在 Raspberry Pi 上安装 Pillow 时出错

Question

我只是想在我的新 Raspberry Pi 上安装 yowsup。一切顺利，直到要安装 Pillow。我收到以下错误消息：

ValueError: --enable-jpeg requested but jpeg not found, aborting.

我用谷歌搜索了至少一个小时，但找不到正确答案。你对我有什么建议吗？

Answer 1

如果你查看 External Libraries section of the Pillow docs, you'll see that there are a number of libraries that should be present, including libjpeg and zlib. If you don't want JPEG support, you should download the "source" archive from PyPI，解压它，然后在结果目录运行 python setup.py install --disable-jpeg.

但是，我不推荐这样做，因为您将无法使用 Pillow 处理 JPEG。相反，使用 Pi 上的包管理器安装所有你想要支持的库，然后重新运行 pip install pillow.

Answer 2

看来您在尝试安装 PIL 时没有事先安装正确的软件包。尝试安装 libjpeg。

sudo apt-get install libjpeg-dev
