即使PIP安装可以识别libffi，也无法找到ffi.h [英] PIP install unable to find ffi.h even though it recognizes libffi

问题描述

我已经在Linux服务器上安装了libffi，并且已将PKG_CONFIG_PATH环境变量正确设置为正确的目录，因为pip识别出已安装该变量；但是，在尝试安装pyOpenSSL时，pip指出找不到文件'ffi.h'.我知道ffi.h以及它的目录都存在，所以我该如何缩小ffi.h和pip之间的差距?

I have installed libffi on my Linux server as well as correctly set the PKG_CONFIG_PATH environment variable to the correct directory, as pip recognizes that it is installed; however, when trying to install pyOpenSSL, pip states that it cannot find file 'ffi.h'. I know both thatffi.h exists as well as its directory, so how do I go about closing this gap between ffi.h and pip?

推荐答案

您可以在pip命令(setup.py的同上)之前使用CFLAGS(以及LDFLAGS或其他各种编译器和链接器选项) ):

You can use CFLAGS (and LDFLAGS or various other compiler and linker options) in front of the pip command (ditto for setup.py):

类似于以下内容的方法应该起作用:

Something similar to the following should work:

CFLAGS=-I/usr/include/libffi/include pip install pyOpenSSL
