npm 没有按预期工作

Question

运行ning npm install from any directory having package.json 目前对我不起作用。我什至在一些知名项目上尝试过，但问题是一样的，所以我想这不是我搞砸了我的 package.json.

所以问题是，npm install 实际上在我的本地 node_modules 目录中安装了大约 241 个模块。虽然我在 package.json 中清楚地只列出了 3 个。 npm 行为突然一次又一次地安装，每次我运行它。

我以前使用相同的代码提交给 git 和 npm install 只是在我的 node_modules.[=23 中产生了 3 个包=]

$ npm -v
3.8.1

$ node -v
v5.8.0

Answer 1

npm 的这种行为已从版本 2 更改为版本 3 及更高版本：版本 2 和更早版本使用子文件夹。从版本 3 开始，您将获得扁平的包结构。因此，您现在看到的是之前作为 4 个依赖项的子文件夹 (node_modules) 提供的所有临时依赖项。

但是，最终的行为应该是完全一样的。
