fail to install esp-idf env

[wsghr2021]

hi guys,

I installed esp-idf development env. But the esp32-elf can't be identified.

F:\03_code\esp-idf>install.bat

Then export:

F:\03_code\esp-idf>export.bat
Setting IDF_PATH: F:\03_code\esp-idf

Adding ESP-IDF tools to PATH...

I have uninstalled and installed esp-idf env several times, but it still not working.
Any ideas?
thx a lot.
