适用预言家模型时时区误差

Question

我计划用先知来预测。但当我符合一个模型，我会收到错误。我使用modeltime.resample中的示例：

library(dplyr)  
library(lubridate)  
library(parsnip)  
library(rsample)  
library(timetk)  
library(modeltime)  

m750 <- m4_monthly %>% filter(id == "M750")

splits <- initial_time_split(m750, prop = 0.8)

model_spec <- prophet_boost(
    learn_rate = 0.1
) %>%
    set_engine("prophet_xgboost")

model_fit <- model_spec %>%
    fit(log(value) ~ date + as.numeric(date) + month(date, label = TRUE),
        data = training(splits))

当我适合模特的时候

错误: CCTZ:输入向量的未识别时区："GMT“

我尝试重新安装rstan和先知包，但是错误重复。

我删除并重新安装了lubridate软件包。现在起作用了！
