Question

我正在学习nodejs并尝试构建一个简单的控制台应用程序。该应用程序正在运行但是，当我运行下面的package.json，以便我可以轻松地构建它并安装所有依赖项时，会出现一些错误。看起来它无法安装依赖项，因为如果我首先安装了依赖项，那么就不会有问题。有谁知道我的package.json有什么问题？

感谢。

    "build-js": "browserify scripts/app.js > scripts/bundle.js"
  },
  "dependencies": {
    "browserify": "*",
    "uniq": "*"
  }
}

当我运行npm run build-js时，我收到以下错误：

在运行npm install之前，我是否必须首先运行npm run build-js来安装所有依赖项？

Answer 1

我感觉这是导致问题的重定向（>），或者是因为命令在幕后执行的方式，或者是因为文件你是＆＃39 ;尝试将输出重定向到已存在。

您应该使用browserify --outfile / -o选项代替：

"scripts": {
    "build-js": "browserify scripts/app.js -o scripts/bundle.js"
},

npm - 运行package.json
