Problems installing ESP32 toolchain

Golioth Device Help

Hello,

I have been following the directions for installing the ESP32 toolchain and hit a roadblock. I have been following the directions on the docs site, but the toolchain is not found. Am I doing something wrong?

Here is the error output from my terminal (linux)
`

Hi Maxim,

Looks like the West build system is having troubles finding the Espressif toolchain, could you run the following command in your terminal and let us know what you see?

echo $PATH

That will let us know where your terminal is searching for the toolpath.

Could you also please run the following?

export -r

As you can see in the lines you pasted above, we would expect to see the ESPRESSIF_TOOLCHAIN_PATH and the ZEPHYR_TOOLCHAIN_VARIANT set in your export variables. If these are different or if your $PATH is not what is listed after the Espressif toolchain install, that is likely the source of the problems.
