pretty table need to be added to mbed-cli requirements.txt

[BlackstoneEngineering]

Problem

On a clean machine I installed mercurial, python and gcc.

Then I installed mbed-cli
pip install mbed-cli

Next I imported a program
mbed import https://developer.mbed.org/teams/mbed/code/mbed_blinky/

followed by
mbed deploy

Next I setup my toolchain and target
mbed config toolchain GCC_ARM and mbed config target K64F

Finally I went to compile the program with mbed compile, and which point the compile promptly terminated because I didnt have prettytable installed.

See output here

C:\Users\ARM\mbed_blinky>mbed compile
Traceback (most recent call last):

Solution

Either add pretty table to the requirements for mbed-cli, or do some magic when importing the mbed 2.0 programs and associated tools. I dont care, i just want the damn thing to work.

To get this thing to work i've now had to install jinja2 and colorama as well as prettytable, all manually. If there is a fix that already exists for this please push it public and mainline as this inability to have tools that work is a critical blocker to making the documentation videos for mbed-cli

[screamerbg]

@BlackstoneEngineering or for this release the guides can point to pip install -r requirements.txt. ARMmbed/mbed-os#2321 was reverted thus for now the tools won't be able to support automatic handling of dependencies

[BlackstoneEngineering]

dude, this isnt for mbedOS, this is for mbed classic

[BlackstoneEngineering]

your tool doesnt work properly for mbed classic

The requirements.txt has been added to the 2.0 tools and now missing requirements are detected when mbed 2.0 program is imported, e.g.
