推荐答案

如我所见，在

as I can see there is no "memoise_0.1.zip" at http://cran.rstudio.com/bin/windows/contrib/3.0/ . However, there is the "memoise_0.2.1.zip" file.

您正在使用哪个版本的RStudio IDE?您已经安装了备忘录吗?也许您应该尝试更新备忘录包.

What version of RStudio IDE are you using? Do you have memoise already installed? Maybe you should try to update the memoise package.
