ESP32 Forum

Hey All,
I am super stoked to have my hands on a few ESP32s. From the command line I am able to build and flash the myapp code. In Eclipse I am unable to configure it properly to see my pyserial installation. Once everything is done compiling I get a "No module named serial" error. Can you please let me know how to point Eclipse in the right direction to see my python setup?

Thanks
Joe

Howdy Joe,
Did you by any chance see the documentation here:

http://esp-idf.readthedocs.io/en/latest ... setup.html

Step 0 is to install some pre-reqs an that looks like includes "python-serial"

Kolban,
Thanks for your response. I am able to build everything from the command line. When I run "pip3 list" it both shows pyserial is installed. My issue is the one step to get eclipse to be able to import (or see) the pyserial installation.

Howdy Joe, did you see this video tutorial:

Does your configuration dramatically change from that described there? If yes, can you describe your recipes?

Hi phando,

As hinted by WiFive, esptool.py currently only supports Python 2 (porting to Python 3 is in progress but still a reasonable time away.) A menuconfig option can be used to set a different Python interpreter, if the default "python" is Python 3 (can check via "python -v").

What OS are you using?

Angus

Thanks for all the responses.

@Angus, I am using OSX, I probably should have mentioned that in my first post.
@WiFive, yes, I have watched that video about ten times. My recipe looks exactly the same as the in the video.
@Kolban, great video and I just bought your book.

I didn't know esptool only works with python 2.7. I had two versions of python on my machine, so I made sure to remove 3.x. To be thorough, I reinstalled 2.7 with brew. From there I used brew to install pyserial. Now when I "pip list" it shows:
Still my problem exists. I can build and flash fine from the command line, but when I run the flash target from eclipse, it looks like it compiles fine and bails out right when it tries to flash the chip.
I have seen some threads talking about pyDev in the eclipse environment. It seems all I need is to get eclipse to point to the brew python so it can see the serial package.

Sounds like it. One way is:

• In Terminal, run "which python2.7" and copy the output.
• "make menuconfig"
• Under "SDK Tool Configuration" -> "Python 2 Interpreter", delete the default name and paste the command output.

This method has the advantage that you can install Python 3 without worrying about breaking the Python 2 support for esp-idf. Unfortunately, you'll have to do it for each project.

The other way is to manipulate the PATH inside Eclipse so your Python directory comes before it's internal pyDev version. I'm afraid I don't know how to do this.

Great day in the morning!
Changing python's path in the interpreter did the trick.

Thank you all.

phando, what exactly did you do to fix this problem? I have exactly the same issue. I can compile from the command line, but when make runs from within Eclipse it seems to use a python version that does not have the serial module installed.
