npm install packagename --save-dev不更新package.json [英] npm install packagename --save-dev not updating package.json

问题描述

是否有简单或微妙的原因导致 package.json 在运行--save-dev后不会更新？这是我的命令：

Are there simple or subtle reasons that package.json would not update after running a --save-dev? This is my command:

npm install modulename --save-dev

从项目的根目录运行。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

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

我当前的 package.json 的全部是：

{
    "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"
    }
}

我在安装没有存储库字段或自述文件的软件包时收到警告，但我认为这没有关系。

I do get warnings on install of a package that I have no repository field or README, but I think that is not related.

推荐答案

我也遇到了这个问题，这让我发疯。

I had this problem as well, and it was driving me crazy.

最终解决的问题是运行 npm init 。这给我的package.json添加了很多东西，但是随后-save-dev 可以正常工作。即使我删除了 npm init 添加的所有新内容之后，-save-dev 仍然有效。

What finally fixed it was running npm init. This added a bunch of stuff to my package.json, but afterwards --save-dev worked as expected. Even after I removed all the new stuff added by npm init, --save-dev still worked.
