Python error exporting from mbed CLI to LPC1768 MCUXpresso

I have an mbed project that compiles and flashes fine using mbed CLI. I build with this command:

mbed compile --target lpc1768 --toolchain GCC_ARM

And I can then flash it using the MCUXpresso command line tools. Now I'd like to bring the project into MCUXpresso so I can use the debugger. When I do that I get an python error:

$ mbed export -i mcuxpresso -m lpc1768 -v

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

I'm using the CLI on macOS, and I installed it using the macOS installer. I've done all of this just today, so everything should be up-to-date. Python version in the CLI shell is Python 2.7.14 :: Anaconda, Inc.

any help would be appreciated, thanks steve

If it fit to your project try to use Python 3.7 it seems to appear because of lack of library attributes. At https://www.python.org/downloads/ you can download necessary version totally free for any OS from this official site. If this won't help you can ask for assignment help in any time from support

I don't know how to put a new python version into the mbed CLI. And, I think it should work as a package (CLI environment and the bundled python). However I did fix the problem by changing:

self.libraries = libraries

to

self.libraries.append(libraries)

at the referenced line 85.

Both self.libraries and libraries are empty lists, so it doesn't really matter.
