I’m experimenting because I’m working through the author review part of the second edition of Arduino Software Internals, and the PlatformIO chapter has been updated.
I note that there is a --project-dir or -d option to pio init. However, the operation is inconsitent.
In my first test, I didn’t create the output directory, and it failed, advising me that the output directory didn’t exist. I can cope with that, but it would be nice if it created the output as it creates the src, lib directories anyway, normally.
In my second test, I created the directory and specified it thus:
mkdir fred
pio init -b uno -d fred
That fell over with a lot of red text and Python errors—see below. However, it did create the usual directories and most of platformio.ini—the comments were there but the [uno] environment was missing.
I cleared out and tried again with a relative path.
rm -Rf fred
mkdir fred
pio init -b uno -d ./fred
Same problem, same messages, same output.
Finally, I tested with a full path:
rm -Rf fred
mkdir fred
pio init -b uno -d $PWD/fred
And this worked perfectly.
The output from the failing tests is:
The following files/directories have been created in fred
include - Put project header files here
lib - Put project specific (private) libraries here
src - Put project source files here
platformio.ini - Project Configuration File

============================================================
An unexpected error occurred. Further steps:
* Verify that you have the latest version of PlatformIO using
`python -m pip install -U platformio` command
* Try to find answer in FAQ Troubleshooting section
https://docs.platformio.org/page/faq/index.html
* Report this problem to the developers
https://github.com/platformio/platformio-core/issues
============================================================
The bit about “FileNotFoundError: [Errno 2] No such file or directory: ‘fred/platformio.ini’” seems misleading as it managed to create the file, although I suspect that’s more of a “copy and paste” operation. I suspect it’s trying to open the file to write the environment settings. I’m not a Python programmer but it looks to me like it can’t tell the difference between a full path or a relative one, and I find that hard to believe.
Cheers,
Norm.
