我试过这个答案也失败了,Getting gcc failed error while installing scrapy,有人能告诉我如何纠正吗?

PS:我的操作系统是centos 6.5

【问题讨论】:

你试过关注cryptography.io/en/latest/installation/…吗? 您是否尝试过阅读实际出现的故障? 我还不明白那些失败,所以我在这里发布。 我还不明白这些失败,所以我将它添加到我的问题中。希望你能告诉我更多的建议,谢谢。 当我 pip install cryptography distutils.errors.DistutilsError: Setup script exited with error: command 'gcc' failed with exit status 1 时它也失败了 【参考方案1】:

你的问题是:

c/_cffi_backend.c:14:17: error: ffi.h: No such file or directory

您需要安装 libffi-devel 软件包(在 Debian/Ubuntu 上为 libffi-dev)。
