DTC version unsupported error #west


On a new Ubuntu install, I'm having this issue with Zephyr using West.  It's also referenced in this issue, but the fix mentioned there didn't work for me:


$ west build -b nrf51_pca10031
-- west build: build configuration:
       source directory: /home/hp1/zephyrproject/zephyr/samples/hello_world
       build directory: /home/hp1/zephyrproject/zephyr/samples/hello_world/build
       BOARD: nrf51_pca10031 (origin: command line)
-- west build: generating a build system
Zephyr version: 1.14.99
-- Selected BOARD nrf51_pca10031
-- Found west: /home/hp1/.local/bin/west (found suitable version "0.5.7", minimum required is "0.5.6")
CMake Error at /home/hp1/zephyrproject/zephyr/cmake/extensions.cmake:1324 (message):

      The version was found to be 1.4.5                                  
      But the minimum supported version is 1.4.6                       
      See https://docs.zephyrproject.org/latest/getting_started/

-- Configuring incomplete, errors occurred!

I did try the two environmental variables, which are now part of the Zephyr instructions, but the problem persists.

export ZEPHYR_SDK_INSTALL_DIR=$HOME/zephyr-sdk-0.10.1

I'm unsure how to go about fixing the DTC version issue.
