错误:PIP安装pycapnp

Question

我一直在尝试在MacBook Pro上通过PIP安装Pycapnp。但是我似乎正在尝试下载它的问题。

以下是错误：

尝试通过声明

来安装它

➜ export MACOSX_DEPLOYMENT_TARGET=10.10

或

➜ CFLAGS='-stdlib=libc++' pip install pycapnp

或

➜ export CXXFLAGS="-stdlib=libc++"
➜ export CFLAGS="-stdlib=libc++"

顺便说一句，我在MacBook上的Virtualenv中成功安装了它。
