pip 安装 python-lzo 时找不到文件错误

Question

python-lzo我正在尝试在 mac OS Sierra 上安装。我曾经brew安装过clzo库：

brew update
brew install lzo

然后我尝试python-lzo使用虚拟环境进行安装pip：

$ virtualenv ./env
$ . ./env/bin/activate
$ pip install python-lzo

这给了我以下输出：

    ----------------------------------------

该lzo1x.h文件确实存在于此处：/usr/local/opt/lzo/include/lzo/或使用brew命令：

$ ls $(brew --prefix lzo)/include/lzo/

然后我尝试设置CFLAGS环境变量，但仍然有相同的错误：

$ export EXTRA_CFLAGS=-I/usr/local/opt/lzo/include && export EXTRA_CXXFLAGS=-I/usr/local/opt/lzo/include && export EXTRA_LDFLAGS=-L/usr/local/opt/lzo/lib && pip install

并在绝望中：

$ export EXTRA_CFLAGS=-I/usr/local/opt/lzo/include/lzo && export EXTRA_CXXFLAGS=-I/usr/local/opt/lzo/include/lzo && export EXTRA_LDFLAGS=-L/usr/local/opt/lzo/lib && pip install python-lzo

还是一样的错误信息，有什么想法吗？

-- 更新了 --
还尝试将变量直接传递到pip：

pip install --global-option='build_ext' --global-option='-I/usr/local/opt' --global-option='-I/usr/local/opt/lzo/include/lzo' --global-option='-L/usr/local/opt/lzo/lib' python-lzo

这次我得到了一个稍微不同的错误：

非常感谢

- 成功 - -

非常感谢@daphtdazz，您的解决方案（见下文）有效！我稍微修改了一下，使用brew --cellar命令来获取文件的位置lzo：

export C_INCLUDE_PATH=$(brew --cellar lzo)/2.09/include/lzo:$(brew --cellar lzo)/2.09/include/ export LIBRARY_PATH=/usr/local/lib pip install python-lzo

Answer 1

我得到了和你一样的结果，最终这对我有用：

export C_INCLUDE_PATH=/usr/local/Cellar/lzo/2.09/include/lzo:/usr/local/Cellar/lzo/2.09/include 
export LIBRARY_PATH=/usr/local/lib 
pip install python-lzo

（显然，您可能需要根据lzo您安装的brew发行版本来调整这些。）

这回答了我的问题，但我真的不明白为什么这些配置不正确......

我也安装了 Xcode 开发工具，我认为它们与brew之前有冲突pip，所以也许就是这样。我会继续看看，如果我解决了，我会更新这个答案。

编辑

看看这个setup.py文件，python-lzo似乎有一些奇怪的事情发生，特别是我担心在 Windows 上都添加了包含路径，这表明lzo源代码分发没有很好地安排。但似乎没有一种设计方法可以通过brew安装在macOS上实现这一点，所以我认为它的包含部分至少最好通过额外的环境变量来解决。
