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"
