我刚刚安装了 iOS 14 beta 并将 Xcode 更新到最新的 Version 12 beta 3。

*Unable to locate DeviceSupport directory with suffix 'DeveloperDiskImage.dmg'. This probably means you don't have Xcode installed, you will need to launch the app manually and logging output will not be shown! Could not run build/ios/iphoneos/Runner.app on 00008020-001338A20E01002E. Try launching Xcode and selecting "Product > Run" to fix the problem: open ios/Runner.xcworkspace*当我从flutter运行应用程序时出现错误 。

我可以从 Xcode 运行该应用程序，但是一旦 USB 电缆断开，该应用程序将无法打开/应用程序崩溃。

请帮助我找出问题所在并解决

我无法为 iOS 构建 flutter 项目，出现如下错误

Xcode's output:\n\xe2\x86\xb3\n    In file included from /Users/sulfy/Developer/flutter/.pub-cache/hosted/pub.dartlang.org/path_provider-2.0.5/ios/Classes/FLTPathProviderPlugin.m:5:\n    /Users/sulfy/Developer/flutter/.pub-cache/hosted/pub.dartlang.org/path_provider-2.0.5/ios/Classes/FLTPathProviderPlugin.h:5:9: fatal error: 'Flutter/Flutter.h' file not found\n    #import <Flutter/Flutter.h>\n            ^~~~~~~~~~~~~~~~~~~\n    1 error generated.\n    note: Using new build system\n    note: Planning\n    note: Build preparation complete\n    note: Building targets in parallel\n

尝试过

\n
1. 吊舱解体
\n
2. rm ios/Flutter/Flutter.podspec
\n
3. 扑干净
\n
4. 扑扑酒吧得到
\n
5. 吊舱安装
\n
6. 清理导出数据
\n
7. 扑腾跑
\n

还是一样，我无法摆脱这个错误。\n我什至尝试从 pubsec.yaml 中删除路径提供程序插件

任何帮助将不胜感激，因为我已经在这个问题上坚持了 24 小时以上

我有一张包含基本员工详细信息的表格，如下所示：

表：tblEmployees

EmpID   Name    Contact   Sex
100     John    55555     M
200     Kate    44444     F
300     Sam     88888     M

我想获得如下特定员工的查询结果，其中 EmpID = 200

Col1    Col2
EmpID   200
Name    Kate
Sex     F
