Question

我有一个angular-2应用程序。

我尝试运行ng serve，但收到此错误：

ERROR in ./src/main.ts
Module build failed: TypeError: Cannot read property 'newLine' of undefined
    at Object.getNewLineCharacter (/Users/eladb/WorkspaceQa/Gasolina/node_modules/typescript/lib/typescript.js:8062:20)
    at Object.createCompilerHost (/Users/eladb/WorkspaceQa/Gasolina/node_modules/typescript/lib/typescript.js:44978:26)
    at Object.ngcLoader (/Users/eladb/WorkspaceQa/Gasolina/node_modules/@ngtools/webpack/src/loader.js:170:31)
 @ multi webpack-dev-server/client?http://localhost:4200 ./src/main.ts

ERROR in ./src/polyfills.ts
Module build failed: TypeError: Cannot read property 'newLine' of undefined

    at Object.ngcLoader (/Users/eladb/WorkspaceQa/Gasolina/node_modules/@ngtools/webpack/src/loader.js:170:31)
 @ multi ./src/polyfills.ts
webpack: Failed to compile.

我尝试在本地和全局卸载并重新安装angular / cli。

但我仍然会收到此错误。

这是我的package.json

Answer 1

您使用的是哪个版本的CLI？这一切看起来都过时了

这可能有所帮助：

npm uninstall -g angular-cli
npm install -g @angular/cli

官方文档：https://cli.angular.io/

然后，生成新项目：ng new myapp

重新安装angular / cli之后：模块构建失败：TypeError：无法读取未定义的属性'newLine'
