error when importing from mbed

Emmanuel Dupouy

Hi,

I was trying to import a project from mbed online compiler to uvision5. So, I followed this tutorial: http://www.keil.com/appnotes/files/apnt_207_v2.0.pdf
But when I executed the command:
mbed export -i uvision5 -m disco_l072cz_lrwan1
it returned the error "No module named jsonschema"

You can see the execution here:

[mbed] Working path "C:\Users\emman\GoogleDrive\Keil\DISCO-L072CZ-LRWAN1_blink_leds" (program)
Traceback (most recent call last): File "C:\Users\emman\GoogleDrive\Keil\DISCO-L072CZ-LRWAN1_blink_leds\.temp\tools\project.py", line 19, in <module> from tools.export import ( File "C:\Users\emman\GoogleDrive\Keil\DISCO-L072CZ-LRWAN1_blink_leds\.temp\tools\export\__init__.py", line 29, in <module> from ..config import ALLOWED_FEATURES File "C:\Users\emman\GoogleDrive\Keil\DISCO-L072CZ-LRWAN1_blink_leds\.temp\tools\config\__init__.py", line 31, in <module> from jsonschema import Draft4Validator, RefResolver

Tip: You could retry the last command with "-v" flag for verbose output

Anyone have an idea please?

    Hi,

    I finally discovered the reason of this error. It is necessary to install a package jsonschema.
    In a terminal: pip install jsonschema

    Then I had another error: File "c:\Users\emman\GoogleDrive\Keil\DISCO-L072CZ-LRWAN1_blink_leds\.temp\tools\project.py", line 145, in export notify.info("Using targets from %s" % targets_json)
    AttributeError: 'NoneType' object has no attribute 'info'
    [mbed] ERROR: "C:\Python27\python.exe" returned error. Code: 1 Path: "c:\Users\emman\GoogleDrive\Keil\DISCO-L072CZ-LRWAN1_blink_leds" Command: "C:\Python27\python.exe -u c:\Users\emman\GoogleDrive\Keil\DISCO-L072CZ-LRWAN1_blink_leds\.temp\tools\project.py -i uvision5 -m disco_l072cz_lrwan1 --source ."

    To resolve it, I only comented line 145 of project.py file.
    After that, all worked fine.
