Question

我的旧Mac上有一个使用npm和node的项目。当我更换计算机时，我将文件复制到新的mac中，并运行npm install，然后尝试使用browserify运行脚本，该脚本将转换ES6的代码。我一直收到错误

Error: Cannot find module './args'

我认为它不是一个模块。我也试图单独重新安装主要模块，但错误仍在继续。问题：当它说“找不到模块'./args'时，它是什么意思？我该如何解决这个错误？

 "scripts": {
    "build-js": "browserify app/app.js app/goopy.js app/models.js app/goofy.js -t babelify > app/bundle.js"
  },

的package.json

"devDependencies": {
    "babelify": "^5.0.3",
    "bower": "^1.3.1",
    "http-server": "^0.6.1",
    "karma": "^0.12.31",
    "karma-junit-reporter": "^0.2.2",
    "protractor": "^1.1.1",
    "shelljs": "^0.2.6",
    "browserify": "latest",
    "watchify": "latest",
    "gulp": "latest",
    "vinyl-source-stream": "latest",
    "karma-phantomjs-launcher": "^0.1.4",
    "karma-qunit": "^0.1.4"
  },
  "dependencies": {
    "JSON2": "^0.1.0",
    "grunt": "^0.4.5",
    "grunt-contrib-watch": "^0.6.1",
    "gulp": "^3.8.11",
    "karma": "0.12.31",
    "qunit": "0.7.5",
    "requirejs": "^2.1.16",
    "sinon": "^1.12.2",
    "watchify": "^2.4.0"
  }

这是完整的错误消息

Error: Cannot find module './args'

    at Function.Module._load (module.js:278:25)

    at Function.Module.runMain (module.js:501:10)

更新以下是正在运行的输出

find . -name \*.js -exec grep -H "\./args" {} \;

注意，根据下面的输出，我对npm i，watchify和require进行了karma，但错误消息仍为

Answer 1

@avandeursen建议我运行这个命令

find . -name \*.js -exec grep -H "\./args" {} \;

在项目中找到require（＆＃39; / args＆＃39;）代码，并根据OP更新中的输出，重新安装browserify npm i browserify，现在错误消息消失了

Answer 2

复制项目时，最好从全新安装开始进行依赖：

删除目录
```
/node_modules/
```
输入您的终端
```
npm install
```
运行代码

错误：找不到模块'./args'
