I need to setup ReactJS on my Mac. I have npm version of 4.1.2 and node version of v7.7.4. I clone the project from Git and in the project folder trying to execute npm install and following npm start. But I get error. I removed&uninstalled node and npm and then re-installed with homebrew, but it did not help. Here is the screen of error I get in terminal? Do you have any idea what is the problem?

这是我的 package.json 文件

{
  "name": "viaopt",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {},
  "devDependencies": {
    "webpack": "^2.3.0"
  },
  "description": ""
}

推荐答案

从您显示的错误中，我可以看出您的 package.json 文件中没有 start 脚本.要使 npm start 工作，package.jsonscripts 属性下的 start 键下应该有一个命令> 文件.

From the error you are showing I can tell that there is no start script in your package.json file. For npm start to work there should be a command under the start key under the scripts attribute in your package.json file.

当您运行 npm start 时，npm 在 package.json 中查找并运行 start 值下列出的任何内容.

When you run npm start npm looks in package.json and runs whatever is listed there under the start value.

我猜你的项目配置了 gulp 或 webpack?

I'm guessing you have gulp or webpack configured with your project?

尝试在您的终端中运行 webpack，看看您的项目是否启动.

Try running webpack in your terminal and see if your project fires up or smth.

希望这会有所帮助.干杯.

Hopes this helps. Cheers.
