Question

我正在尝试在节点项目上安装npm软件包，但是无论我做什么，该模块都会继续在全局安装。

我当前的目录为D:\wrkfldr\NodeTemp，其中包含package.json：

{
  "name": "nodetemp",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

如果我运行npm install websocket，则package.json保持不变，并且模块已在C:\Users\Me\AppData\Roaming\npm\node_modules中全局安装

在安装软件包时，我收到以下消息：

PS D:\wrkfldr\NodeTemp> npm install websocket

> websocket@1.0.28 install C:\Users\Me\AppData\Roaming\npm\node_modules\websocket
> (node-gyp rebuild 2> builderror.log) || (exit 0)


C:\Users\Me\AppData\Roaming\npm\node_modules\websocket>if not defined npm_config_node_gyp (node "C:\Program Files\nodejs\node_modules\npm\node_modules\npm-lifecycle\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild )  else (node "C:\Program Files\nodejs\node_modules\npm\node_modules\node-gyp\bin\node-gyp.js" rebuild )
+ websocket@1.0.28
added 7 packages from 15 contributors in 5.812s

我正在Windows下工作，并且刚刚删除/重新安装了节点，但是并不能解决问题。

如何获取软件包以在本地安装？

注意：如果我在package.json中手动添加依赖项，然后运行npm install，则它可以正常工作，目录node_modules已创建，并且导入工作正常。

这是我的npm-config ls -l

您安装软件包的默认设置被覆盖。运行命令npm config ls -l时，可以按格式; key = default_value (overridden)来识别被覆盖的值。当您运行上述命令时，被覆盖的值也位于输出的顶部。它将显示如下内容：

; cli configs
    (...)

; userconfig C:\Users\Me\.npmrc
    global = true ---> here you can see it is overridden

; globalconfig /path/to/global/config/file
    (...) ----> if you got globally overridden default values, you see those values here


; default values
    (...)
; global = false (overridden) --> here you can see what the default value is
    (...)

在您的情况下，global的值在C:\Users\Me\.npmrc中被覆盖（如果您将其去离子化，则将其更改为实际路径）。打开该文件并删除global = true行。您也可以使用npm-config CLI，但是我的经验是，这种方法并不总是有效。

删除该行之后，再次运行npm config ls -l，以验证配置是否恢复为默认值。

即使在npm init之后，npm仍会全局安装软件包
