Using pip, is it possible to figure out which version of a package is currently installed?

我知道 pip install XYZ --upgrade 但我想知道是否有类似 pip info XYZ 的东西.如果不是，最好的方法是告诉我当前使用的是哪个版本.

I know about pip install XYZ --upgrade but I am wondering if there is anything like pip info XYZ. If not what would be the best way to tell what version I am currently using.

推荐答案

As of pip 1.3，有一个 pip show 命令.

As of pip 1.3, there is a pip show command.

$ pip show Jinja2
---
Name: Jinja2
Version: 2.7.3
Location: /path/to/virtualenv/lib/python2.7/site-packages
Requires: markupsafe

在旧版本中，pip freeze 和 grep 应该可以很好地完成这项工作.

$ pip freeze | grep Jinja2
Jinja2==2.7.3
