官网安装 emsdk 的方法比较慢，可以直接安装 emscripten brew install emscripten.
安装完底部有提示需要修改手动修改 ~/.emscripten.
将

LLVM_ROOT = os.path.expanduser(os.getenv('LLVM') or '/usr/bin') # directory
BINARYEN_ROOT = os.path.expanduser(os.getenv('BINARYEN') or '') # directory

修改成

LLVM_ROOT = os.path.expanduser(os.getenv('LLVM') or '/usr/local/opt/emscripten/libexec/llvm/bin') # directory
#BINARYEN_ROOT = os.path.expanduser(os.getenv('BINARYEN') or '') # directory

再运行 emcc -v

在编译过程中，如 emcc hello.c -s WASM=1 -o hello.html，可能会报 OSError: [Errno 2] No such file or directory 的错误，安装 brew install cmake 搞定！
