After updating git, you need to run tools/get.py to pull the latest tools. GIT head now required python3 to be installed (and it's part of the tools JSON) because Python2 is EOL on Jan 1 2020.

Great, am going to have a look at that, Many thanks 😃 Le lun. 16 sept. 2019 à 19:21, Earle F. Philhower, III < [email protected]> a écrit :

Closing. We also have Mac builds now as a part of CI, so the tools update should get you going. See https://travis-ci.org/esp8266/Arduino/jobs/584763541

derrgis · 2019-09-17T16:14:38Z

Sorry to come again. Before to go further here is what happens.
Today I've upgrade my Python3 version on my Mac OS.10.11.6 via homebrew wihtout problem.

After the command cd esp8266/tools and python3 get.py as described for the download binary tools https://arduino-esp8266.readthedocs.io/en/latest/installing.html#boards-manager

I don't have that python folder installed in tools and compilation still gives
fork/exec /Users/.../Documents/Arduino/hardware/esp8266com/esp8266/tools/python3/python3: no such file or directory Erreur de compilation pour la carte Generic ESP8266 Module
I also get this afer brew command and I can't understand if that comes from my particular computer setup or from the esp distribution.

it seems not easy, where the best to go now ?

earlephilhower · 2019-09-17T16:26:51Z

Ah, I ran into that, too, on the CI integration. Homebrew installs python, but doesn't actually install the needed certificates into the Mac keyring or whatever. I don't understand their reasoning, but w/o it the HTTPS functionality of Python3 is broken.

I followed the directions and added below, which actually installs the certs and makes things work:
cd "/Applications/Python 3.7/" && sudo "./Install Certificates.command"

You'll need to do the same, possibly changing the path to the one you installed Python3 into. I don't remember if I found that out from the homebrew install logs or StackOverflow, but it was quite a puzzler for me (last Mac I used had a PowerPC chip in it!).

derrgis · 2019-09-17T16:56:10Z

Wow great ! it helps go further. Indeed there was a certificate issue.
The command works as expected.

Unfortunately I get a permission denied on dist/python3-macosx-placeholder.tar.gz
and I unable to find where is that file. Do you have an idea?
Nothing in esp8266/tools/dist. Just empty ...

earlephilhower · 2019-09-17T17:00:23Z

That's a FS permission issue on your computer. Not sure what Mac permissions look like, or where you've installed the git repo (could it be in a protected spot, or installed using sudo git clone...?), but assuming it's in the right spot a judicious use of sudo python3 get.py should allow it to write to that directory no matter what.

derrgis · 2019-09-17T17:08:30Z

Pfiouuu you saved my day.
Please come see me if you come in Saint-Etienne, France, I owe you a beer :)))

if @earlephilhower were to call in all the beers he's owed, he'd drown 😂

Leaving this here for others to find.
This was a perplexing issue, I've used Arduino 1.8.9 successfully for many months and just decided to upgrade, which broke uploading to my nodemcu with the above python error. I looked here for an answer, found this supremely complex and confusing response and decided to look further.
I just simply installed the latest stable release of python 3 from python.org (only 30MB) and it's working just fine again. The installer even notified the user at the end of the install regarding the cert stuff, which is specific to Mac users. Python 3 installer came with a packaged autoscript to clean that up too. Much, much easier route to take...just my .02.

Thanks so much for putting this SOLUTION HERE! The other way was just too complicated. Your solution was something I could. Just do not miss the addition step that is called out on the last screen. You MUST go to the Finder folder and run the certificate script to make everything work. Thanks again it was MAGIC !!!!!!!!

Hello, I have a similar problem derrgis but I managed to succesfully install the certifications in the directory where python 3.8 is (I have python 3.8). I have since written in the terminal cd esp8266/tools and python3 get.py and gotten this to work succesfully as well. However I still get an error message trying to compile in the Arduino IDE. I now get the error message :

env: python3: No such file or directory exit status 127 Error compiling for board Generic ESP8266 Module.

The problem is that the symlink for python3 is incorrect. To correct it:

$ cd /Users/[your-username]/Library/Arduino15/packages/esp8266/tools/python3/3.7.2-post1/
$ rm python3
$ which python3
$ ln -s [path-returned-by-the-above-command] python3

I do not have Python 3 installed but 2. So what? Should I install Python 3 and do the steps? Thanks

aleonnet · 2020-05-11T20:19:37Z

Python 2 is gone... I suggest you to install Python 3.

In a desperate way to avoid the problem mentioned in the post, i remove Python (previously installed in default route), RE installed in C:\Users{USERNAME}\Documents\Arduino\hardware\esp8266com\esp8266\tools (where repo resides) and run a GIT BASH from here, wrote "python3 get.py" and no results...deleting the number 3 DID THE JOB! Try this line "python get.py" and maybe youll get the binary tools in a lucky strike like me hehehe. Never give up guys! Regards.
