在 Windows 10 Education 64 位上，我在 RStudio 版本 1.2.1335 中运行 R 版本 3.6.0 和 Rtools 3.5.0。当我尝试安装时收到以下错误devtools::install_github("RcppCore/Rcpp")

要重现此代码：

>install.packages("devtools")
>library("devtools")
>options(buildtools.check = NULL)
>install.packages("Rcpp", dep = TRUE)
>devtools::install_github("RcppCore/Rcpp")

我的系统路径是这样开始的：

>Sys.getenv()['PATH']
PATH                           
        C:\Program 
Files\R\R-3.6.0\bin\x64;C:\Rtools\bin;C:\Rtools\mingw_32\bin;C:\Rtools\mingw_64\bin;

Program 和 Files 之间有一个空格

作为管理员，我将Makeconf32 位和 64 位文件夹中的通过记事本更改为：BINPREF ?= D:/Rtools/mingw_32/bin/和 BINPREF ?= D:/Rtools/mingw_64/bin/

我试过这个链接来修复 Makeconf 文件： Rcpp Rtools installed but error message g++ not found

对于 Rcpp 编译问题，此链接似乎很有帮助： Cannot compile from source with Rcpp on Windows 7

这是否与注释掉 rpp 标签或更改 Makevars 或 Makeconf 中的某些变量有关？如果不是，为什么代码devtools::install_github("RcppCore/Rcpp")会在错误的 bin 中查找 g++？它在里面寻找它

C:/Rtools/bin/g++

如你看到的。

将 g++.exe 复制并粘贴到 > C:/Rtools/bin/g++ 后，我收到另一个错误：

我不认为复制 g++.exe 是正确的方法。但是，值得一试，并且可能会导致正确的答案。请帮忙。（如果您devtools::install_github("RcppCore/Rcpp")连续运行，您需要删除 ~/R/win-library/3.6 中的锁定文件夹（00LOCK-Rcpp）以避免ERROR: failed to lock directory）谢谢！
