通过指定远程URL(HTTPS或SSH)，可以将任何Git存储库(或tarball)作为依赖项添加到yarn:
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.
以下是一些例子:
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.)
要同时支持npm和Thread，可以使用git+url语法:
git+https://github.com/owner/package.git#commithashortagorbranch
git+ssh://github.com/owner/package.git#commithashortagorbranch
