Make a file writable in order to add new packages
提问by angs
I use Rstudio and try to add new packages through command console.
我使用 Rstudio 并尝试通过命令控制台添加新包。
It fails to install it for this reason
由于这个原因它无法安装
install.packages("devtools"); devtools::install_github("hadley/rvest")
Warning in install.packages :
'lib = "C:/Program Files/R/R-3.2.1/library"' is not writable
Warning in install.packages :
cannot create dir 'C:\Users\myuser', reason 'Permission denied'
Error in install.packages : unable to create ‘C:/Users/myuser/Documents/R/win-library/3.2'
Error in loadNamespace(name) : there is no package called ‘devtools'
How can I make this file writable?
我怎样才能使这个文件可写？

Changing the security setting on the R folder to "full control" fixed this for me. See the third posting down at this link for step by step instructions: Unable to update R packages in default library on Windows 7
将 R 文件夹上的安全设置更改为“完全控制”为我解决了这个问题。有关分步说明，请参阅此链接上的第三个帖子：无法更新 Windows 7 上默认库中的 R 包

I ran into this problem. The issue for me was using single quotes instead of double quotes. Using install.packages("foo")worked fine, whereas install.packages('foo')caused this issue.
我遇到了这个问题。我的问题是使用单引号而不是双引号。使用install.packages("foo")工作正常，而install.packages('foo')导致此问题。

As i have found out that disabling the Ransomware protection on Window Defender allows me to write in the directory.
正如我发现在 Window Defender 上禁用勒索软件保护允许我在目录中写入。
This solved the problem. Hope it works for you.
