c++ - 错误 : failed to lock directory 'C:/Program Files/R/R-3.0.2/library' for modifying when installing RStan in Rstudio in Windows 7

Question

我正在尝试根据 https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started 安装 RStan

我使用的是 Windows 7、RStudio 0.98.501 和 R x64 3.0.2

我成功地安装了内联包和 Rcpp。

C++测试结果如下:

> src <- ' 
+   std::vector<std::string> s; 
+   s.push_back("hello");
+   s.push_back("world");
+   return Rcpp::wrap(s);
+ '
> hellofun <- cxxfunction(body = src, includes = '', plugin = 'Rcpp', verbose = FALSE)
cygwin warning:
  MS-DOS style path detected: C:/PROGRA~1/R/R-30~1.2/etc/x64/Makeconf
  Preferred POSIX equivalent is: /cygdrive/c/PROGRA~1/R/R-30~1.2/etc/x64/Makeconf
  CYGWIN environment variable option "nodosfilewarning" turns off this warning.
  Consult the user's guide for more details about POSIX paths:
    http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
> cat(hellofun(), '\n')
hello world 

我认为“hello world”意味着我正确安装了 C++。

然后我输入以下代码:

> Sys.setenv(R_MAKEVARS_USER = "foobar")
> options(repos = c(getOption("repos"), rstan = "http://wiki.rstan-repo.googlecode.com/git/"))
> install.packages('rstan', type = 'source')

Warning in install.packages :
  installation of package ‘rstan’ had non-zero exit status

The downloaded source packages are in
    ‘C:\Users\byny\AppData\Local\Temp\Rtmp4WmSTV\downloaded_packages’

然后，

> library(rstan)
Error in library(rstan) : there is no package called ‘rstan’

RStan 安装失败。

我不知道如何解决这个问题。

更新:我卸载了 R 的所有版本并安装了最新版本的 64 位 R。然后我再次安装了 RStan。问题解决了。

Answer 1

我遇到了同样的问题。一切正常，直到 C++ 安装检查的“hello world”。然后，我运行了建议的行:

选项(repos = c(getOption(“repos”)，rstan =“http://wiki.rstan-repo.googlecode.com/git/”)) install.packages('rstan', type = 'source')

我有很多 404 错误。输出的最后几行是:

下载的源码包在 ‘C:\Users\U111499\AppData\Local\Temp\RtmpYfj24v\downloaded_pa​​ckages’

然后我转到 RStudio 的包选项卡，单击“安装包”，选择“安装自:包存档文件”，然后是我在上述路径下找到的“rstan_2.2.0.tar.gz”。这似乎终于奏效了。祝你好运!
