我正在使用Python3.6开发Oracle VirtualBox Fedora 64位VM。我已经配置了一个venv来安装apache-airflow。我的pip3已更新为18.0，并且我已经用yum安装了许多开发工具：
$ yum groupinstall "Development tools"
$ yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel python3-devel.x86_64 cyrus-sasl-devel.x86_64
$ yum install python3-psutil.x86_64
$ yum install libevent-devel
即使使用这些开发工具，每当我尝试运行pip安装时，都会出现gcc错误：
$ pip3 install apache-airflow
错误及其之前的终端输出如下：

cc1: error: ‘-fcf-protection=full’ requires Intel CET support. Use -mcet or both of -mibt and -mshstk options to enable CET

似乎psutil或gcc出现错误，这就是为什么我为psutil运行yum安装，但没有解决任何问题。
$ yum install python3-psutil.x86_64
我在其他地方找到的最有用的信息是有关annobin和gcc 8.1.1之间的版本不匹配。但是，我拥有的annobin版本似乎是补丁版本。
关于'-fcf-protection = full'错误，我没有在网上找到任何内容。我不确定这将如何影响气流，也不确定如何解决“ cc1：错误”。
任何帮助或指导将不胜感激。

我遇到了同样的问题，但得到了解决 在安装Apache Airflow之前，请安装
sudo yum -y install gcc gcc-c++

您正在安装到虚拟环境中，但是用于构建psutil的工具链在那里不起作用。另外，将预构建的psutil与yum install python3-psutil.x86_64一起安装不会对您的虚拟环境有任何影响。
您需要在安装到venv的psutil的系统软件包中进行符号链接，大致与：ln -s /usr/lib/python3.6/dist-packages/psutil* $VIRTUAL_ENV/lib/python*/site-packages

我可以通过dnf update annobin -y更新annobin，bugzilla上有一个相关线程
