Ansible psutil无法在python3 virtualenv内部进行pip安装：致命错误：Python.h:没有这样的文件或目录

我创建了一个python3virtualenv，以便在Python3中运行塔作业，因为python2是EOL。我按照此处的说明进行了操作：但psutil安装失败，出现以下错误：

python36/root/usr/include/python3.6m -c psutil/_psutil_common.c -o build/temp.linux-x86_64-3.6/psutil/_psutil_common.o
    psutil/_psutil_common.c:9:20: fatal error: Python.h: No such file or directory
     #include <Python.h>
                        ^
    compilation terminated.
    error: command 'gcc' failed with exit status 1

其他人建议安装python3-devel，但已经安装了

环境：

• CentOS 7.7
• 蟒蛇3-devel-3.6.8
• Python 3.6.8
• pip3 9.0.3
• Ansible塔3.5.0

事实证明virtualenv命令是一个python2构造。Ansible Tower文档的建议是错误的：

改用Python3 venv模块：

sudo python3 -m venv /opt/my-envs/custom-venv
source /opt/my-envs/custom-venv/bin/activate 
sudo /opt/my-envs/custom-venv/bin/pip install psutil

这对我有用

yum install python3-devel

sudo python3 -m venv /opt/my-envs/custom-venv
source /opt/my-envs/custom-venv/bin/activate 
sudo /opt/my-envs/custom-venv/bin/pip install psutil

yum install python3-devel
