试图运行babel：“找不到模块@babel/Core”

Question

我试图建立一个构建环境来探索React。我的构建过程使用GULP。

我这样安装了软件包：

npm安装--save-dev@babel/preset-react

我的.Babelrc有这个：

{“预置”:[“@Babel/Preset-React”]}

gulp.task('scripts', function() {
    return gulp.src(['./src/js/main.js' ])
        .pipe(babel({
            presets : ['@babel/preset/react']
        }))
        .pipe(concat('test.js'))
        .pipe(gulp.dest('./js'))
        .pipe(uglify())
        .pipe(rename('test.min.js'))
        .pipe(gulp.dest('./js')) ;
});

[22:51:14] Using gulpfile ~/play/learning-react-2/gulpfile.js
[22:51:14] Starting 'scripts'...
[22:51:14] 'scripts' errored after 59 ms
[22:51:14] Error in plugin "gulp-babel"
Message:
    Cannot find module '@babel/core' (While processing preset: "/home/bob/play/learning-react-2/node_modules/@babel/preset-react/lib/index.js")

npm安装--save-dev@babel/core

如果我查看node_modules的内容，我会看到这些与Babel相关的包：

babel-plugin-transform-regenerator/

babel-transform-runtime/

我猜其中至少有一个是“巴别塔核心”

所以...我如何从Gulp中运行babel？我怎么运行它？

我也有同样的问题。我通过删除node_modules和重新安装包（使用yarn或npm install)来解决这个问题。问题解决了。
