react项目修改tsconfig.json设置了paths别名报错

Question

错误为：TypeError: Cannot add property paths, object is not extensible

// tsconfig.json
{
  "extends": "./paths.json",
  "compilerOptions": {
    "target": "es5",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "noFallthroughCasesInSwitch": true,
    "module": "esnext",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "react"
  },
  "include": ["src", "config-overrides.js"]
}

// paths.json
{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@/*": ["src/*"]
    }
  }
}

// config-overrides.js
const {
  override,
  addWebpackAlias,
} = require("customize-cra");
const path = require('path');

module.exports = override(
  // 扩展@指令符号
  addWebpackAlias({
    "@": path.resolve(__dirname, "src/"),
  }),
);

试试：

"compilerOptions": {
  +  "noFallthroughCasesInSwitch": true
}
