我正在尝试安装tidyr的开发版本。当我尝试devtools::install_github("tidyverse/tidyr")或remotes::install_github("tidyverse/tidyr")时，出现以下错误：
> devtools::install_github("tidyverse/tidyr")

These packages have more recent versions available.
Which would you like to update?
1: All
2: CRAN packages only
3: None
4: rlang (0.3.4 -> 18856f22a...) [GitHub]
5: ellipsis (0.1.0 -> 9908b24a2...) [GitHub]
Enter one or more numbers separated by spaces, or an empty line to cancel

我已按照警告提示删除00LOCK-rlang，然后重试。和以前一样，我被问到要更新哪些软件包，然后选择All。这次，当我尝试更新rlang时收到以下错误：

使用source("https://install-github.me/r-lib/rlang")解决了问题，但是为什么devtools::和remotes::install_github()失败了？

我也遇到了这个问题。请注意[...]\rlang\libs\x64\rlang.dll: Permission denied。当前的R会话不允许访问这些文件。为了避免这种情况，请通过Rgui.exe在Windows搜索中搜索Rgui或通过Win+Q打开C:\Program Files\R\R-3.5.3\bin\x64\Rgui.exe。右键单击并按Run as administrator，然后执行与以前相同的操作。
您也可以在管理模式下运行RStudio。

我找到了一个略有不同的解决方案。
C:\...\R\win-library\3.5\rlang移动到另一个文件夹（该目录中没有rlang文件夹）install.packages("rlang")
