How to install package with local path by Yarn? It couldn't find package

In my

I'm pointing local package
by its relative path:


"dependencies": {
"core-js": "^2.4.1",
"my-custom-i18n": "./../MyProject.Shared/myproject-i18n",
"rxjs": "5.0.0-beta.12",

npm install
installs packages correctly, but
has problem with it and simply cannot find this package:

yarn output

$ yarn
yarn install v0.15.1
info No lockfile found.
[1/4] Resolving packages...
error Couldn't find package "myproject-i18n" on the "npm" registry.
info Visit http://yarnpkg.com/en/docs/cli/install for documentation about this command.

I see that it looks it on the
registry, where this package doesn't live.


Is there any change to use yarn with local packages?
By local packages I mean packages pointed by relative path as

Answer Source

Yarn requires prefix file: for local packages.

For relative path:

yarn add file:./../your-project

For absolute path

yarn add file:/dev/your-project

For your example, dependency in package.json would be declared as follows:

 "my-custom-i18n": "file:./../MyProject.Shared/myproject-i18n",

This works both for Yarn and NPM as well.

It is incompatibility with NPM client, Yarn team is aware and declared to support this behavior - reference on GitHub issue.
