解决“微信开发者工具导入wepy-cli生成的项目后控制台报错显示app.json: app.json 未找到”的问题

微信小程序开发者工具版本：

导入之前项目根目录下的project.config.json文件：

{ 
  "description": "A WePY project",
  "setting": { 
    "urlCheck": true,
    "es6": false,
    "postcss": false,
    "minified": false
  },
  "compileType": "miniprogram",
  "appid": " wx4e367dd65dd063b6",
  "projectname": "heima_ugou",
  "miniprogramRoot": "./dist"
}

导入之后项目根目录下的project.config.json文件被修改为：

{ 
  "description": "项目配置文件",
  "packOptions": { 
    "ignore": []
  },
  "setting": { 
    "urlCheck": true,
    "es6": true,
    "enhance": false,
    "postcss": true,
    "preloadBackgroundData": false,
    "minified": true,
    "newFeature": false,
    "coverView": true,
    "nodeModules": false,
    "autoAudits": false,
    "showShadowRootInWxmlPanel": true,
    "scopeDataCheck": false,
    "uglifyFileName": false,
    "checkInvalidKey": true,
    "checkSiteMap": true,
    "uploadWithSourceMap": true,
    "compileHotReLoad": false,
    "useMultiFrameRuntime": false,
    "useApiHook": true,
    "babelSetting": { 
      "ignore": [],
      "disablePlugins": [],
      "outputPath": ""
    },
    "useIsolateContext": true,
    "useCompilerModule": true,
    "userConfirmedUseCompilerModuleSwitch": false,
    "packNpmManually": false,
    "packNpmRelationList": []
  },
  "compileType": "miniprogram",
  "libVersion": "2.13.1",
  "appid": "wx4e367dd65dd063b6",
  "projectname": "heima_ugou",
  "miniprogramRoot": "./dist",
  "debugOptions": { 
    "hidedInDevtools": []
  },
  "scripts": { },
  "isGameTourist": false,
  "simulatorType": "wechat",
  "simulatorPluginLibVersion": { },
  "condition": { 
    "search": { 
      "current": -1,
      "list": []
    },
    "conversation": { 
      "current": -1,
      "list": []
    },
    "game": { 
      "current": -1,
      "list": []
    },
    "plugin": { 
      "current": -1,
      "list": []
    },
    "gamePlugin": { 
      "current": -1,
      "list": []
    },
    "miniprogram": { 
      "current": -1,
      "list": []
    }
  }
}

问题原因：

导入项目后project.config.json文件被微信开发者工具修改，缺少代码："miniprogramRoot": "./dist"从而导致微信开发者工具无法找到app.json文件进而报错：app.json: app.json 未找到

解决办法：

向project.config.json文件中添加如下代码后从新编译即可：

"miniprogramRoot": "./dist"
