typescript - TypeScript 中的类型“字符串”上不存在属性“查找”

问题描述

我收到这个错误Property 'find' does not exist on type 'string'.

我运行脚本的方式和详细错误：

$ npm run build-next

> admin-ui@1.0.0 build-next /Users/.../admin-ui
> next build

我的tsconfig.json文件：

{
  "compilerOptions": {
    "allowJs": true,
    "allowSyntheticDefaultImports": true,
    "jsx": "preserve",
    "lib": [
      "dom",
      "esnext"
    ],

    "node_modules"
  ],
  "include": [
    "next-env.d.ts",
    "**/*.ts",
    "**/*.tsx"
  ]
}

package.json脚本部分：

"scripts": {
    "dev": "node server.js",
    "build-server": "tsc --esModuleInterop server.ts",
    "build-next": "next build",
    "start": "NODE_ENV=production node server.js"

解决方案

编译器：+Infinity，我：0

find确实不存在于字符串上！indexOf是我一直在寻找的。
