r - stringr 不会安装在 R 中

Question

我在安装 stringr 时遇到问题。这是我请求安装 stringr 时得到的结果:

utils:::menuInstallPkgs()
also installing the dependency ‘stringi’

There are binary versions available but the source versions are later:

        binary source needs_compilation

stringi  1.1.5  1.1.6              TRUE

stringr  1.2.0  1.3.0             FALSE

Binaries will be installed

R 社区一般doesn't support old versions . 3.2 系列的最后一个版本大约是两年前发布的。建议更新到最新的稳定版本。
