c++ - 由于 cpp11 编译错误，R tidyr 包安装失败（扩展模式 x 不包含参数包）

问题描述

我有以下与 cp11 相关的错误。看起来 cp11 编译有错误，我不知道如何解决。

我试图做的是卸载软件包并重新安装它。

我在 RHEL 7 上，gcc 版本是 4.8.5

解决方案

如@Maurits Evers 所述，较新版本的 gcc 将正确编译 tidyr。

#Enable the rhscl repository
yum-config-manager --enable rhel-server-rhscl-7-rpms

#Install devtooset-X
yum install devtoolset-X

#Open a shell with the required environment variables.
scl enable devtoolset-X bash

之后打开一个 R shell。如果在非交互式脚本中使用，请获取 scl enable 文件，该文件将在当前 shell 中设置环境变量，

 source /opt/rh/devtoolset-X/enable
