你好 你的问题解决了吗 ?我也遇到了同样的问题 是什么原因呢 怎么解决呢 ?谢谢了
I might be late to actually help you, however, I encountered this problem recently and found a solution. I think it is worthy sharing for future reference for Statalist users. In my case, my variable had a relatively big name, with a lot of characters, and (un)fortunately by sheer chance, I thought about changing it to a smaller name and the error went away. I do not know yet exactly caused in the first place this error in the pvar command, but that small change in the variable name worked for me.
