Update local file dependency with npm

问题:

I have a project with a local file dependency in my package.json like this:

"dependencies": {
    "dep_1": "file:../../dep_1"
  }
}

When I do npm install it is installed into node_modules. But if I make changes to dep_1 how do I update the module version in node_modules?

I tried doing npm update but nothing happens.

If you are using a relatively new version of npm (I used version 2.14.2) you can bump the version number in package.json and npm update dep_1 should work. Otherwise how can npm know that something needs to be updated?

Note: This will only work if the version is higher than what has previously been installed. You will have to clean the cache to reset this behaviour.

However, you can forceably (and lazily) update local modules by simply running npm install again. e.g.

npm install dep_1

It should be fast since its on your local computer and you don't have to play around with version numbers.
