Unable to create tile (tile) in unity project

The reason for this may be that the 2D Tilemap Editor is missing in the project

操作如下：

Window->package manger (remember to select unity register in the drop-down window) -> find 2D Tilesmap editor and install it

3, you can install it after you find it, and you can create a tile after the installation is complete
