Question

我试图在tidyverse包中使用R中的read_csv，但我总是收到这条消息：

> read_csv(readr_example("mtcars.csv"))
Error in date_names_lang(date_names) : 
  cannot open file '~/R/win-library/3.4/readr/R/sysdata.rdb': No such file or directory

文件和目录确实存在：

> list.files("~/R/win-library/3.4/readr/R/")
[1] "readr"       "readr.rdb"   "readr.rdx"   "sysdata.rdb" "sysdata.rdx"

我是最新版本的R和tidyverse：

你有什么建议吗？

Answer 1

我遇到了同样的问题。我重新启动了R，重新安装了readr并且它有效。这里有更多链接可能会有所启发：

Answer 2

我在运行 TCGAbiolinks 时也遇到了这个问题。

除了 idecico 的建议之外，我发现在 tidyverse 等其他软件包之前通过 library(readr) 加载 readr，解决了该问题（基于 mrscholz 在以下 github 页面上的评论：https://github.com/tidyverse/tidyverse/issues/46）

R：read_csv错误，＆＃39; sysdata.rdb＆＃39;：没有这样的文件或目录
