错误处理：由于环境错误，无法安装包：[Errno 1] 操作不允许

解决安装Ansible时出现的错误备忘录

$ sudo pip3 install ansible
...
Collecting MarkupSafe>=0.23 (from jinja2->ansible)
Collecting pycparser (from cffi!=1.11.3,>=1.7->cryptography->ansible)
Installing collected packages: pycparser, cffi, six, idna, asn1crypto, cryptography, bcrypt, pynacl, pyasn1, paramiko, PyYAML, MarkupSafe, jinja2, ansible
Could not install packages due to an EnvironmentError: [Errno 1] Operation not permitted: '/bin/ansible-console'

似乎在/bin目录下，即使使用sudo也无法放置文件。
因此，我们可以通过在pip命令中加入–user选项来更改安装位置。

pip3 install ansible --user

我的Mac环境安装在/Users/paper2/Library/Python/3.7/bin上，因此设置了路径并成功安装。

顺便提一下，确认密码的方法如下所示：

$ pip3 show ansible
