我试图在 Gulp 任务中使用Wiredep在我的 index.html 文件中注入 Bower 依赖项。以下任务(没有Wiredep)运行良好。
gulp.task('build', ['copy', 'assets'], function(){
return gulp.src('app/index.html')
.pipe(inject(gulp.src(['dist/assets/js/*.js', 'dist/assets/css/*.css'], {read: false}), {relative: true}))
.pipe(gulp.dest('dist'));
});
现在我尝试将Wiredep添加到它:
var wiredep = require('wiredep');
gulp.task('build', ['copy', 'assets'], function(){
return gulp.src('app/index.html')
.pipe(wiredep())
.pipe(inject(gulp.src(['dist/assets/js/*.js', 'dist/assets/css/*.css'], {read: false}), {relative: true}))
.pipe(gulp.dest('dist'));
});
结果是:

我尝试直接从命令行使用Wiredep,它运行良好。我在 Windows 上运行,使用 Node v4.2.2。
编辑 如果有人遇到同样的问题,那么解决方法是将任务更改为:
gulp.task('build', ['copy', 'assets'], function(){
wiredep({src:'dist/index.html'});
return gulp.src('dist/index.html')
.pipe(inject(gulp.src(['dist/assets/js/*.js', 'dist/assets/css/*.css'], {read: false}), {relative: true}))
.pipe(gulp.dest('dist'));
});
请注意,index.html 在 beeing 注入之前被复制到 dist 目录。
我仍然想知道为什么我不能使用流来连接依赖项。
