如何在 NPM 中更新 devDependency？

npm update似乎只是更新了 dependencies中的软件包，但是 devDependencies呢。

现在您可以通过运行 npm install .来安装 devDependencies，但是这对 npm update .不起作用

有什么想法吗？

One (slow) way to do force the update, is to remove the node_modules directory, and then do npm install again.

This was a known bug of the npm update command, which has been fixed on the development branch of npm, see here: https://github.com/isaacs/npm/pull/3863

It should land on the latest stable version of npm pretty soon.

This problem does no longer excise with the current version of NPM (1.3.11).

Update works fine with: npm update

I ran into the same problem as OP had, and found no solution, so I decided to write a Grunt plugin that will auto-update my devDependencies..

It's on Github, I'd love to get some input and collaborations in order to make it the best tool that NPM hasn't provided.

Basically it will auto-update your outdated development dependencies with a simple Grunt Task.

To update package.json in addition to the local modules, run

npm update --save-dev

Alternatively, the same command to save time

npm update -D

You can view the full detail of update, or any command for that matter through

npm help <cmd>

Install npm-check-updates (https://www.npmjs.org/package/npm-check-updates), then jump into your project folder and run:

npm-check-updates

And to update and save changes to your package.json file:

npm-check-updates -u

If you are using outdated npm version it might be the problem. So before any other commands execute:

sudo npm install npm -g

or (if above doesn't work):

sudo npm update npm -g

Then relaunch the console (in order for changes to take effect). Now you can check your new npm --version and if it is up to date execute:

npm update

or (if you prefer):

npm update --save-dev

What worked for me is installing individual dev dependencies like this

npm install react-test-renderer@15.6.1 --save --only=dev

These steps worked for me :

  1. npm install -g npm-check-updates
  2. ncu -u
  3. npm update
  4. npm install

  1. npm outdated - for an overview what's outdated
  2. npm install -g npm-check-updates - as pointed correctly by Michael
  3. ncu -u - it'll automatically update all dependencies (also dependencies, i.e., it's of course different than devDependencies) versions in package.json, without reinstalling it yet. It'll just change the "numbers" in package.json
  4. npm update - actual dependencies installation
  5. (Optional, depending by scenario) you might need to use the flag --force, or (new in NPM v7) --legacy-peer-deps to complete the process. You can read about difference between those 2 on What does npm install --legacy-peer-deps do exactly? When is it recommended / What's a potential use case?
  6. (Optional) you can validate it using ncu -u and for correctly updated dependencies you should see the text All dependencies match the latest package versions :)
