Installation Issue with PyOTP

I attempted an upgrade home-assistant today but during up-start I get:

2019-11-11 09:03:05 ERROR (SyncWorker_1) [homeassistant.util.package] Unable to install package pyotp==2.3.0: ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: ‘INSTALLER’
Consider using the --user option or check the permissions.
2019-11-11 09:03:05 ERROR (MainThread) [homeassistant.bootstrap] Home Assistant core failed to initialize. Further initialization aborted

I’m using a Raspberry Pi. I’m not running home-assistant as ‘root’.

Hi @jtk,
have you found a solution to this problem?
