我正在尝试mirt从源代码安装 R 包，但收到错误消息。我在 PC 和 Mac 上都收到错误消息。请注意，我的 PC 和 Mac 都设置为从源代码安装软件包，并且我已在两个系统上成功地从源代码安装软件包。例如，我已经验证我可以jsonlite使用以下命令在我的 PC 和 Mac 上成功地从源代码安装包：install.packages("jsonlite", type = "source"). 我的 PC 上安装了Rtools 4.0 ，Mac 上安装了Xcode 和R 编译器工具。该软件包的创建者 Phil Chalmersmirt建议我的编译器可能需要重新配置（因为看起来 g++.exe 不在 R 可以看到的路径中）。我该如何解决这个问题，以便我可以mirt从源代码安装包？

这是我在我的 PC 上尝试从源代码安装时收到的错误：

验证 Rtools 4.0 已安装：

> Sys.which("make")
                              make 
"C:\\rtools40\\usr\\bin\\make.exe"

但是，R 似乎不知道在哪里g++.exe：

我最终能够弄清楚这一点。出现此问题是因为我的Rprofile.site文件将文本打印到控制台：

.First <- function(){
  cat("\nWelcome at", date(), "\n")
}

.Last <- function(){
  cat("\nGoodbye at ", date(), "\n")
}

问题在于，正如这里所指出的，“这台机器上的cat输出似乎.Rprofile被插入到g++命令中。删除cat调用后，库安装没有错误。”

注释掉文件中的cat调用后RProfile.site，我能够从源代码成功安装包。
