大家好，

我正在学习 Lua。从一个 Readme 文档上得知，我需要通过 Luarocks 安装"display"，然而遇到了问题。当我输入"luarocks install display"时，

    Installing https://raw.githubusercontent.com/torch/rocks/master/display-scm-0.rockspec...
    Using https://raw.githubusercontent.com/torch/rocks/master/display-scm-0.rockspec... switching to 'build' mode

    Missing dependencies for display:
    async >= 1.0
    luasocket >= 2.0

目前为止我已经搜索了很多但还没有找到相关解决方案，我认为问题存在于"async"的安装中，但是我不知道如何修复。非常感谢您的帮助！

最好的祝愿， Marvin

我使用以下命令将我的 gcc 版本降级解决了问题：

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-5 g++-5
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 60 --slave /usr/bin/g++ g++ /usr/bin/g++-5

希望这可以帮到您。

将一个名为 cc 的文件添加到你的 PATH 中某个目录下，并包含以下内容，并在该文件上运行 chmod +x cc：

/usr/bin/"${0##*/}" "$@" -Wno-implicit-fallthrough
