python - 无法安装reportlab mac OS X 10.9.2 + python2.7

Question

我正在努力使用 python 2.7 在 mac OS X 10.9.2 上安装 reportlab。我设法使用 pip3 安装它，即使我需要 python2.7，所以我相信我已经安装了所有必需的软件包。

你能帮忙吗？

这是安装日志(如果您需要完整的未剥离日志，请询问):

刚刚找到解决方案here 。只需在编译之前添加这些环境设置即可告诉 clang 忽略该错误。

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

希望能帮助别人!
