Updating Anaconda fails: Environment Not Writable Error

Question

I\'m trying to update Anaconda and its packages using conda update --name root conda, but it fails every time.

Error message : Environme

Answer 1

I had installed anaconda via the system installer on OS X in the past, which created a ~/.conda/environments.txt owned by root. Conda could not modify this file, hence the error.

To fix this issue, I changed the ownership of that directory and file to my username:

sudo chown -R $USER ~/.conda
