为什么'pip show'或'pip list'不适合我？

Question

Python pip正在为我安装和更新软件包,但似乎不支持一些记录的命令(至少在OS 10.8.2和Python 2.7.2上运行1.2.1).当我尝试

pip list

要么

pip show <pkgname>

我明白了

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

这些命令是否尚未实施(尽管已记录在案)？

Answer 1

你正在寻找的新功能是最新的 - 它们在1.2.1.post1中,但不在1.2.1中,而你可能正在查看的文档(http://www.pip-installer. org/en/latest /)目前为1.2.1.post1.

localhost-2:~ $ pip --version
pip 1.2.1.post1 from /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip-1.2.1.post1-py2.7.egg (python 2.7)
localhost-2:~ $ pip --help
Usage: pip COMMAND [OPTIONS]

Commands:
  bundle               Create pybundles (archives containing multiple packages)
  freeze               Output all currently installed packages (exact versions) to stdout
  help                 Show available commands
  install              Install packages
  list                 List installed packages (including editables).
  search               Search PyPI
  show                 Output installed distributions (exact versions, files) to stdout
  uninstall            Uninstall packages
  unzip                Unzip individual packages
  zip                  Zip individual packages

如果您需要它们,您可以获得开发版本:
