Can you give a little more info on the steps you've taken before this and where you're at. I'm assuming you just ran the install.sh script, but what other steps have you followed so far?

[Paladin]

I've been simply following the getting started guide. Its been about 8 months since i used the ESP32 toolchain, so I decided to remove my old esp-idf folder and go through the setup process from step 1. When I ran

Code: Select all

./install.sh

I got the above error. I don't know what to try on my own. Google did not turn up anything I found useful.

I've had to do this a few times on different macs and linux distros so I've seen a lot of errors but don't remember this one. Can you send me the link to the exact getting started guide? v4 just came out which is under latest but it's easy to accidentally read an older one or follow the make guide when you wanna do cmake (idf.py). That's why I'm asking.

[Paladin]

Thank you for taking the time to help.

here's the guide I'm using:

No problem, I very well how rough it can be to navigate Espressif software lol. Did you make sure to follow all the steps in https://docs.espressif.com/projects/esp ... setup.html as well?

[Paladin]

yes I did.

I just noticed that your pip is super old (I think).

https://pypi.org/project/pip/ says that current version is 19.3.1

Try upgrading it

Code: Select all

pip install -U pip

Then rerun the install. no-warn-script-location is a valid flag so maybe your version of pip is too old to have it?

Edit: If you run into trouble upgrading your pip, look at this https://stackoverflow.com/a/47299380

So, ironically, the very first step in the getting started guide is to install pip:

Code: Select all

sudo easy_install pip

which I did, despite having pip already installed...and the version number ticked up, so I didn't even think to check that I had the latest version.

anyways, updating pip seems to have gotten my toolchain up and running. Now I need to dig back into my old project to see if I can get it up and running again.

Thank you for the help.

Glad you got it working.
