"ng serve -prod“犯了一些错误

Question

内部错误:未知标识符300

未找到./src/main.ts模块中的错误:错误:无法解决。/$$_gendir/app/app.module.ngFactory‘in’C：\Users.\ng-webapp \src‘@/src/main.ts 3:0-74 @ multi dev-server/client？http://localhost:4200 ./src/main.ts

谢谢你的帮助!

我从google找到了一些答案，但它对我不起作用，比如更新的“角/cli”版本，或者安装了增强的-解析@3.3.0，但是仍然是相同的错误。

这是package.json中的一些内容：

Answer 1

您可以通过以下命令构建您的命令：

ng build --prod --aot=false -bh /<base-href> -d /<dir>

用您自己的基本href替换<base-href>，用项目文件夹名替换<dir>

Answer 2

正如我的comment中提到的，在新的角/cli版本中，如果您没有声明应用程序目录结构中存在的任何组件，它将引发这种类型的错误：

ERROR in Internal error: unknown identifier 300

ERROR in ./src/main.ts Module not found: Error: Can't resolve './$$_gendir/app/app.module.ngfactory' in 'C:\Users...\ng-webapp \src' @ ./src/main.ts 3:0-74 @ multi webpack-dev-server/client?http://localhost:4200 ./src/main.ts
