Ansible即使说成功也没有升级

我在2.8.4上运行了以下程序来升级Ansible：

s-MacBook-Pro:~ albertski$ sudo pip install ansible --upgrade
Password:
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date.

试图降级到2.7.13，我遇到了同样的问题：

sudo pip install ansible==2.7.13

操作系统：OSX Mojave

您正在使用python2 pip安装Ansible，而您的shell路径中的Ansible似乎正在使用python3

请尝试以下操作： sudo pip3安装ansible-升级

或者更好的是，将其保存在用户homedir中

pip3安装-用户ansible-升级

我在/usr/local/bin中查看了：-rwxr-xr-x 1 root admin 215 Sep 10 17:31 pip-rwxr-xr-x 1 root admin 215 Sep 10 17:31 pip2.7 lrwxr-x 1 root admin 2018年11月29日pip3->../../../Library/Frameworks/Python.framework/Versions/3.7/bin/pip3-lrwxr-x 1 root admin 68 2018年11月29日pip3.7->../../Library/Frameworks/Python.framework/Versions/3.7/bin/pip3.7当我在../../../Library/Frameworks/Python.framework/Versions/3.7/bin/pip3.7里面看不到pip3。仅供参考，我在Mac Mojaven上，在我的.bashprofile路径=/Library/Frameworks/Python.framework/Versions/3.7/bin中注意以下内容：${PATH}。这可能是导致问题的原因吗？

sudo pip install ansible==2.7.13
