ImportError: No module named pyocd.tools.gdb_server

[yennster]

I used pip install -U pyocd to upgrade my pyocd version today.

I try to run a GDB server with pyocd-gdbserver and I get the following error output:

~ $ pyocd-gdbserver
Traceback (most recent call last):
  File "/usr/local/bin/pyocd-gdbserver", line 7, in <module>
    from pyocd.tools.gdb_server import main
ImportError: No module named pyocd.tools.gdb_server

I am using pyocd version 0.13.2 and arm-none-eabi-gdb version GNU gdb (GNU Tools for Arm Embedded Processors 7-2018-q2-update) 8.1.0.20180315-git

In order to run a pyocd-gdbserver I need to downgrade pyocd to version 0.12.x

Hi @yennster, what OS are you using, and what pip and setuptools versions? You might need to uninstall pyOCD and reinstall.

The package name was changed from "pyOCD" to "pyocd" in order to be compliant with Python naming standards. Unfortunately, on case-insensitive filesystems, upgrading may not correctly rename the folder. What's weird is that I tried this on macOS, Windows, and Linux (Ubuntu) and it seemed ok (after some initial trouble in 0.13.0). Maybe it's and older pip or setuptools? I'll try reproducing it once I know your OS and versions.

got the same issue, running on windows 10. With pyocd 0.13, mbetgt fiails. A 'mbedgt --version' throws an error that pyOCD.board is missing.
Downgrading to 0.12 fixes the problem, upgrading to 0.13.2 raises the problem again.

D:\Projects\Sn\LocalGit\test\mbed-SDIO-V2>mbedgt --version
mbedgt: Not all required Python modules were imported!
mbedgt: No module named pyOCD.board

@flit Here's my version info:

• Mac OS 10.14.1
• pip 18.1
• python 2.7.15
• setuptools 39.2.0

This looks like it might be caused by conflicting version requirements between htrun (used by greentea) and pyOCD. I'm working on fixing these tools so they can use the latest pyOCD.

@yennster I just tried reproducing your upgrade problem with no luck. I created a virtualenv with exactly the same versions as you have, installed pyOCD 0.12.0, then ran pip install -U pyocd to upgrade to the latest. pyocd-gdbserver still runs fine. So I'm not sure what the problem you are seeing could be caused by! Can you try using a virtualenv?

@JojoS62 In the meantime, I recommend using two virtualenvs. One for debugging with pyOCD, and one for running greentea. I've moved the issue you are having to #467 since it's different from @yennster's upgrade problem (but with similar errors).

@yennster Is this still an issue for you? I recently helped a partner with a similar issue where he had to manually rename the installed pyOCD package directory to pyocd to get it to work, but that was on Windows.

Issue is resolved now after I updated to the latest pyOCD pip install -U pyocd
