【问题描述】：

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

我已尝试在本地和全局范围内卸载并重新安装 angular/cli。

但我仍然收到此错误。

这是我的package.json

【问题讨论】：

标签： javascript angularjs typescript npm angular-cli

【解决方案1】：

您使用的是哪个版本的 CLI？这一切看起来都过时了

这可能会有所帮助：

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

【讨论】：

我按照你的建议做了，我尝试运行 ng serve 并得到了同样的错误。注册我的版本：➜ Your global Angular CLI version (1.4.9) is greater than your local version (1.2.0). The local Angular CLI version is used.
现在我得到这个错误：has no exported member 'node_modules/ng2-bootstrap/dropdown/index"' has no exported member 'DropdownModule'.
这可能是您导入 ng2-bootstrap 的问题，顺便说一下，它已重命名为 ngx-bootstrap。你应该查看官方文档：valor-software.com/ngx-bootstrap
