REPL doesn't start on Windows

When I try to start the micropython REPL on Windows (10 in this case, not tested on others), I get a traceback:

File "C:\Users\xxx\AppData\Local\Programs\Python\Python36-32\lib\codecs.py", line 408, in __getattr__
    return getattr(self.stream, name)
AttributeError: 'Out' object has no attribute 'buffer'

When I try to run microrepl.py directly I can get the tracebacks; when I run it via the ‘MicroPython REPL’ menu in PyCharm it flashes an error then disappears.

The closest thing to this I could find online was https://github.com/wendlers/mpfshell/issues/5 which as to do with re-creation of the miniterm. I experimented with removing the two lines referring to Console, and I don’t get that error any more (though the REPL doesn’t work as expected).

Perhaps add that to the requirements list. Can you point me to which areas are OS-specific?

@kaybee335 The issue with REPL shouldn’t be related to Conda or your shell, since PyCharm launches just a Python process.

I’m afraid to debug this issue you have to try to launch the same command outside PyCharm as the plugin does. Use your Conda environment (where you’ve installed the package dependencies when PyCharm showed you a yellow warning about missing pyserial, adafriut-ampy, and docopt.

The command is: /path/to/your/virtualenv/or/conda/python.exe /path/to/your/pycharm/settings/…/microrepl.py your-device-name

Based on #35 I assume that the paths for you are:

C:\Users.…\condaenvs\upython\pythonw.exe C:\Users.….PyCharm2017.3\config\plugins\intellij-micropython/scripts/microrepl.py COM4

Please create new bugs for any issues not related to the problem with starting REPL on Windows like you did for boot.py in #35.
