在开发flutter的macOS版时，报这个错误：./macos/Pods/Pods.xcodeproj: warning: The macOS deployment target 'MACOSX_DEPLOYMENT_TARGET' is set to 10.6, but the range of supported deployment target versions is 10.9 to 12.3.99.
可以很明确的看到文件是：/macos/Pods/Pods.xcodeproj，虽然这个warning并不影响程序的运行，看确实看了不舒服，于是打开/macos/Pods/Pods.xcodeproj，搜索：MACOSX_DEPLOYMENT_TARGET，一共有3处，将他对应的值10.6，修改为10.9，问题解决。
