PermissionError: [Errno 13] Permission denied: '/home/cfk/esp/hello_world/build'

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"

[teddysaigon]

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.

[chegewara]

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

Code: Select all

source ./export.sh
or
. ./export.sh

It is also described in the docs.
