Uncaught Error: Cannot find module in Browserify Gulp when transpiled

Question

我一直在拼命地尝试解决由于我的 JS 中与 Browserify 捆绑在一起的依赖项而导致的极其缓慢的构建。为此，我提出了一些我的 gulp 文件调用的实用方法，如下所示...

const paths = require("./paths.gulpfile")
const gulp = require("gulp")
const uglify = require("gulp-uglify")
const sourcemaps = require("gulp-sourcemaps")
const browserify = require("browserify")
const shim = require("browserify-shim")
const watchify = require("watchify")
const babelify = require("babelify")
const source = require("vinyl-source-stream")
const buffer = require("vinyl-buffer")
const gutil = require("gulp-util")
const babel = require("gulp-babel")

const externalLibs = [
    "jquery", 
    "react",
    "react-dom",    
    "prop-types",
    "bootstrap-sass" 
]
const ignoredLibs = []
const vendorLibs = [
    "google-maps",
    "history", "history/createBrowserHistory",
    "lodash", "lodash/debounce",
    "path-to-regexp"
]

/**
 * JS related gulp tasks
 * 
 * @returns {object} utility functions for JS based gulp tasks.
 */
module.exports = function(compiledName) {

    /**
     * Bundle definition for dev.
     * 
     * @param {object} bundler 
     * @returns A bundle.
     */
    const appBundle = function(bundler) {
        return bundler.bundle()
            .pipe(source(compiledName + ".js"))
            .pipe(buffer())
            .pipe(sourcemaps.init({ loadMaps: true }))
            .pipe(babel())
            .pipe(sourcemaps.write("./"))
            .pipe(gulp.dest(paths.scriptsBuildPath))
    }

    /**

    const appMinBundle = function(bundler) {
        return bundler.bundle()
            .pipe(source(compiledName + ".min.js"))
            .pipe(buffer())

                mangle: {
                    except: [
                        "$",
                        "createBrowserHistory", 
                        "debounce",
                        "GoogleMapsLoader", 
                        "history",

                compress: true,
                mangle: true
            }))
            .pipe(sourcemaps.write("./"))
            .pipe(gulp.dest(paths.scriptsBuildPath))
    }

    /**

    const buildJs = function(debugMode, watch, bundleCallback) {
        const entryPoint = paths.scriptsSrcPath + "app.js"

        let bundler = browserify({
            entries: [entryPoint],
            transform: [[babelify, { "presets": ["react", "es2015", "stage-0"] }], shim],

        const bundler = browserify({

        //bundler.external(externalLibs)

        vendorLibs.forEach(function(lib) {
            bundler.require(lib)

        const bigBundle = vendorsBundle(bundler, env)
        return env == "production" ? vendorsMinBundle(bundler, env) : bigBundle

        buildVendorJs: buildVendorJs,
        appBundle: appBundle,
        appMinBundle: appMinBundle
    }
}

externalLibs 应该是 CDN 加载的并且被完全排除，vendorLibs 将被一起放入一个缩小的文件中，appBundle 是不言自明的。

在引入一个单独的 vendor.js 文件之前，我已经完成了这项工作，并且我在那里拥有所有依赖项，但我一直在让 React 在缩小时玩球时遇到问题，最终放弃并返回到CDN（甚至不准备再去那里——浪费了太多的日子）。

这让我剩下的供应商，但我现在遇到一个问题，即找不到 PropTypes....

_prelude.js:1 未捕获错误：找不到模块 'prop-types' 在 s (_prelude.js:1)

当 prop-types 是 vendor.js 包的一部分时，尝试访问 React 时出现了类似的错误 - 我不知道接下来要尝试什么。

我发现解决方案是我没有将新的外部组件添加到 package.json 中的 bowserify shim 配置...

  "browserify-shim": {
    "./node_modules/jquery/dist/jquery.js": "$",
    "react": "global:React",
    "react-dom": "global:ReactDOM",
    "prop-types": "global:PropTypes"
