Python error installing pyOCD for CMIS-DAP upload and debug

[Torino1564]

Hi, Im trying to run a project on a FRDM-K64F board and I get an error when trying to upload or debug it with the CMIS-DAP protocol. This is the platformio.ini file:
[env:frdm_k64f] platform = freescalekinetis board = frdm_k64f framework = mbed lib_deps = adafruit/Adafruit Motor Shield V2 Library@^1.1.3 mbed-components/MotionSensor@0.0.0+sha.226520fc09bf br3ttb/PID@^1.2.1 upload_protocol = cmsis-dap debug_tool = cmsis-dap

And this is the error that I get:

ERROR: Failed to build 'pyyaml' when getting requirements to build wheel
Installing Python dependencies for pyOCD...
Error: Couldn't install dependencies for pyOCD!
*** [upload] Error 1

The error gets fixed if I switch to the mbed upload protocol, however debugging still brings up the same error.

Ive already tried installing pyOCD in the virtual environment and it finishes with no issues, but then for some reason it tries to install it again when uploading and fails with the previous error.
