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……

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.
