angular - [at-loader] node_modules\@types\jasmine 中的错误

Question

我的 webpack 构建开始突然失败，没有任何包被更新。我假设一些次要版本更新导致了这个，但无法弄清楚如何解决它。有谁知道该怎么做吗？

ERROR in [at-loader] node_modules\@types\jasmine\index.d.ts:39:52 
    TS1005: '=' expected.
ERROR in [at-loader] node_modules\@types\jasmine\index.d.ts:39:38 
    TS2371: A parameter initializer is only allowed in a function or constructor implementation.
ERROR in [at-loader] node_modules\@types\jasmine\index.d.ts:39:46 
    TS2304: Cannot find name 'keyof'.

看起来你的 @types/jasmine 库已升级到最新版本，因为你有插入符号:

"@types/jasmine": "^2.2.34",

最新版本存在此 bug 所建议的问题。所以现在尝试在 package.json 中将版本设置为 2.5.41 :

"devDependencies": {
  "@types/jasmine": "2.5.41"
}

也许您必须删除 node-modules 文件夹并运行 npm install 以进行全新安装。
