npm and yarn, you can use the git+url syntax:

git+https://github.com/owner/package.git#commithashortagorbranch
git+ssh://github.com/owner/package.git#commithashortagorbranch

For ssh style urls just add ssh before the url:

yarn add ssh://<whatever>@<xxx>#<branch,tag,commit>
