model issue

[h-alani]

foi <- stan_model("Seromodel_lambda1.stan")
Error in stanc(file = file, model_code = model_code, model_name = model_name, :
0
Internal compiler error:
TypeError: e.charCodeAt is not a function

This should never happen. Please file a bug at https://github.com/stan-dev/stanc3/issues/new
and include this message and the model that caused this issue.

I received the above error after running the code. Any help, please?

Hi @h-alani -- We're sorry you ran into this. This is an issue with rstan and their javascript interpreter. We don't believe there is anything more stanc3 can do.

I have realized that the error I received below only occurs after updating my R and R studio. I ran the same code on previous versions and it worked. How do I fix this, please?

foi_accra <- stan_model("Seromodel_lambda1.stan")
Error in stanc(file = file, model_code = model_code, model_name = model_name, :
parser failed badly; maybe try installing the V8 package
