当尝试使用以下命令以角度4创建生产版本时:
ng build --prod
和
ng build --prod --aot=false
我在控制台中遇到以下错误:
chunk {scripts} scripts.d0765ae1a4bba4717f75.bundle.js (scripts) 381 kB [initial] [rendered]
chunk {0} main.20075152b680cf048d04.bundle.js (main) 1.79 MB [initial] [rendered]
chunk {1} polyfills.24783bc638c31078c9bb.bundle.js (polyfills) 60 kB [initial] [rendered]
chunk {2} styles.510fc4debb3c7f60a7cb.bundle.css (styles) 240 kB [initial] [rendered]
chunk {3} vendor.03d0b614f00528c8edb5.bundle.js (vendor) 9.27 MB [initial] [rendered]
chunk {4} inline.31e1fb380eb7cf3d75b1.bundle.js (inline) 798 bytes [entry] [rendered]
ERROR in vendor.03d0b614f00528c8edb5.bundle.js from UglifyJs
undefined
也不会创建dist文件夹。搜索后,我遇到了一个修复程序,将tsconfig.json中的目标从“ es5”更改为“ es6”。进行此更改后,将在控制台中创建没有错误的内部版本。但是当我运行index.html时,在浏览器控制台中出现以下错误:
Uncaught TypeError: Cannot convert undefined or null to object
at Function.getPrototypeOf (<anonymous>)
vendor.62bee233ca73b4fe95c7.bundle.js:1
我尝试了不同的解决方案,但无法解决此错误,项目package.json
