是否可以用pip显示反向依赖关系?

Is it possible to show the reverse dependencies with pip?

我想知道哪个软件包需要软件包foo.以及此软件包需要哪个版本的foo.

I want to know which package needs package foo. And which version of foo is needed by this package.

推荐答案

对于使用pip的python API已安装的软件包，这是可能的. pip.get_installed_distributions功能，可以为您提供当前安装的所有第三方软件包的列表.

This is possible for already installed packages using pip's python API. There is the pip.get_installed_distributions function, which can give you a list of all third party packages currently installed.

# rev_deps.py import pip import sys def find_reverse_deps(package_name): return [ pkg.project_name for pkg in pip.get_installed_distributions() if package_name in {req.project_name for req in pkg.requires()} ] if __name__ == '__main__': print find_reverse_deps(sys.argv[1])

此脚本将输出需要指定软件包的软件包列表:

This script will output the list of packages, that require a specified one:
