[Exception] if /dev/fd not available
cocoon opened this issue · comments
The lines starting here:
cause an exception on systems where /dev/fd does not exists (a router in my case).
I just surrounded the block with "try".
Error Message:
Traceback (most recent call last):
File "/opt/lib/python3.9/site-packages/sh.py", line 2068, in __init__
inherited_fds = os.listdir("/dev/fd")
FileNotFoundError: [Errno 2] No such file or directory: '/dev/fd'
Thanks for the report!
Which kind of operating system is this, and which version? Does the system have another place it exposes file descriptors?
This is an ASUS RT-AX88U
