Error in hyperglass setup with defined HYPERGLASS_PATH

[k-akashi]

Bug Description

No error occurs selecting a directory for hyperglass from prompt.
But hyperglass setup fails when HYPERGLASS_PATH is defined.
The type of app_path when executing hyperglass setup differs depending on whether or not HYPERGLASS_PATH is defined.
The error message follows:

  File "/usr/local/lib/python3.8/dist-packages/hyperglass/cli/installer.py", line 74, in _scaffold
    ui_dir = self.app_path / "static" / "ui"
TypeError: unsupported operand type(s) for /: 'str' and 'str'

Possible Solution

When retrieving HYPERGLASS_PATH with os.environ.get in the _get_app_path method of the Installer class, it needs to be converted from a string to a path object using pathlib.Path.

Environment

Server

• OS: ubuntu 20.04
• Python Version: 3.8
• hyperglass Version: 1.0.4
