Configuration

Operating system:

OSX 12.4

PlatformIO Version (platformio --version):

6.1.6a4 (though also applies to 6.1.3)

Description of problem

When two libraries both list each other as dependencies in their library.json manifests, pio pkg list and pio pkg uninstall both throw RecursionError: maximum recursion depth exceeded while calling a Python object errors.

Steps to Reproduce

1. Create a new project with the following platformio.ini file:

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
lib_compat_mode = strict
lib_ldf_mode = chain+
lib_deps = khoih-prog/[email protected]

(The key detail here being that the libraries WiFiMulti_Generic and WiFiNINA_Generic both list each other as dependencies in their library.json manifests)

2. Install the dependencies with pio pkg install
3. Cause the error via pio pkg list or pio pkg uninstall -l WiFiMulti_Generic

Actual Results

Both commands eventually fail, throwing a RecursionError: maximum recursion depth exceeded while calling a Python object exception.

Expected Results

Ideally, the libraries should be removed / listed as expected.

If problems with PlatformIO Build System:

The content of platformio.ini:

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
lib_compat_mode = strict
lib_ldf_mode = chain+
lib_deps = khoih-prog/[email protected]

Thanks for the report. Please re-test with pio upgrade --dev.
