5.4.8后输入/bpt就开始报错，虽然可以直接改lua但是总是麻烦。到处转了圈找了个解决方案~就来分享一下。  
用记事本打开interface/addons/BalancePowerTracker/ModuleLoader.lua
 
下翻到到底
 
从--/slash command开始到底替换成下面的代码，然后保存rl就好了
 
--/slash command
SLASH_BALANCEPOWERTRACKER1,SLASH_BALANCEPOWERTRACKER2= '/balancepowertracker','/bpt';
function SlashCmdList.BALANCEPOWERTRACKER(msg, editbox) --Slash command function
local reason = select(6,GetAddOnInfo("BalancePowerTracker_Options"));
local loaded;
 
if not reason then
loaded,reason = LoadAddOn("BalancePowerTracker_Options") 
end
 
if not loaded then
local msg = "|c00a080ff"..BalancePowerTracker.name.."|r: Couldn't load: ".."BalancePowerTracker_Options"
 
local localizedReason = reason and _G["ADDON_"..reason]
 
if localizedReason then
msg = msg..": "..localizedReason..".";
else
msg = msg.."."
end
print(msg);
return
end
 
InterfaceOptionsFrame_OpenToCategory(BalancePowerTracker.name)
end
