尝试安装tidyverse包时，我在安装依赖项tidyr时遇到错误。
以下是我收到的消息尾部：
cpp11.cpp:31:100: error: ‘unmove’ is not a member of ‘cpp11’
return cpp11::as_sexp(simplifyPieces(cpp11::unmove(cpp11::as_cpp<cpp11::list>(pieces)), cpp11::unmove(cpp11::as_cpp<int>(p)), cpp11::unmove(cpp11::as_cpp<bool>(fillLeft))));
^~~~~~

以我幼稚的眼光看，似乎问题出在cpp11上。我看到一个类似的问题，涉及到tidyr安装错误，原因是由于cpp11编译错误（R tidyr package installation failed due to cpp11 compilation error (expansion pattern x contains no argument packs)），但该问题是针对RHEL系统的。
我在我的系统上安装了最新版本的gcc/c++（4:7.4.0-1ubuntu2.3）。最新版本的系统依赖项libcurl4-openssl-dev libssl-dev libxml2-dev也已安装。
