Npm 更新不执行任何操作

当我在 package.json 所在的应用程序文件夹中执行这段代码时:

它不做任何事情。

但当我做 npm outdated是显示许多过时的软件包。

那么我如何更新所有的软件包呢？

OS: Win 10 x64
nodejs: 6.2.2
npm:3.10.7


package.json

运行 npm update --dd会产生以下提取输出:

最佳答案

The npm update --dd output says why at the end:

...not updating @angular/common because it's currently at the maximum version that matches its specified semver range

Look at this specific package, angular/common. You have it set to 2.0.0, which means npm will always fetch that specific version. If you want the package to update, you need to use a semver range. You can view a comprehensive list of semver ranges here, but the most commonly used are probably ~ and ^.

~ means that the patch version will update. So if you have version ~1.2.1, it will update to any 1.2.x, but never to 1.3.0.

^ updates the minor version, so if you have ^1.2.1, it will update to any 1.x.x release, but never to 2.0.0.

If npm [-g] outdated shows outdated packages outside of the semver range (e.g. a major update), the update command cannot be used to update these packages.

To install the latest version, explicitly specify the package with

npm install [-g] <package>

One more thing to check that could be affecting the way you install packages and ultimately causing this problem is your .npmrc file. Check to see if it has a line like:

save-exact=true

If it does, then remove it or set it to false. When it is set to true, you get the following behavior:

Dependencies saved to package.json using --save, --save-dev or --save-optional will be configured with an exact version rather than using npm’s default semver range operator.

.npmrc and save-exact

When I was very new to Node.js I didn't knew the following. I'm sharing if it might help you.

npm version:

npm --version

Note that following also checks for npm version:

npm --version <packagename> // package name argument is simply ignored

Package version:

npm list // at local directory to check local package versions
npm list -g // to check global package versions

To update, here are the steps:

Running npm outdated will allow you to check all the packages that need to be updated. The list will show current, wanted and latest version of each package.
Next, run npm update which will update all the packages to the latest possible version as defined in package.json. For example, if a certain package in package.json has version ^2.3.1 then this package will not be updated beyond 2.x.x, and if a package has version ~5.3.2 then it will not be updated beyond 5.3.x. (to understand semantic versioning, read this)
But what if you want to update to the latest, and the versions of your packages in package.json are preventing you from updating as described in step 2 above? Well there are two solutions.

a) You can manually update the package versions in package.json by changing the versions of your packages to the latest values you like them to be. Although this might work, this is very tedious and error prone. So I do not recommend it.

b) You can automatically update the versions of your packages in package.json. To do so, you need to install the npm-check-updates package (I typically install this package globally) using this command: npm i -g npm-check-updates. Once this is done, you have to run ncu -u. This will only update the package versions in package.json to the latest version. You may be requested to run npm install to install the latest version available. I recommend this method.
Now, after updating the versions of your packages in package.json, run npm update and your packages will be updated to the latest version.

Update all outdated packages to latest version with one liner on bash

npm outdated | cut -d" " -f1 | tail -n +2 | sed 's/$/@latest/' | xargs npm i

If you are using ^ or ~ or in front of your versions, then you cannot get the next major version of that package with npm update <package-name>. You could check your outdated packages using npm outdated and run npm install <package-name>@latest for each of them, the above one liner will do all this for you

You can force update all packages even if it breaks semantic versioning using an existing package.

Use this with care for important projects and absolutely avoid in production.

I find this shortcut useful for personal projects.

This package will update all the dependency versions in package.json and the following install command with install them.

npx npm-check-updates -u && npm i
