Powerline-daemon giving error libffi.so.7: cannot open shared object file

[Farzad Majidfayyaz]

Hi,

Today when I updated my packages in Manjaro Linux, I'm getting this error when I run powerline-daemon:

Traceback (most recent call last):
  File "/home/farzad/.asdf/installs/python/3.9.7/bin/powerline-daemon", line 23, in <module>
    from powerline.shell import ShellPowerline

ImportError: libffi.so.7: cannot open shared object file: No such file or directory

I have the latest version of powerline installed (2.8.2).

Please let me know if there's any other information I can provide to troubleshoot this.

It seems that you are missing libffi.so.7, perhaps it got removed with your update?

Thank you @PH111P for the quick reply.

Not sure what happened and why it was removed (I have no idea what the library is for 😛 ), but, at least in my Manjaro distribution, I installed aur package libffi7, and it seems to be fine now

PS: putting here the package name in case people face the same issue
PS2: I think the package runs some tests, so it takes a while to install; patience is the key 😅

Closing this as my issue is resolved 🙂
