UndefinedEnvPlatformError: Please specify platform for 'esp' environment

I’m receiving this error every time I run or test with platformio on an environment that is not the one mentioned in the error. I have two environments in my platformio.ini file, native and esp. The actual builds and tests run perfectly for both environments, but this error always shows when I run/test the native environment. A google search of "UndefinedEnvPlatformError" "platformio" returns only 3 results, none of which resolve this issue for me.

Any tips appreciated, thanks!

platformio version 6.1.15 running in the esphome/esphome docker container.

Please show the content of your platformio.ini

Here’s my .ini file. The project is an esphome external component, and this .ini file is for running tests. This file, and all other test files are located in a directory <external-component-dir>/test/.

The command I’m running is pio test --without-uploading -c test/platformio.ini -e native

Thanks!

There are a few things in here to think about, but not related to the error you mentioned.

Can you post the whole error message?

5

But this is true: The esp environment doesn’t have the platform set, like

platform = espressif32
6

It is there, look at the 4th and 5th line from the end of the esp env:

7

Intersting. But I’ve never seen it written in author/name@^version like that. I would have written

platform = espressif32@^6.1.0
8

Me too :slight_smile: But it works… I’ve tested it and I think it’s a valid notation.

@sivar2311 and @maxgerhardt, thanks for having a look!

Unfortunately, the topic title is the entire error. I’ll paste the output below. I just noticed that this error only shows if I add the verbosity flag(s) -v to the pio test command. Without the flag(s), there are no errors printed to the output. Here are examples of both.

Note that last line of the output. Also note that this error only appears when I run the native environment, not when I run the the esp environment.

Re my .ini file, I figured there would be other issues unrelated to this error. Some of the lines were copied verbatim from the esphome-generated platformio.ini file of a project that incorporates this external component (that’s where the platformio/espressif32@^6.1.0 came from). I’m happy to hear your thoughts and critique, thanks!

Hm… :thinking:

One thing I don’t have is the extra script. So i commented it out for my test.
Can you share the content of the test/post_build.py ?

Ah, yes! It didn’t occur to me that could be part of the issue. Here it is.

Ok, now i have several other errors as this scripts starts downloading some packages etc etc. I have never seen something like this before.

What is the goal here?
Did you write this?

All LDF modes beside of chain are more or less buggy / broken.
Change your project to work with chain in mode strict
