本地环境IDF v5.2.0一直在使用正常（VSCODE/WIN64）今天刚从https://gitee.com/EspressifSystems/esp-at下载的包，python build.py menuconfig和python build.py build一直报错，如下（kconfiglib从14.1.0降级到13.7.1、12.1.0均没用）：
File "D:\esp-at\esp-idf\tools\kconfig_new\confgen.py", line 163, in _opt_defined
if opt.orig_type in (kconfiglib.BOOL, kconfiglib.TRISTATE) and opt.str_value != 'n':
^^^^^^^^^^^^^^^

I ran into this same problem today. It occurred after I updated pip to the latest version based on a message I saw though perhaps that was just coincidental and I caused this problem in some other way. I do switch back and forth between ESP-IDF versions which normally is not a problem, but at any rate to recover from this error which occurred with my ESP-IDF v4.4.2 I had to do the following:
1) delete the ~/.espressif/python_env/idf4.4_py3.9env folder or whatever IDF version python environment is having the problem
2) do the git clone of 4.4.2 again though if you don't want to overwrite your esp-idf folder for this you can clone to a different folder and then discard it. The purpose of this git clone for fixing this problem isn't to get the esp-idf folder contents, but to update the .espressif folder's python environment.
3) do the normal "./update.sh all" in your esp-idf folder
4) do the normal export.sh

Basically, the message is coming from a change to the python environment where kconfiglib no longer supports BOOL. Since I am switching between a v4 and a v5 ESP-IDF where the later made significant changes to how it uses kconfig, I must have inadvertently broken something, but the above re-installation fixed it. Good luck and I hope this works for you.
