npm update does not do anything
提问by Elisabeth
When I execute this code in my application folder where the package.json is located:
当我在 package.json 所在的应用程序文件夹中执行此代码时：
npm updateor npm update --save-devit does not do anything.
npm update或者npm update --save-dev它什么都不做。
But when I do npm outdatedis shows many outdated packages.
但是当我这样做时npm outdated会显示许多过时的软件包。
So how do I update all packages?
那么如何更新所有软件包呢？

The npm update --ddoutput says why at the end:
该npm update --dd输出为什么说在最后：
...not updating @angular/common because it's currently at the maximum version that matches its specified semver range
...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 ^.
看看这个特定的包，angular/common. 您将其设置为2.0.0，这意味着 npm将始终获取该特定版本。如果要更新包，则需要使用 semver 范围。您可以在此处查看 semver 范围的完整列表，但最常用的可能是~和^。
~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.
~表示补丁版本会更新。因此，如果您有版本~1.2.1，它将更新为 any 1.2.x，但永远不会更新1.3.0。
^updates the minor version, so if you have ^1.2.1, it will update to any 1.x.xrelease, but never to 2.0.0.
^更新次要版本，所以如果你有^1.2.1，它会更新到任何1.x.x版本，但永远不会更新到2.0.0.

If npm outdatedshows outdated packages outsideof the semver range (e.g. a major update), npm updatecannotbe used to update these packages.
如果npm outdated显示超出semver 范围的过时包（例如重大更新），npm update则不能用于更新这些包。
To install the latest version, explicitly specify the package with
要安装最新版本，请明确指定包
npm install [-g] <package>

When I was very new to Node.js I didn't knew the following. I'm sharing if it might help you.
当我刚接触 Node.js 时，我不知道以下内容。如果它对你有帮助，我正在分享。
npm version:
npm 版本：
npm --version
Note that following also checks for npm version:
请注意，以下还会检查 npm 版本：

npm list -g // to check global package versions

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:
要检查的另一件事可能会影响您安装软件包的方式并最终导致此问题是您的 .npmrc 文件。检查它是否有如下一行：

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.
使用 --save、--save-dev 或 --save-optional 保存到 package.json 的依赖项将被配置为一个确切的版本，而不是使用 npm 的默认 semver 范围运算符。
