这是protagonist文件中的yarn.lock部分：
protagonist@^1.6.0:
version "1.6.5"
resolved "https://registry.yarnpkg.com/protagonist/-/protagonist-1.6.5.tgz#8275380368811ac6253b70bb1ac619e426bbfc$
dependencies:
nan "~2.2.1"
命令yarn install工作得很好，直到上周五。我检查了progragonist的repo，master分支的最新更新是在两个月前完成的。
我仍然是这项技术的菜鸟，所以我无法将错误输出解释为调试。欢迎任何帮助或建议。
也许这是因为你的系统缺少g ++编译器？
make：g ++：找不到命令
也许你可以尝试安装g++
yum install gcc-g++
干杯
