heroku - heroku 上没有安装 node_modules

Question

下面是两个包，我试图用它们将我的项目推送到 heroku，控制台说 npm 和节点安装在服务器上但是当我克隆项目时，项目中没有 node_modules 目录。 package.json 中的“bower install”表示未找到 bower。当我删除“bower install”时，推送时服务器上没有安装任何依赖项，尽管控制台将它们记录为已安装，但当我打开浏览器控制台时，它们并未安装在服务器上。

package.json:

{
  "name": "meal-order",
  "version": "0.0.0",
  "description": "This is an app for ordering meal",
  "main": "gulpfile.js",
  "dependencies": {
    "angular": "^1.5.5",
    .....(other angular -libs)
    "express": "^4.14.0",
    "gulp": "^3.8.8",
    "gulp-connect": "^3.0.9",
    "ionicons": "^3.0.0",
    "protractor": "^3.3.0"
  },
  "devDependencies": {
      "bower": "1.7.7"
  },
  "engines": {
    "node": "^5.11.1",
    "npm": "^3.8.6"
  },
  "scripts": {
     "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node index.js",
    "postinstall": "bower install"
  },

bower.json:

"dependencies": {
"angular": "^1.5.5",
.....(other angular -libs)
"express": "^4.14.0",
"gulp": "^3.8.8",
"gulp-connect": "^3.0.9",
"ionicons": "^3.0.0",
"protractor": "^3.3.0"
},
"devDependencies": {},
"main": "gulpfile.js",
"license": "ISC",
"moduleType": [
    "node"
],

.gitignore:

/node_modules/*
node_modules/*
node_modules
npm-debug.log

这是我在控制台上得到的错误:

remote:        Skipping cache restore (new runtime signature)

remote:        > bower install
remote:

Answer 1

这是因为您在 package.json 的 devDependencies 对象中定义了 bower。当你推送到 Heroku 时，它不会安装 devDependencies 中列出的东西，所以你需要在你的普通 dependencies 对象中列出 bower =)
