我的Vue/TypeScript项目中有一个全局类型。在.ts文件中，一切都很好，Eslint可以看到，但在.vue文件中，Eslind抛出未定义类型的错误。TypeScript没有抛出任何错误，并且看到了此类型。下面的配置和代码示例。

typescript esint的故障排除文档中有一个条目：
无undef lint规则不使用TypeScript来确定存在的全局变量，而是依赖于ESLint的配置。
我们强烈建议您不要在TypeScript项目上使用无undef lint规则。它提供的检查已经由TypeScript提供，而无需配置——TypeScript只是做得更好。
他们建议通过在ESLint配置中添加覆盖来禁用TypeScript的no-undef，如下所示：
overrides: [
{
files: ['*.ts', '*.vue'],
rules: {
'no-undef': 'off',
},
},
],
请注意，这将禁用所有*.vue文件的no-undef，无论它们使用TypeScript还是JavaScript。
