First excuse my bad english.
Im new at platformio, so i create a project but i cant open it .
In other word, i can’t see the folder project (src, lib …) in work space.
That looks like a bug introduced with the latest PlatformIO release. I’m experiencing the same.
The project has been created. It’s just not added to the workspace. It will be created in Documents / PlatformIO / Projects. This applies to both Windows and macOS and possibly to Linux as well.
The workaround is to add it manually:
Click File / Add Folder to Workspace… in the menu
Navigate to the project location and select the project
Click “Add”
The project now appear in the workspace (Explorer view).
