- Python 3.6.4,
- clize 4.0.3,
- logbook 1.1.0.
2.2. Project
https://github.com/Kristinita/SashaPythonTest
my simple program check, contains <body> in .txt files in folder or no.
It that I want in #35.
2.3. Folders
I have 2 folders with similar content:
SashaPythonTestOnDiskC— on disk C,SashaPythonTestOnDiskD— on disk D.
Content of SashaPythonTestOnDiskC and SashaPythonTestOnDiskD folders:
C:\SashaPythonTestOnDiskC>tree /f
C:.
BodyExists.txt
NoBody.txt
BodyExists.txt file:
<body>
NoBody.txt file:
No
3. Steps to reproduce
I install my project:
setup.py install
I run command sashatest in console.
4. Expected behavior

ValueError: path is on mount 'C:', start on mount 'D:'
Thanks.
Having the same Windows issue. I'm using a setup.py entry-point (installed in my conda environment on C:, available in my PATH envvar), which is executed from a folder on the D: drive.
The problem is in runner.py:303, which is invoking rel = os.path.relpath(path). Executing relpath when the current directory is on D: but path starts with C: will raise the exception.
I fixed the issue by patching my runner.py file, changing line 303 to this:
try:
rel = os.path.relpath(path)
except ValueError:
return basename
I think there may also be some other Windows-specific bugs, e.g. the if which(basename) == path: check in line 301 might fail for windows executables, where .EXE and .BAT are added to the executable. But that wasn't relevant in my case.
