I am wondering if it is possible to run a command that would check that the package is a valid npm package, add it to package.json as a dependency, but not install it.
我想知道是否可以运行一个命令来检查包是否是一个有效的npm包，将它作为依赖项添加到package.json，但不安装它。
I am doing this because I have a certain package installed globally and need to require it for an open source project. Hence, I wish it to be included.
我这样做是因为我在全局安装了某个软件包，并且需要为开源项目提供它。因此，我希望它被包括在内。

I don't think yo can do that with npm. I've looked into the docs and I didn't find anything about.
我不认为你可以用npm做到这一点。我查看了文档，但没有找到任何相关信息。
You can use this as a workarround:
您可以将其用作工作场所：
npm i <package> --save && npm uninstall <package>
Hope it helps.

The correct way to only update package.json, without any other side-effects is:
只更新package.json而没有任何其他副作用的正确方法是：
npm install --save --package-lock-only --no-package-lock <package>
Use --package-lock-only to prevent writing to node_modules.
使用--package-lock-only防止写入node_modules。
The --package-lock-only argument will only update the package-lock.json, instead of checking node_modules and downloading dependencies.
--package-lock-only参数只会更新package-lock.json，而不是检查node_modules和下载依赖项。
Then, use --no-package-lock to prevent the creation of the lock file:
然后，使用--no-package-lock来防止创建锁定文件：
The --no-package-lock argument will prevent npm from creating a package-lock.json file. When running with package-lock's disabled npm will not automatically prune your node modules when installing.
--no-package-lock参数将阻止npm创建package-lock.json文件。在使用package-lock运行时，npm在安装时不会自动修剪节点模块。
See npm install docs for more.

If your package is installed globally, I don't know if npm would reinstall it if you run:
如果您的软件包是全局安装的，我不知道如果运行，npm是否会重新安装它：
npm install --save foobar
npm install --save foobar
That's what I would do to add it to the package.json
这就是我要把它添加到package.json中的方法
