I am getting an InvalidArchiveError in anaconda prompt when I am trying to install spacy. How to solve it?

Question

InvalidArchiveError('Error with archive C:\Users\Sahaja Reddy\Anaconda3\pkgs\openssl-1.1.1g-he774522_0.conda. You probably need to delete and re-download or re-create this file. Message from libarchive was:\n\nCould not unlink (errno=22, retcode=-25, archive_p=1873471744752)')

Answer 1

I had this same problem - I had an IPython instance open that was holding onto the Openssl handle open so I wasn't able to delete the Openssl folder as mentioned above by Prayson. After closing all of my IPython & Python instances through the command prompt, or entering the following in a command prompt:

TASKKILL /F /IM python.exe

I was then able to run

conda install -c conda-forge libarchive

(as mentioned previously) to update the openssl library without having to actually delete anything. After that, everything went back to normal.

Answer 2

The better approach is to do a cleanup

conda clean --all
