【问题描述】：
我是 R 和任何类型编程的完全初学者，并且正在努力安装 LTM 包以在 SPSS 26 中进行 rasch 分析。
我用过命令
install.packages("ltm")
在 R3.3、3.5 和 3.6（都在 MS windows 中）尝试过，因为它们与我可以访问的 SPSS 版本兼容，并返回以下输出：
*Installing package into ‘C:/Users/info/OneDrive/Documents/R/win-library/3.5’ (as ‘lib’ is unspecified) also installing the dependencies ‘admisc’, ‘polycor’ There are binary versions available but the source versions are later:

我还尝试安装早期版本的 admisc 和 polycor，但收到一条错误消息，指出此版本的 R 无法使用它们。
希望有人能发现我在这里做错了什么！
提前致谢

听起来你需要安装rtools，它可以让你从源代码构建包。

@AllanCameron 是正确的。此外，当被询问时，您可以选择二进制版本而不是源版本。二进制版本是预编译的，而源版本（通常是较新的）需要编译和附加软件，因此需要使用 rtools。
