Conda won't update packages

If I try to update any package in conda, regardless of environment, I get an 'image not found' error. Here is the full error message. It just started doing this today, I haven't installed anything new or changed anything that I'm aware of. Anyone know how to fix?

The comment from HereHere on an earlier answer worked perfectly for me. I ran:

conda install -c conda-forge --force-reinstall libffi

in my (base) conda environment and the problem was resolved.

I came across this issue on my Mac when I updated my conda version. It looks like something gets messed up when you update your conda version. So, I removed my previous installation of Anaconda and reinstalled it and error went away.

I'd say definitely try reinstalling your Anaconda or miniconda first before going down the messy route of installing libffi and what not.

It's dependency error caused by libffi. Go to /Users/<user_name>/anaconda3/lib, link existing, higher version libffi as libffi.6.dylib. In my case, this is

ln -s libffi.7.dylib libffi.6.dylib

I had the same issue (on Mac) and took the opportunity to reinstall Miniconda with the following steps. Quick process, works fine now.

  • Delete folder with rm -rf ~/miniconda3.
  • Reinstall using bash installer (pkg installer doesn't seem to be working).
  • Rebuild environments per previous.

use homebrew install libffi 

$ brew install libffi
...
For compilers to find libffi you may need to set:
  export LDFLAGS="-L/usr/local/opt/libffi/lib"

then run 

$ cp /usr/local/opt/libffi/lib/libffi.6.dylib /Users/matthewthomas/anaconda3/lib/

I fixed mine in this way on macOS 10.15.4
