reactjs – Browserify无法使用babelify变换创建包(TypeError：Path必须是字符串.)

我编写了一个gulp任务,使用watchify和babelify作为转换将我的.jsx和.js脚本编译成一个包.出于某种原因,我的gulp脚本似乎对变换感到窒息,我不知道为什么：

gulp.task('browserify',function() {
  var bundle = watchify(browserify('./app/jsx/client/index.jsx',{
    extensions: ['.js','.jsx'],debug: process.env.NODE_ENV === 'development'
  }));
  bundle.transform(babelify);
  bundle.on('update',function() {
    rebundle(bundle);
  });


  function rebundle(bundle) {
    return bundle.bundle()
    .on('error',function(error) {
      console.log(error.stack,error.message);
      this.emit('end');
    })
    .pipe(
        gulpif(
          (process.env.NODE_ENV == 'production'),require('gulp-rename')('bundle.min.js'),require('gulp-rename')('bundle.js')
        )
    )
    .pipe(gulpif((process.env.NODE_ENV == 'production'),buffer()))
    .pipe(gulpif((process.env.NODE_ENV == 'production'),uglify()))
    .pipe(gulp.dest('dist/js'));
  }

  return rebundle(bundle);
});

在控制台……

    throw new TypeError('Path must be a string. Received ' +
    ^

解决方法

那个错误是因为你需要一个 vinyl-source-stream. .bundle()的结果是文件数据的标准节点流.您正在将数据传递给重命名,这需要Gulp File对象流.

var source = require('vinyl-source-stream');

// stuff

  function rebundle(bundle) {
    return bundle.bundle()
    .on('error',// Use 'source' here instead,which converts binary
          // streams to file streams.
          source('bundle.min.js'),source('bundle.js')
        )
    )
    .pipe(gulpif((process.env.NODE_ENV == 'production'),uglify()))
    .pipe(gulp.dest('dist/js'));
  }

您可以使用source来定义文件的初始名称,而不是使用重命名.
