我继承了一个非常不寻常的网站，它是C#和NodeJS的混合体(使用TypeScript(。我们在Azure DevOps上建立了一个持续集成环境，用于构建网站并将其部署到测试环境中。自三月份以来，我们就没有构建过这个网站，现在构建过程突然中断了。我们不得不将package.json中对"gump"的引用从"github:gulpjs/gulp#4.0"(已不存在(更改为"github:culpjs/gulp#71c094a51c7972d26f557899ddecab0210ef3776"，但现在调用gump的构建过程步骤("node-node_modules\gulp\bin\gulp.js package"(失败，并出现以下错误(这来自DevOps构建日志(：

此链接-https://github.com/babel/gulp-babel/issues/154-似乎暗示了browserfy的问题(或者至少是browserfy和babel core之间的不兼容(？唯一的建议是停止使用browserfy。对我来说，神秘的是，为什么这在以前有效，但现在失败了，因为我们所改变的只是提到了吞咽。
有人能向我解释一下是什么导致了这个错误以及如何解决吗？任何帮助都将不胜感激。
引发错误的吞咽任务是：
gulp.task("bundle", function () {
return browserify({
basedir: '.',
debug: true,
entries: [config.appMain],
cache: {},
packageCache: {}
})
.plugin(tsify)
.bundle()
.pipe(source('app.bundle.js'))
.pipe(buffer())
.pipe(sourcemaps.init())
.pipe(babel({ presets: ['env'] }))
.pipe(uglify())
.pipe(sourcemaps.write('./', { includeContent: false, sourceRoot: '../' }))
.pipe(gulp.dest(config.jsDest));
});
config.appMain="应用/main.ts"config.jsTest="./wwwroot/js">
gullfile.js顶部的相关"要求"是：
var gulp = require('gulp');
var browserify = require("browserify");
var tsify = require("tsify");
var source = require('vinyl-source-stream');
var buffer = require('vinyl-buffer');
var sourcemaps = require('gulp-sourcemaps');
var babel = require('gulp-babel');
var uglify = require("gulp-uglify");
var config = require('./gulp.config')();
软件包.json的devDependencies版本为：
"@types/core-js": "^0.9.34",
"@types/node": "^6.0.45",
"babel-preset-env": "^1.7.0",
"browserify": "^16.2.3",

我已经尝试过使用babelify，所以吞咽任务变成了：
gulp.task("bundle", function () {
return browserify({
basedir: '.',
debug: true,
entries: [config.appMain],
cache: {},
packageCache: {}
})
.transform(babelify, { presets: ['env'] })
.plugin(tsify)
.bundle()
.pipe(source('app.bundle.js'))
.pipe(buffer())
.pipe(sourcemaps.init())
.pipe(uglify())
.pipe(sourcemaps.write('./', { includeContent: false, sourceRoot: '../' }))
.pipe(gulp.dest(config.jsDest));
});
但当我在本地执行"nodenode_modules\gulp\bin\gulp.js包"时，我会得到完全相同的错误。
如果您需要更多详细信息或代码，请告诉我。谢谢你能提供的任何帮助。
我的一位同事解决了这个问题。当然，解决方案是使用babelify。然而，我的实现是错误的。在gullow任务中的用法是：
gulp.task("bundle", function () {
return browserify({
transform: [["babelify", { "presets": ["@babel/preset-env"] }]],
basedir: '.',
debug: true,
entries: [config.appMain],
cache: {},
packageCache: {}
})
.plugin(tsify)
.bundle()
.pipe(source('app.bundle.js'))
.pipe(buffer())
.pipe(sourcemaps.init())
.pipe(babel({ presets: ["@babel/preset-env"] }))
.pipe(uglify())
.pipe(sourcemaps.write('./', { includeContent: false, sourceRoot: '../' }))
.pipe(gulp.dest(config.jsDest));
});
package.json devDependencies中使用的包和版本为：
"browserify": "^16.2.3",
"@babel/core": "^7.2.0",
"@babel/preset-env": "^7.2.0",
"babelify": "^10.0.0",
"gulp-babel": "8.0.0",
