Browserify 无法使用 babelify 转换创建包(TypeError:路径必须是字符串.) [英] Browserify fails to create bundle with babelify transform (TypeError: Path must be a string.)
问题描述
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 脚本似乎在转换时卡住了,我不确定为什么:
I've written a gulp task to compile my .jsx and .js scripts into a bundle using watchify and babelify as a transform. For some reason my gulp script seems to be choking on the transform and I'm not sure why:
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);
});
在控制台中...

推荐答案
那个错误是因为你需要一个 vinyl-source-stream
在那里..bundle()
的结果是一个标准的 Node 文件数据流.您正在将该数据传递给 rename
,它需要 Gulp File
对象流.
That error is because you need a vinyl-source-stream
in there. The result of .bundle()
is a standard Node stream of file data. You are taking that data are passing it to rename
which expects a stream of Gulp File
objects.
var source = require('vinyl-source-stream');
// stuff
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'),
// 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'), buffer()))
.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rename
.
Instead of using rename
, you can use source
to define the initial name of the file.
