node.js - npm 错误!缺少脚本 : build when deploying react app to heroku

Question

我制作了一些小型的 React Web 应用程序，我正在尝试将其部署到 Heroku。我找到了这个https://github.com/mars/create-react-app-buildpack通过 youTube 视频，据说这是一种简单的部署方法。作者列出了几个步骤(前两个不适用):

1. git 初始化
2. heroku 创建 $APP_NAME --buildpack https://github.com/mars/create-react-app-buildpack.git
3. git 添加。
4. git commit -m“从create-react-app开始”
5. git push heroku master
6. heroku 打开

一旦我到达 git Push heroku master，我就会在控制台中收到一个错误:

npm ERR! missing script: build
remote:
remote: npm ERR! A complete log of this run can be found in:
remote: npm ERR!     /app/.npm/_logs/2018-03-26T16_55_19_748Z-debug.log

 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/my-simple-react-weather-app.git'

我做了一些搜索，找到了一些适合我的 package.json 文件的构建脚本，但它们似乎都不起作用 (""build": "webpack --config webpack.conf.js"")

这是我的 package.json:

{
  "name": "redux-simple-starter",
  "version": "1.0.0",
  "description": "Simple React YouTube App",
  "main": "index.js",
  "scripts": {
    "start": "node ./node_modules/webpack-dev-server/bin/webpack-dev-server.js",
    "test": "mocha --compilers js:babel-core/register --require ./test/test_helper.js --recursive ./test",
    "test:watch": "npm run test -- --watch"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-core": "^6.2.1",
    "babel-loader": "^6.2.0",
    "babel-preset-es2015": "^6.1.18",
    "babel-preset-react": "^6.1.18",
    "chai": "^3.5.0",
    "chai-jquery": "^2.0.0",
    "jquery": "^2.2.1",
    "jsdom": "^8.1.0",
    "mocha": "^2.4.5",
    "react-addons-test-utils": "^0.14.7",
    "webpack": "^1.12.9",
    "webpack-dev-server": "^1.14.0"
  },
  "dependencies": {
    "babel-preset-stage-1": "^6.1.18",
    "lodash": "^3.10.1",
    "react": "^0.14.3",
    "react-dom": "^0.14.3",
    "react-redux": "4.3.0",
    "react-router": "^2.0.1",
    "redux": "^3.0.4",
    "youtube-api-search": "0.0.5"
  }
}

有人可以帮我吗？我已经登录到我的 heroku 帐户。有没有比我在这里做的更简单的方法？

Answer 1

如果您提供 git 存储库，它可能有助于快速解决问题，但现在请确保您已安装

react 脚本

npm i react-scripts --save-dev

确保 -dev 存在，以便它在服务器启动之前运行 for more details

另外，请让您的客户端(react app)package.json 包含相同的内容

"scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"

确保您使用正确的构建包也非常重要如果它唯一的 react 应用程序没有node.js for more details

heroku create $APP_NAME --buildpack mars/create-react-app

但是如果你使用 Node.js 构建 Dual

heroku buildpacks:clear
