r - R：运行 stan() 函数得到一些错误：

Question

当我运行 stan() 函数时，我收到关于文件中的错误（con，“r”）的两个错误：无法打开连接和接收器中的错误（类型 =“输出”）：无效连接。顺便说一句，我的 .stan 文件是正确的。请帮忙。

> rstan:::rstudio_stanc("8schools.stan")
8schools.stan is syntactically correct.
> schools_dat <- list(J = 8, 
+                     y = c(28,  8, -3,  7, -1,  1, 18, 12),
+                     sigma = c(15, 10, 16, 11,  9, 11, 10, 18))
> fit_8schools <- stan(file = 'C:/Users/.../Desktop/8schools.stan', data = schools_dat)
The NEXT version of Stan will not be able to pre-process your Stan program.
Please open an issue at
 https://github.com/stan-dev/stanc3/issues 
if you can share or at least describe your Stan program. This will help ensure that Stan
continues to work on your Stan programs in the future. Thank you!
This message can be avoided by wrapping your function call inside suppressMessages().
