Deparse issue with semPath

[April Smith]

Hi,

I wrote code to do an SEM using lavaan 6months+ ago.  The code worked beautifully then; I am having issues with it today.  Specifically, I get this error code when running semPaths in semPlot.  Any thoughts on what's wrong today?  I have multiple sem's and plots, and I get this error with all of them.

Error:

Error in deparse(substitute(object)) : 

  no slot of name "version" for this object of class "lavaan"

Error during wrapup: no slot of name "version" for this object of class "lavaan"

Code:

Are you using a development version, or the versions on CRAN?  

sessionInfo()

If the error occurs with the CRAN versions, try the development version of lavaan, in case the issue has already been resolved.

If the error persists, you should try sending your data and syntax to the semPlot developer so he can see what is going wrong.
