==编译失败==

解决方法：

1、找到缺失文件的目录

D:\windowsoftInstalled\mixly\mixly2.0-win32-x64\arduino-cli\Arduino15\packages\esp32\tools\xtensa-esp32-elf-gcc\esp-2021r2-patch5-8.4.0\xtensa-esp32-elf\include\c++\8.4.0\bits

发现给目录下的确缺少了必要的头文件

2、进入

D:\windowsoftInstalled\mixly\mixly2.0-win32-x64\arduino-cli\Arduino15\packages\esp32\tools\xtensa-esp32-elf-gcc\esp-2021r2-patch5-8.4.0\xtensa-esp32-elf\include\c++\8.4.0\xtensa-esp32-elf\bits

将这个目录的所有文件全部复制粘贴到第1步的目录中。

3、重新编译正常
