错误错误:未使用‘@ts-TS2578-TS2578’指令
错误错误:未使用‘@ts-TS2578-TS2578’指令
提问于 2021-01-11 23:25:20
上周，我使用ts-migrate将我们的代码库迁移到TypeScript。该工具在TS文件中添加了大量的// @ts-expect-error注释，以使其通过TS编译器和类型检查。然而，当我运行yarn run tsc来检查我的代码库时，我得到了5k+错误，声明error TS2578: Unused '@ts-expect-error' directive.，我是否遗漏了一段配置，声明这些类型的错误是正常的？寻找任何建议，让这通过TS编译器。
这是我的TS配置以供参考。

我也有同样的问题，但我的错误也出现在那些非测试文件中。我认为这是因为ts-migrate和你的集成开发环境的打字版本不匹配。我在package.json中添加了一个typescript包，以使两个版本相同，从而修复了它

答案很简单。您在没有错误的地方使用了// @ts-expect-error。我建议在VS代码中通过正则表达式\s*\/\/\s*@ts-expect-error (to nothing)替换它，以删除所有注释。
