安装compi后重新安装SQLAlchemy并加速

Question

我试图用pip3 install sqlalchemy安装sqlalchemy，但是我没有安装clang，所以它警告说“没有启用加速”。如何在OS X Yosemite上获得clang，然后如何重新安装sqlalchemy？你知道吗

command '/usr/bin/clang' failed with exit status 1
WARNING: The C extension could not be compiled, speedups are not enabled.
Failure information, if any, is above.
Retrying the build without the C extension now.
WARNING: The C extension could not be compiled, speedups are not enabled.
Plain-Python build succeeded.

要获得clang，您需要从appstore安装XCode。你知道吗

之后，可以使用pip install upgrade force-reinstall SQLAlchemy重新安装SQLAlchemy
