dplyr异常，非信息性错误summary_all：“错误：不期望这样”吗？

Question

使用我几个月前开发的并且经常使用的脚本，直到最近（〜在过去一周内），我一直面临着dplyr :: summarize_all（）引发的特殊错误的问题。以前有没有人遇到过这种情况，并且在潜在的解决方法方面有一些线索？

我尝试删除/重新安装tidyverse和dplyr，只是更新了我的R版本。

library(tidyverse)

# Generate a dataframe
df <- tibble(
  year = c(rep(2000, 365), rep(2001, 365)),
  day = c(1:730),
  temperature = rnorm(730, mean = 10, sd = 3)
)

# summarize() works fine
df %>%
  group_by(year, day) %>%
  summarize(temp = mean(temperature))

# A tibble: 730 x 3
# Groups:   year [2]
    year   day  temp
   <dbl> <int> <dbl>
 1  2000     1  7.62
 2  2000     2  7.08
 3  2000     3 10.6 
 4  2000     4 11.4 
 5  2000     5 10.1 
 6  2000     6  7.18
 7  2000     7 13.2 
 8  2000     8  8.64
 9  2000     9  9.42
10  2000    10 10.1 
# … with 720 more rows

# summarize_all() and summarise_all() do not
df %>%
  group_by(year, day) %>%
  summarize_all(mean)
