问题
My Spyder Project Explorer normally shows a project and its files, but I recently deleted a project and made the project explorer space empty. I am trying to make the Project Explorer show my existing projects or a new project, but when i try to do that it gives me the error "Project not a Spyder project". How can i restore my Spyder project explorer to show existing or new projects?
回答1:
You need to go to the Projects menu, and select the option called New Project.
Then you need to select the option called Existing directory, choose the directory where your project is located at in the Location field and finally press Create.
That will automatically show your project in the Project Explorer.
