{
  "compilerOptions": {
      "target": "ES2016",
      "module": "commonjs",
      "lib": ["esnext", "dom"],           
      "allowJs": true,                    
      "checkJs": false,                   
      "jsx": "react",                     
      "declaration": false,                  
      "declarationMap": false,               
      "sourceMap": false,                    
      "skipDefaultLibCheck": true,
      "skipLibCheck": true,
      "noEmit": true,                        
      "isolatedModules": true,               
      "strict": false, 
      "noImplicitAny": false,                 
      "strictNullChecks": false,              
      "strictFunctionTypes": false,           
      "strictBindCallApply": false,           
      "strictPropertyInitialization": false,  
      "noImplicitThis": false,                
      "alwaysStrict": false,                  
      "noUnusedLocals": false,                
      "noUnusedParameters": false,            
      "noImplicitReturns": false,             
      "noFallthroughCasesInSwitch": false,    
      "baseUrl": "./",                       
      "typeRoots": [
          "./types/",
          "./node_modules/@types"
      ], 
      "allowSyntheticDefaultImports": true,
      "esModuleInterop": true,
      "forceConsistentCasingInFileNames": true,
      "resolveJsonModule": true
  }
}

最后结束并重新运行即可解决。
