Problem with: ImportError: No module named fsevents

[dacz]

I'm trying to run docker-sync but I'm getting error with fsevents.

Please, can you help me what am I doing wrong?

I've installed fswatch and unison via brew and docker-sync via gem (with sudo).

Please, can you help? Thanks!

You miss unox on your host, try to run either

pip install unox

or

sudo pip install unox

[uschtwill]

Easier said than done:

❯ pip install unox
Collecting unox
  Could not find a version that satisfies the requirement unox (from versions: )
No matching distribution found for unox

Help?! :)

Edit:

❯ pip -v install unox

You are using pyenv - you need to fix it. I am using python 2.7, you are using 3.4 - i am not sure if unox is not available for 3.x or whatever, please check the python related docs, i cannot really help with custom python installations, sorry

[uschtwill]

Actually this doesn't seem to be a version issue, https://pypi.python.org/simple/unox/ just returns a 404. There isn't even any version info being transmitted, it looks like there simply is no package called unoxat all... or am I missing something here?

[EugenMayer]

Sorry, my bad. https://github.com/EugenMayer/docker-sync/blob/master/lib/docker-sync/preconditions.rb#L49

You ar missing macfsevents https://github.com/EugenMayer/docker-sync/blob/master/lib/docker-sync/preconditions.rb#L51

unox has been installed most probably using brew - did you?

[uschtwill]

No, I hadn't installed this ominous unox thing. :)

But I just got it to work by running https://github.com/EugenMayer/docker-sync/blob/master/lib/docker-sync/preconditions.rb#L49.

I then tried docker-sync startagain, which then threw the error ImportError: No module named fsevents.

At that point I remembered that I had installed Python 2.7 using pyenv, and that I already had set the local Python in the project directory to 2.7 as well, but that I hadn't installed macfsevents for that Python yet. So I ran the second command you referenced again and lo and behold docker-sync start is now working.

Thank you!

[EugenMayer]

well i added some confusion to the mix, so i guess, we are equal :)

Great that it works, happy syncing!

[uschtwill]

It's all good: ;)

Oh yeah, and I just tried switching back to Python 3.4.4 (pyenv local 3.4.4) with docker-sync startthen throwing:

After doing a pyenv local 2.7 it works again. So yeah, the Python versions does seem to make the difference. :)
