关于python：为什么’pip show’或’pip list’不适合我？

Why don't 'pip show' or 'pip list' work for me?

python的pip正在为我安装和更新软件包而工作，但是一些文档化的命令似乎不受支持(至少在OS 10.8.2和python 2.7.2上运行1.2.1)。当我尝试

pip list

或

1	pip show <pkgname>

我得到

Usage: pip COMMAND [OPTIONS]
No command by the name pip <cmd>
(maybe you meant"pip install <cmd>")

这些命令是否尚未执行(尽管已记录在案)？

您正在寻找的新功能是非常新的——它们位于1.2.1.post1中，但不在1.2.1中，您可能正在寻找的文档(http://www.pip-installer.org/en/latest/)当前位于1.2.1.post1中。
