The overall installation logic is divided into: data configuration and installation logic.
1. Data configuration
Creating a class (parameters such as reality, hidden objects, dependent items and dependent items, tools used, parts taken at installation, methods performed before and after steps, etc.) that is sufficient to carry all the contents of each step, and using the class as a data configuration class.
2. Installation logic

2_9 traversing the dependent item of the current step, judging whether the dependent item of the dependent item is executed completely, and if so, adding the dependent item into an installable step dictionary;
2_10, if there is an or relationship, judging the step or the dependent items, if there is a judgment whether they are already installed, if not, adding them into an installable step dictionary;
2_11, then performing 2_6, and cycling until the installable step is empty, i.e. all steps are installed, and the installation is completed.
