Pythonpip正在帮助我安装和更新软件包，但似乎不支持某些记录在案的命令（至少在 OS 10.8.2 和 Python 2.7.2 上运行 1.2.1 时）。当我尝试

pip list

或者

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）？

您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，而且您可能正在查看的文档 (http://www.pip-installer. org/en/latest/) 目前适用于 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

如果你想要它们，你可以得到开发版本：

git clone https://github.com/pypa/pip.git

从 pip 1.1 开始，可用的命令是：

  • bundle：创建 pybundles（包含多个包的存档）
  • freeze：将所有当前安装的包（确切版本）输出到标准输出
  • help: 显示可用命令
  • install：安装包
  • 搜索：搜索 PyPI
  • 卸载：卸载软件包
  • unzip：解压单个包
  • zip：压缩单个包

有关已安装软件包的列表，请尝试yolk。

作为一种解决方法，您可以使用pip freeze.

从帮助提示：

freeze: Output all currently installed packages (exact versions) to stdout
