【问题描述】：

我正在尝试安装 tidyr 的开发版。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")
Downloading GitHub repo tidyverse/tidyr@master

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
1: 1

我按照警告的建议删除了00LOCK-rlang，然后重试。和以前一样，我被问到要更新哪些包，我选择All。这次尝试更新rlang时出现以下错误：

第二次尝试后的会话信息：

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

【解决方案1】：

我也遇到过这个问题。注意[...]\rlang\libs\x64\rlang.dll: Permission denied。当前的 R-session 不允许访问这些文件。要避免这种情况，请通过Win+Q 或C:\Program Files\R\R-3.5.3\bin\x64\Rgui.exe 在Windows 搜索中搜索Rgui 来打开Rgui.exe。右键单击并按Run as administrator，然后像以前一样做同样的事情。

您也可以在管理模式下运行 RStudio。

【讨论】：

我遇到了同样的问题。以管理员身份运行 R 对我不起作用。以管理员身份运行 RStudio 也不起作用。以管理员身份运行 Rgui 即可解决问题。我不明白原因，但它起作用了。
谢谢@Mossa，我不会想到使用 gui - 为什么安装它与 RStudio 之间会有区别？我曾尝试以管理员身份运行 RStudio，但这对我也不起作用。

【解决方案2】：

我找到了一个稍微不同的解决方案。

以管理员身份打开 Rgui.exe。我认为您实际上不需要以管理员身份打开 Rgui.exe，但我这样做了，我会留下它。
将 C:\...\R\win-library\3.5\rlang 移动到另一个文件夹（在该目录中不保留 rlang 文件夹）
install.packages("rlang")
关闭Rgui
开始新的（正常）会话并享受吧！
