javascript - 包括 Jotted 的 Codemirror 插件和 Angular gulp

Question

我正在尝试将 Jotted javascript 库与 gulp-Angular 项目结合使用。该库本身工作正常，但我试图包含该库的 Codemirror 插件，但遇到了问题。当我尝试添加库并运行 gulpserve 时，出现以下错误:

解析错误:“js/codemirror.js”，第 4 行:意外的保留字

导致问题的行如下所示:

从'../util.js'导入*作为util

我见过一些人引用使用 babel 来解决此类问题，但解决方案似乎有点超出了我的技能水平。

这是该插件的链接:

我当前的server.js

'use strict';

var path = require('path');
var gulp = require('gulp');
var conf = require('./conf');
var babel = require('gulp-babel');

var browserSync = require('browser-sync');
var browserSyncSpa = require('browser-sync-spa');

var util = require('util');

var proxyMiddleware = require('http-proxy-middleware');

function browserSyncInit(baseDir, browser) {
    browser = browser === undefined ? 'default' : browser;

    var routes = null;
    if (baseDir === conf.paths.src || (util.isArray(baseDir) && baseDir.indexOf(conf.paths.src) !== -1)) {
        routes = {
            '/bower_components': 'bower_components'
        };
    }

    var server = {
        baseDir: baseDir,
        routes : routes
    };

    /*
     * You can add a proxy to your backend by uncommenting the line below.
     * You just have to configure a context which will we redirected and the target url.
     * Example: $http.get('/users') requests will be automatically proxified.
     *

     */
    // server.middleware = proxyMiddleware('/users', {target: 'http://jsonplaceholder.typicode.com', changeOrigin: true});

    browserSync.instance = browserSync.init({
        startPath: '/',
        server   : server,
        browser: browser,
        host: '192.168.0.20',
        https: false,
        port   : parseInt(process.env.GULP_PORT) || 8684
    });
}

browserSync.use(browserSyncSpa({
    selector: '[ng-app]'// Only needed for angular apps
}));

gulp.task('serve', ['watch'], function () {
    browserSyncInit([path.join(conf.paths.tmp, '/serve'), conf.paths.src]);
});

gulp.task('serve:dist', ['build'], function () {
    browserSyncInit(conf.paths.dist);
});

gulp.task('serve:e2e', ['inject'], function () {
    browserSyncInit([conf.paths.tmp + '/serve', conf.paths.src], []);
});

gulp.task('serve:e2e-dist', ['build'], function () {
    browserSyncInit(conf.paths.dist, []);
});

var gulp = require('gulp');
var webserver = require('gulp-webserver');

gulp.task('webserver', function() {
  gulp.src('src')
    .pipe(webserver({
      host: '0.0.0.0',
      livereload: true,
      directoryListing: true,
      open: true
    }));
});

我当前的 gulpfile.babel.js

/**
 *  Welcome to your gulpfile!
 *  The gulp tasks are splitted in several files in the gulp directory
 *  because putting all here was really too long
 */

'use strict';

var gulp = require('gulp');
var wrench = require('wrench');
var babel = require('gulp-babel');

/**
 *  This will load all js or coffee files in the gulp directory
 *  in order to load all gulp tasks
 */
wrench.readdirSyncRecursive('./gulp').filter(function (file) {
    return (/\.(js|coffee)$/i).test(file);
}).map(function (file) {
    require('./gulp/' + file);
});


/**
 *  Default task clean temporaries directories and launch the
 *  main optimization build task
 */
gulp.task('default', ['clean'], function () {
    gulp.start('build');
});

我的猜测是，您在不支持模块的 ES5 环境中使用 import 语句运行代码。

如果您像我怀疑的那样在 Node 中运行它，则可以使用 required 代替。
