Question

更新npm模块后，我尝试运行ng build -prod之前工作正常，我一直收到以下错误：

TypeError: extractedChunk.getNumberOfModules is not a function at ExtractTextPlugin.<anonymous> (/Users/myUserName/dev-test/demo/node_modules/extract-text-webpack-plugin/dist/index.js:246:32) at Array.forEach (native) at Compilation.<anonymous> (/Users/myUserName/dev-test/demo/node_modules/extract-text-webpack-plugin/dist/index.js:245:27) at Compilation.applyPluginsAsyncSeries (/Users/myUserName/dev-test/demo/node_modules/@angular/cli/node_modules/tapable/lib/Tapable.js:206:13) at sealPart2 (/Users/myUserName/dev-test/demo/node_modules/@angular/cli/node_modules/webpack/lib/Compilation.js:653:9) at next (/Users/myUserName/dev-test/demo/node_modules/@angular/cli/node_modules/tapable/lib/Tapable.js:202:11) at Compilation.compilation.plugin (/Users/myUserName/dev-test/demo/node_modules/@angular/cli/node_modules/webpack/lib/ProgressPlugin.js:111:6) at next (/Users/myUserName/dev-test/demo/node_modules/@angular/cli/node_modules/tapable/lib/Tapable.js:204:14) at /Users/myUserName/dev-test/demo/node_modules/extract-text-webpack-plugin/dist/index.js:241:13 at /Users/myUserName/dev-test/demo/node_modules/async/dist/async.js:421:16 at iteratorCallback (/Users/myUserName/dev-test/demo/node_modules/async/dist/async.js:998:13) at /Users/myUserName/dev-test/demo/node_modules/async/dist/async.js:906:16 at /Users/myUserName/dev-test/demo/node_modules/extract-text-webpack-plugin/dist/index.js:224:15 at /Users/myUserName/dev-test/demo/node_modules/async/dist/async.js:421:16 at iteratorCallback (/Users/myUserName/dev-test/demo/node_modules/async/dist/async.js:998:13) at /Users/myUserName/dev-test/demo/node_modules/async/dist/async.js:906:16 at /Users/myUserName/dev-test/demo/node_modules/extract-text-webpack-plugin/dist/index.js:213:21 at rebuilding.forEach.cb (/Users/myUserName/dev-test/demo/node_modules/@angular/cli/node_modules/webpack/lib/Compilation.js:521:29) at Array.forEach (native) at callback (/Users/myUserName/dev-test/demo/node_modules/@angular/cli/node_modules/webpack/lib/Compilation.js:521:15) at processModuleDependencies (/Users/myUserName/dev-test/demo/node_modules/@angular/cli/node_modules/webpack/lib/Compilation.js:540:5) at _combinedTickCallback (internal/process/next_tick.js:95:7)

npm版本：5.4.2

我被卡住了，因为我无法通过简单的更新找出真正出错的地方。

有什么想法吗？

这为我修好了。（基本上如果你在安装过程中查看npm日志，它说extract-text-webpack-plugin需要webpack 3.1.0依赖。

所以只需更新你的webpack，例如：

npm install webpack@3.1.0 --save-dev

＆n;更新后的TypeError＆＃39;和＆＃39; ng build -prod＆＃39;
