如何在ReactJS中添加Gulp？运行遇语法错误及相关疑问求助

Hey there! Let's break down your questions one by one:

1. Fixing the JSX Syntax Error in App.js #

That error pops up because your Babel setup isn't configured to parse JSX syntax. Since you used create-react-app to bootstrap your project, it already has a pre-configured Babel setup that handles JSX out of the box—but when you added a custom .babelrc file, you overrode that default configuration, and your custom setup is missing the React preset needed to process JSX.

Here are two solid fixes:

• Option 1: Stick with create-react-app's default setup
  Remove your custom .babelrc file. create-react-app manages Babel and Webpack configs internally, so you don't need to manually add these files unless you eject the project. If you want to use Gulp alongside it, make sure your Gulp tasks don't interfere with the existing build pipeline.
• Option 2: Configure Babel for JSX in your Gulp setup
  If you want to keep using your custom .babelrc and Gulp, install the required React preset first:

  npm install --save-dev @babel/preset-react
  

  Then update your .babelrc to include the preset:

  {
    "presets": ["@babel/preset-react"]
  }
  

  Also, double-check your Gulp task to ensure it's using gulp-babel to transpile your JSX files correctly.

2. What does npm run gulp do? #

When you run npm run gulp, npm looks into your project's package.json file, finds the scripts section, and executes the command linked to the "gulp" key.

For example, if your package.json has:

{
  "scripts": {
    "gulp": "gulp"
  }
}

This runs the gulp command (using your local project's installed Gulp, not the global one by default), which loads your gulpfile.js and runs the default task defined in it (or any specific task you've specified in the script, like "gulp": "gulp build").

3. Will the project keep running after exiting the terminal with nohup? #

Absolutely! The nohup command is built to let processes keep running even after you log out or close the terminal. When you run something like:

nohup npm run gulp &

The & sends the process to the background, and nohup ensures it isn't terminated when your shell session ends. The process will keep running until it finishes its task, hits an error, or you manually kill it (using kill or pkill commands).
