已解决，谢谢！
In practice, I've seen this error come up a number of times. It can occur because you have incorrectly specified a variable as latent that you wanted to be observed. However, more commonly, it is the result of giving an inappropriate variable to a latent variable. Specifically, it is relatively easy to give a name to a latent factor that is the same as an observed variable in your data file.

For example, one time I had some personality variables in a dataset and the extraversion items were called E1, E2, E3, and so on. These are common names for residuals. So when giving residuals these names, there was a conflict with the names in the data file. Another even more common cause is when you name a latent factor an appropriate name (e.g., selfesteem, extraversion, jobsatisfaction, etc.) and you have already created a scale score in your data file with the same name. This also causes the conflict.

The basic solution is just to give the latent variable a unique name that doesn't conflict with one in the data file. So for example, name the variable selfesteem_factor rather than selfesteem if you already have a variable called selfesteem.

你好，请问这个问题最后是怎么解决的？
我也碰到了这个问题

是怎么解决的呢

如果使用的是sav文件，sav文件里有重名的也不行
