编写1602时，在加载库中又安装了LiquidCrystal.h库文件。编译结果出现错误，对应多个库

这个是错误信息

这个是我新添加的库文件，添加过这个后他就出现这个错误了

这个是错误信息
Arduino:1.8.2 (Windows 7), 开发板："Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

"LiquidCrystal.h" 对应多个库

谢谢，我知道了  这个LiquidCrystallcd(12,11,10,9,8,7,6,5,4,3,2);   应该写成
LiquidCrystal lcd(12,11,10,9,8,7,6,5,4,3,2);   不过还是想知道怎么卸载从加载库中安装的文件

自带的库需要在IDE安装文件夹下的libraries里手动删除
