hdino · 2021-08-02T07:18:04Z

Problem Description

Spyder won't start due to a plugin KeyError. A spyder --reset doesn't solve the problem.

What steps reproduce the problem?

Start spyder 5.1.0 or git 48b9305.

What is the expected output? What do you see instead?

Spyder should start successfully. Instead, the following errors are shown.

Hey eveyone, thanks for reporting. I'm taking a look at this problem and will try to release 5.1.1 with a fix for it as soon as possible.

Thanks for your patience.

@ccordoba12, the first traceback for @mscheltienne, @a-allard, and @AndrewAmmerlaan, are result of an undeclared dependency on the Application plugin in the Tours plugin.

spyder/spyder/plugins/tours/plugin.py

Line 35 in 97a9961

OPTIONAL = [Plugins.MainMenu]

spyder/spyder/plugins/tours/plugin.py

Lines 57 to 69 in 97a9961

    
           @on_plugin_available(plugin=Plugins.MainMenu) 
        
           def on_main_menu_available(self): 
        
               mainmenu = self.get_plugin(Plugins.MainMenu) 
        
               docs_action = self.get_action(

Note the dependency on line 63.

#16127 will fix these issues. The OP may have similar solution.

Digging in a bit further into the second error I found I could spyder to start if I modified registery.py (api/plugin_registration/registry.py) line 222 to be:

if self.plugin_availability.get(plugin, False) and plugin_name != 'application':

It was:

if self.plugin_availability.get(plugin, False):

I don't know why this works I just know it gets spyder running on my machine.

@ccordoba12, #16130 appears to resolve all issues that I ran into for the macOS application.
