npm install packagename --save-dev not updating package.json
提问by Brian Muenzenmeyer
Are there simple or subtle reasons that package.jsonwould not update after running a --save-dev? This is my command:
是否有简单或微妙的原因package.json在运行 --save-dev 后不会更新？这是我的命令：
npm install modulename --save-dev
npm install modulename --save-dev
Run from the root of the project. The command succeeds, the new module shows up in the node_modules directory as expected. Help would be appreciated. I am using npm v 1.4.28
从项目的根运行。命令成功，新模块按预期显示在 node_modules 目录中。帮助将不胜感激。我正在使用 npm v 1.4.28
The entirety of my current package.jsonis:
我目前的全部情况package.json是：
{
"name": "FooWeb",
"version": "1.0.0",
"description": "Foo Web",
"devDependencies": {
"gulp": "3.8.11",
"gulp-jshint": "1.9.2",
"gulp-concat": "2.5.2",
"gulp-sass": "1.3.3",
"gulp-sourcemaps": "1.4.0",
"gulp-watch": "4.1.1"
}
}
I do get warnings on install of a package that I have no repository field or README, but I think that is not related.
我确实在安装没有存储库字段或自述文件的软件包时收到警告，但我认为这不相关。

I had this problem as well, and it was driving me crazy.
我也有这个问题，这让我发疯。
What finally fixed it was running npm init. This added a bunch of stuff to my package.json, but afterwards --save-devworked as expected. Even after I removed all the new stuff added by npm init, --save-devstill worked.
最终修复它的是运行npm init。这在我的 package.json 中添加了一堆东西，但后来--save-dev按预期工作。即使在我删除了添加的所有新内容之后npm init，--save-dev仍然有效。

This can occur in VSCode (or probably other editors) if you have an unsaved package.jsonopen.
如果您package.json打开了未保存的文件，这可能会发生在 VSCode（或可能是其他编辑器）中。
The file wasactually being updated but not reloaded in the IDE. I think maybe the default is to reload only if the file is unedited? Or maybe I clicked something to ignore warnings.
该文件是实际被更新，但在IDE中没有重新加载。我想也许默认值是仅在文件未编辑时重新加载？或者也许我点击了一些东西来忽略警告。

I ran into this recently, and figured out that for whatever reason it was Atom that was preventing the file from updating, even without the file being open.
我最近遇到了这个问题，并发现无论出于何种原因，即使文件没有打开，也是 Atom 阻止了文件更新。
I closed the editor, re-ran my npm install, opened the editor again and everything was as it should be.
我关闭了编辑器，重新运行我的 npm 安装，再次打开编辑器，一切都应该如此。

Mustafah ELBanna's answer helped me, but i want to expand his answer for other newbies like myself. Please correct me if I miss something important.
Mustafah ELBanna 的回答对我有所帮助，但我想为像我这样的其他新手扩展他的回答。如果我错过了重要的事情，请纠正我。
If you remove the -gflag, the module is not installed globally for your machine, but only locally in your project. If you also want it to install globally, execute the same command again but now with -ginstead of --save-devlike this :
如果您删除该-g标志，则该模块不会在您的机器上全局安装，而只会在您的项目中本地安装。如果您还希望它全局安装，请再次执行相同的命令，但现在使用-g而不是--save-dev这样：
npm install --save-dev [packagename]
npm install --save-dev [packagename]
npm install -g [packagename]
npm install -g [packagename]
It seems to me that something might go wrong when calling -gand --savein one line.
在我看来，呼叫-g和--save一行时可能会出现问题。
But again, I'm new to this and I appreciate anyone who wants to improve/correct my answer.
但同样，我是新手，我感谢任何想要改进/纠正我的答案的人。

I was trying to install the gruntjs using "npm install --save grunt-sass" but the package.json won't update
我试图使用“npm install --save grunt-sass”安装 gruntjs，但 package.json 不会更新
I did everything mentioned above but no luck. But funny thing is if i try adding a package say "underscore (npm install --save underscore)" the son gets updated. I am not sure if this is a problem with the nam as such. I did install as a super user.
我做了上面提到的一切，但没有运气。但有趣的是，如果我尝试添加一个包，说“下划线（npm install --save underscore）”，儿子就会更新。我不确定这是否是 nam 本身的问题。我确实以超级用户身份安装。

You may first want to check your config (npm config lscommand or ~/.npmrcfile).
I had link=true.
您可能首先要检查您的配置（npm config ls命令或~/.npmrc文件）。我有link=true。
In version 5.5.1, this option seems to be ignored when --saveis active. Given that --save-devsupersedes --save, the link modeis active again.
在 5.5.1 版本中，当--save处于活动状态时，此选项似乎被忽略。鉴于--save-dev取代--save，链接模式再次处于活动状态。
So for me things happens as if --saveoverrided --linkwhich in turn overrided --save-dev.
所以对我来说，事情好像被--save覆盖了--link，然后又被覆盖了--save-dev。

I had the same problem. When i installed some package, it was not shown on the package.json. So then I deleted the package.json file and ran npm init again. After that it was working and the packages I installed before was also there under dependencies.
我有同样的问题。当我安装一些包时，它没有显示在 package.json 上。然后我删除了 package.json 文件并再次运行 npm init 。之后它就可以工作了，我之前安装的软件包也在依赖项下。
