Pip installation error on Ubuntu

Describe the bug The upgrade to mythril 0.18.10 fails on Ubuntu with the following error:

$ pip3 install mythril -U
Collecting mythril
  Using cached https://files.pythonhosted.org/packages/ac/c4/a258e1472f29e0866d6a82f320df17b69e1b45e552e7c7cf46194a566e70/mythril-0.18.10.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-qa5hgytb/mythril/

Same error when running setup.py manually:

ubuntu:~/myth/mythril-0.18.10$ python setup.py 
Traceback (most recent call last):
  File "setup.py", line 15, in <module>
    exec(open(version_path, 'r').read())
TypeError: invalid file: PosixPath('/home/ubuntu/myth/mythril-0.18.10/mythril/version.py')

The file mentioned in the error message exists & is readable though:

$ cat /home/ubuntu/myth/mythril-0.18.10/mythril/version.py
# This file is suitable for sourcing inside POSIX shell, e.g. bash as
# well as for importing into Python
VERSION="v0.18.10"  # NOQA

On my Mac, it worked without issues.

@rocky, this might have something to do with the latest changes in #351?

Ok. I see what’s up. I bet you ran this on Python version 3.5.x (or more precisely < Python 3.6) where open() doesn’t accept a Path type.

One simple fix is to change:

exec(open(version_path, 'r').read())

to:

exec(open(str(version_path), 'r').read())

but perhaps this error has some blessings in disguise. (Or at least I hope you take it that way 😃 )

Previously when I was checking to see if this worked for Pypy, I recall reading that Mythril needs 3.6 or later. Is 3.5 acceptable?

Our setup.py suggest yes here.

However it also says here that Python 2x, 2.7, 3x, 3, and 3.4 are allowed in addition. And no mention of 3.6 or 3.7.

So which versions do we support?

After understanding that, I would be happy to correct all of the parts of setup.py to make them consistent in the next fix.

Thanks.

Closing this as the original issue seems to be fixed. Thanks @johnbender for confirming. Not sure if the mac os thing has been solved, if not feel free to open another issue 😄

@JonHaas Thanks for the info! 👍 Hope that helped with @stuardo3191’s issue. We’re planning on supporting 3.7 as well in the future
