r语言 - 拟合预言模型时时区错误

Question

我打算使用prophet进行预测。但是当我拟合一个模型时，我得到了错误。我使用来自modeltime.resample:

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))

当我拟合模型时，我得到

错误:CCTZ: Unrecognized timezone of input vector: "GMT">

我尝试重新安装rstan和prophet包，但错误重复。

我删除并重新安装了润滑包。现在它成功了!
