我有一个现有的项目,我使用了React 16.9
. 现在,我想实现Gulp 4.0.1
在服务器中构建它。我在 Windows 10 中运行。
在我的组件中,我正在使用import
form
我尝试使用这个 gulpfile.js,它非常简单。
var gulp = require('gulp'),
browserify = require('browserify'),
source = require('vinyl-source-stream'),
buffer = require('vinyl-buffer');
var BUILD_DIR = 'buildtest/';
function compile() {
var bundler = browserify('src/index.js');
return bundler
.transform('babelify', { presets: ['es2015', 'react'] })
.bundle()
.pipe(source('index.js'))
.pipe(buffer())
.pipe(gulp.dest(BUILD_DIR));
}
gulp.task('build:js', function() {
return compile();
})
gulp.task('build', ['build:js'])
现在通过运行gulp
命令它给了我这个错误:
λ gulp
assert.js:350
throw err;
^
