安装Enscape加载失败，怎么解决？

载入文件 C:/Users/Administrator/AppData/Roaming/SketchUp/SketchUp 2018/SketchUp/Plugins/enscape/loader.rb 时出错
Error: D:/SU/Tools/extensions.rb:197:in `require'
D:/SU/Tools/extensions.rb:197:in `load'
C:/Users/Administrator/AppData/Roaming/SketchUp/SketchUp 2018/SketchUp/Plugins/enscape.rb:9:in `register_extension'
C:/Users/Administrator/AppData/Roaming/SketchUp/SketchUp 2018/SketchUp/Plugins/enscape.rb:9:in `<top (required)>'
 
每次打开SU就会弹出这个，求解答。
