Flutter环境问题:Requested 'Requested 'libusbmuxd >= 1.1.0' but version of libusbmuxd is 1.0.10

遇到这个这个问题有时候感觉很懵逼的，但是这个的含义就是环境已经升级了但是自己的还是老版本

Requested 'libusbmuxd >= 1.1.0' but version of libusbmuxd is 1.0.10

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables libusbmuxd_CFLAGS
and libusbmuxd_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
