用于查询系统上安装的pypi和python包的命令行工具。
yolk的Python项目详细描述
Installation
您可以使用pip install yolk或通过发行版的包管理器（如果可用）安装yolk。
从0.0.7开始，yolk作为dev python/yolk和一个名为dev python/yolk portage的移植插件出现在gentoo的移植树中。portage插件显示哪些python包是通过portage安装的，哪些是直接用pip（或easy_install）安装的。看看那个插件，为你最喜欢的发行版做一个。这是一个很好的方法找到Python克鲁夫特。
Summary
yolk是一个python工具，用于获取有关已安装的python包的信息，并在pypi（python包索引）上查询可用的包。
您可以通过查询pypi来查看哪些包是活动的、非活动的或处于开发模式中的，并显示哪些包具有较新的可用版本。
用法示例：
$ yolk -l
List all installed Python packages
$ yolk -a
List only the activated packages installed (Activated packages are normal packages on sys.path you can import)
$ yolk -n
List only the non-activated (--multi-version) packages installed
$ yolk -l -f License,Author nose==1.0
Show the license and author for version 1.0 of the package `nose`
$ yolk --entry-map nose
Show entry map for the nose package
$ yolk --entry-points nose.plugins
Show all setuptools entry points for nose.plugins
这些选项查询pypi:
$ yolk -U pkg_name
Shows if an update for pkg_name is available by querying PyPI
$ yolk -U
Checks PyPI to see if any installed Python packages have updates available.
$ yolk -F Paste
Download source tarball for latest version of Paste to your current directory
$ yolk -F Paste -T svn
Do a subversion checkout for Paste to a directory named Paste_svn in your current directory.
$ yolk -L 2
Show list of CheeseShop releases in the last two hours
$ yolk -C 2
Show detailed list of changes in the CheeseShop in the last two hours
$ yolk -M Paste==1.0
Show all the metadata for Paste version 1.0
$ yolk -M Paste
Show all the metadata for the latest version of Paste listed on PyPi
$ yolk -D cheesecake
Show all (source, egg, svn) URL's for the latest version of cheesecake packages
$ yolk -T source -D cheesecake
Show only source code releases for cheesecake
$ yolk -H twisted
Launches your web browser at Twisted's home page
Tips and Tricks
- Use yolk inside your virtualenv to see which packages are installed.
- Upgrade all installed Python packages:
Warning: You only want to do this inside a virtualenv. If you’re using Linux, use your package manager to install Python packages globally whenever possible. Think twice before upgrading all packages system-wide on OSX.
$ pip install -U yolk -U | awk ‘{print $1}’
