Uglify抛出解析错误
Uglify抛出解析错误
提问于 2015-01-18 02:58:21
当我在browserify中使用gulp uglify时，我得到一个错误
events.js:72
throw er; // Unhandled 'error' event

entries: ['./src/scripts/main.js'],
debug: debug
}).transform(stringify()); // the error persist even without this transformation
bundler
.bundle()
.on('error', handleErrors)
.pipe(source(getBundleName() + '.js'))
.pipe(jshint())
.pipe(jshint.reporter('default', { verbose: true }))
.pipe(jshint.reporter('fail'))
.pipe(buffer())
.pipe(sourcemaps.init({loadMaps: true}))
.pipe(uglify())
.pipe(sourcemaps.write('./'))
.pipe(gulp.dest('./web/js'));

我在使用gulp-concat-sourcemap和gulp-uglify时遇到了同样的问题。我通过使用gulp-ignore忽略地图文件解决了这个问题
gulp.task("uglify-src", function() {
gulp.src([ "src/js/**/*.js" ])
.pipe(concat("app.js"))
.pipe(ignore.exclude([ "**/*.map" ]))
.pipe(uglify())
.pipe(gulp.dest("dist/js"));

uglify将在最小化脚本内容之前对其进行解析。我怀疑到uglify的流中包含了其中一个browserify源映射。无论如何，要找到问题，你可以使用gulp-util的log方法来处理uglify的异常。示例：
...
var gulpUtil = require('gulp-util');
gulp.task('scripts', function() {
...
.pipe(sourcemaps.init({loadMaps: true}))
.pipe(uglify().on('error', gulpUtil.log)) // notice the error event here
.pipe(sourcemaps.write('./'))
.pipe(gulp.dest('./web/js'));
});如果修复问题仍有问题，请在合并错误日志后发布详细信息。

这可能是源JavaScript文件中的一个简单错误。尝试通过在gulpfile中将其注释掉来禁用uglify，看看您的浏览器控制台是否发现了真正的问题。
gulp.task('minified', function () {
return gulp.src(paths.concatScripts)
.pipe(sourcemaps.init())
//.pipe(uglify())
.pipe(sourcemaps.write('.', { addComment: false }))
.pipe(gulp.dest(publishUrl));
