这就是我不使用依赖参数时会发生的事情

我是编程新手，并不确定如何阅读。当R发出同样的问题时，人们使用了其他一些包的命令，我尝试了它们，没有发生任何事情，所以我想在不知道我在做什么的情况下停止做任何事情。
答案 0 :(得分：1)
首先尝试：
install.packages("swirl", dependencies=TRUE)
如果失败，请尝试：
install.packages("stringr", dependencies=TRUE)
install.packages("stringi", dependencies=TRUE)
install.packages("swirl", dependencies=TRUE)
Swirl需要这些软件包，如果它们尚未使用dependencies=TRUE安装，则应强制它们同时安装，如果没有，请自行预安装并查看旋转是否有效。
