Can the user that you run idf.py as write to that directory? If not, did you create it as root or something? Can you do a 'ls -l' in the esp directory?

I faced the same issue
I tried "su" to proceed the command line as root user, but still it appear "permission denied"

finally I can launch the scripts using this way

sudo python3 <path_to_the_folder>/vendors/espressif/esp-idf/tools/idf.py build

for example: in my case, it run with this below command line.
sudo python3 /Users/Admin/Documents/EMBEDDED/workspace_AWS/FreeRTOS/vendors/espressif/esp-idf/tools/idf.py -DVENDOR=espressif -DBOARD=esp32_wrover_kit -DCOMPILER=xtensa-esp32 build

I just now had the same error show up when going thru the 'getting started guide' at the end of the . ./export.sh script. I went into the tools directory and saw all the *.py files did not have the executable bits set. I did a 'chmod +x idf.py and the export.sh worked. I'm just now wondering if I should set those other py files as executable. Just wondering. I will continue with the installation process.

The only .py file which should be executable is install.py.
export.py is not executable, because you do not use it straight, you should It is also described in the docs.
