Roxygen警告“无法打开连接” “权限被拒绝”；

问题描述：

我正在使用roxygen2，由于某种原因我无法使其运行。

我已经尝试过：

I'm working with roxygen2 and for some reason I can't get it to run.
I've tried:

> devtools::load_all()
> devtools::document()

结果是：

Updating xxxx documentation 
Loading xxxx
First time using roxygen2. Upgrading automatically... 
Writing NAMESPACE 
Error in file(con, "r") : cannot open the connection 
In addition: Warning message: In file(con, "r") :   cannot open file 
'C:\Users\xxxxxxx': Permission denied

I还尝试过：

> roxygen2::roxygenise()

收益：

Loading xxxx
Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") :
  cannot open file 'C:\Users\xxxxxxxx': Permission denied

我尝试安装6.1.0和6.0.1版本的roxygen，结果相同。
有什么解决方案吗？谢谢。

I've tried installing the 6.1.0 and 6.0.1 versions of roxygen, with same results. Any solutions? Thanks.

就此，即使在使用上述解决方案并更新到 roxygen2 （7.0.1）的最新版本，我一直遇到相同的错误。经过一些调试后，我发现在函数之一中，函数文档中有一个空的＃’行。省略空行后，便可以对函数进行充氧并创建文档。希望这会有所帮助！

Just to follow-up on this, even after using the solution above and updating to the most updated version of roxygen2 (7.0.1) I kept getting the same error. After some debugging, I found that in one of my functions I had an empty #' line in the documentation of the function. Once I omitted the empty line, I was able to run roxygenize my functions and create the documentation. Hope this helps!
