pip配置和安装模块问题

Question

系统环境

• centos 7.2

• pytohn 2.7.5

pip配置信息

输入pip list，提示：

DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.

然后我在/root/.pip/pip.conf写入:

[list]
list_format=columns

还是有上面的那句警告。怎么解？

安装ansible

使用pip方式安装ansible

pip install ansible

安装不成功，一直报错

Command "/usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-AClS41/cryptography/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-DsXkPd-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-AClS41/cryptography/

前文是

这个怎么破？

Answer 1

第一个问题

人家说了是

[list]
format=columns

第二个

没有python的头文件，也就是说没有安装python的开发库

sudo yum install python-dev python3-dev

Answer 2

安装ansible要解决依赖的

yum install gcc libffi-devel python-devel openssl-devel -y
pip install cryptography

Answer 3

建議使用 epel 上的 yum 來源安裝 Ansible。
