When loading plugin, "ngrok binary was not found. Be sure to call "ngrok.install_ngrok()" first for "ngrok_path""

There seems to be a problem when loading the plugin initially. Here's the error log below:

2020-11-16 19:19:01,783 - octoprint.plugin.core - ERROR - There was an error loading plugin ngrok Traceback (most recent call last): File "/home/pi/oprint/lib/python3.7/site-packages/octoprint/plugin/core.py", line 1114, in load_plugin plugin.load() File "/home/pi/oprint/lib/python3.7/site-packages/octoprint_ngrok/init.py", line 378, in plugin_load plugin_implementation = NgrokPlugin() File "/home/pi/oprint/lib/python3.7/site-packages/octoprint_ngrok/init.py", line 37, in init ngrok.get_version() File "/home/pi/oprint/lib/python3.7/site-packages/pyngrok/ngrok.py", line 359, in get_version ngrok_version = process.capture_run_process(pyngrok_config.ngrok_path, ["--version"]).split("version ")[1] File "/home/pi/oprint/lib/python3.7/site-packages/pyngrok/process.py", line 357, in capture_run_process _validate_path(ngrok_path) File "/home/pi/oprint/lib/python3.7/site-packages/pyngrok/process.py", line 376, in _validate_path "\"ngrok_path\": {}".format(ngrok_path)) pyngrok.exception.PyngrokNgrokError: ngrok binary was not found. Be sure to call "ngrok.install_ngrok()" first for "ngrok_path": /home/pi/oprint/lib/python3.7/site-packages/pyngrok/bin/ngrok

Adding ngrok.install_ngrok() on line 35 of ./__init__.py solved the problem, though I'm not sure this is a valid solution.

[fieldOfView]

ngrok.install_ngrok() should already be called when installing the plugin. Could you check/share your plugin_pluginmanager_console.log?

It's rather strange cause I can't find any error or warning logs. I've set octoprint's logging level to 'DEBUG'.

[fieldOfView]

It turns out the ngrok binary should automatically be downloaded and installed the first time ngrok.connect() is called, so any errors would not show up in the plugin installer log. So the bug at hand is that ngrok.connect() is not the first call to the binary that happens (ngrok.getVersion() is).

[fieldOfView]

Fixed in version 0.3.2. Thanks for the report!
