Error: Directory not owned by the current user and cache has been disabled.

Symptom

When starting a workspace session, kicking off a run, or building a custom compute environment, you may see the following message in the console output:

The directory '/home/ubuntu/.cache/pip/http' or its parent directory 
is not owned by the current user and the cache has been disabled. 
Please check the permissions and owner of that directory. If 
executing pip with sudo, you may want sudo's -H flag.
The directory '/home/ubuntu/.cache/pip' or its parent directory 
is not owned by the current user and the cache has been disabled. 
Please check the permissions and owner of that directory. If 
executing pip with sudo, you may want sudo's -H flag.

Solution

While it is formatted as an error, this is simply a warning and will not interfere with your runs or workspace sessions.

Note: Using sudo's -H flag can cause errors, so don't add it to make the warning go away. 

This warning is scheduled to be silenced in future releases, and normally shows up when installing python packages using the requirements.txt file, or when building custom compute environments..
