尝试在 Mac 上升级 Pillow 时出错

Question

我正在尝试在我的 Mac 上升级 Pillow。当我运行sudo pip install Pillow 时，我得到了

Requirement already satisfied (use --upgrade to upgrade): Pillow in ./lib/python2.7/site-packages/Pillow-2.3.0-py2.7-macosx-10.8-intel.egg

我运行 sudo pip install --upgrade Pillow 并收到以下错误：

有谁知道如何解决这个问题？谢谢。

这对我有用：

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install --upgrade pillow
