Installation Directory Requires All or Group Write Permission #30

Closed rcraverii closed 2 years ago

rcraverii commented 2 years ago

GIFTs tagged version 1.3.0 writes to directory in the module installation path which may not be writable by anyone other than the install user.

Steps to reproduce the behavior:

  1. Install the GIFTs software.
  2. Run a script that invokes the GIFTs library as a different user (at least initially). An error results.

It is expected that the software will complete without error.

Below is example output from our test case. The script 'generate_iwxxm' is our custom command line interface to the GIFTs library.

Setting the directory permissions on the directory 'gifts-1.0.0-py3.8.egg' to writable by other users (e.g., 777) allows the application to complete.

Thank you for this report, Rob. Skyfield periodically fetches the latest the JPL ephemeris files to keep them up-to-date. I will look into the destination directory's configuration/properties.
