遇到问题第一个就是上网寻找帮助，发现有人说flutter doctor就解决了，但flutter doctor并没有显示有任何问题。
具体问题如下：
clang: error: linker command failed with exit code 1 (use -v to see invocation)
note: Using new build system
note: Building targets in parallel
note: Planning build
note: Constructing build description
warning: no rule to process file 'xxx' of type 'text' for architecture 'x86_64' (in target 'xxx' from project 'Pods')
Could not build the application for the simulator.
Error launching application on iPhone 11 Pro.
经过多次 关键字 变更搜索后，终于找着问题解决方法了
问题是：framework not found Flutter
解决：查看配置路径，找到flutter.framework，添加flutter库
出问题的文件路径
2、解压包
双击压缩包把Flutter.framework覆盖掉
这里可以对比一下前后变化，多了一个Flutter可执行文件
覆盖前的Flutte.framework
覆盖后的Flutte.framework
pp: 其实这个问题是，清理电脑内存的时候，把图中Flutter这个可执行文件删了😄
