javascript - 无法在 mac 上的 Meanjs 现有项目中找到本地 grunt

Question

我想在我的 mac 电脑上运行我从 friend 那里得到的meanjs现有项目，但是当我运行“grunt”命令时，出现以下错误:

grunt-cli: The grunt command line interface. (v0.1.13)

Fatal error: Unable to find local grunt.

搜索谷歌后我使用了下面这两个命令:

sudo npm install grunt --save-dev

npm install

但出现以下错误:

Loading "gruntfile.js" tasks...ERROR
>> Error: Cannot find module 'load-grunt-tasks'
Warning: Task "default" not found. Use --force to continue.

Aborted due to warnings.

[注意:但是 grunt 正在为我本地 Mac 上新创建的meanjs 项目工作，但不适用于我 friend 的这个旧项目]

更新 - 我这里有 package.json 文件:

有人可以帮我吗？

Node.js 项目如果与 npm 一起使用，则必须附带 package.json 文件。package.json ( https://docs.npmjs.com/files/package.json ) 文件包含有关项目的所有信息，甚至是依赖项(使用 --save 添加)。

因此，如果您的 friend 所做的一切正确，您只需运行 npm install 即可安装所有依赖项。如果没有 package.json 文件或者上面没有写入依赖项，则必须手动安装它们。

grunt 有许多模块可以工作，其中一个称为 load-grunt-tasks 所以你应该再次运行 npm install load-grunt-tasks --save-dev 当然，这只是在文件中没有依赖项的情况下。
