gcc 版本：

$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/c++/4.2.1
Apple LLVM version 10.0.1 (clang-1001.0.46.4)
Target: x86_64-apple-darwin18.7.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

蟒蛇版本：

$ python3 --version
Python 3.6.7

（旁注，pythonandpython3指向同一个 python，pipandpip3指向同一个（对应的）pip。）

我也尝试运行xcode-select --install，但这告诉我'命令行工具已经安装，使用“软件更新”安装更新'（Xcode 是最新的）。

解决方案

跑

export MACOSX_DEPLOYMENT_TARGET=10.9

在运行之前pip install python-igraph。然后你应该看到它安装成功：

$ pip install python-igraph
