【问题描述】：

我正在尝试安装 fblualib，但遇到了我无法找到解决方法的问题。

我发出了以下命令：

git clone https://github.com/facebook/fblualib.git
cd fblualib/fblualib/python
luarocks make rockspec/*

并有以下输出：非常感谢任何帮助，因为我真的陷入了这个错误。

        cmake -E make_directory build &&
        cd build &&
        cmake -DROCKS_PREFIX=/home/ubuntu/usr/local/torch/install/lib/luarocks/rocks/fbpython/0.1-1 \
              -DROCKS_LUADIR=/home/ubuntu/usr/local/torch/install/lib/luarocks/rocks/fbpython/0.1-1/lua \
              -DROCKS_LIBDIR=/home/ubuntu/usr/local/torch/install/lib/luarocks/rocks/fbpython/0.1-1/lib \
              .. &&
        make

所以基本上我发现了这个问题，通过在 python 编译期间添加--enable-shared 解决了所有问题。所以我再次重新编译了python并且它工作了。希望它可以帮助其他人并防止他们花费相同的时间。
