可以使用get_installed_distributions列出所有安装package。
import pip pip_version = pip.__version__ version = pip_version.split('.') major = int(version[0]) minor = int(version[1]) if major < 10 and minor == 0: # pip的版本早于10.0，get_installed_distributions就在pip中。 dists = pip.get_installed_distributions() elif major >= 21 and minor >= 2: # pip升级到21.2的版本后，get_installed_distributions已改成 # _get_installed_distributions，并且改到了pip-tools模块中。 from piptools.scripts.sync import _get_installed_distributions dists = _get_installed_distributions() else: # pip升级到10.0之后不能直接get_installed_distributions() from pip._internal.utils.misc import get_installed_distributions dists = get_installed_distributions() dists_list = sorted(["{:<25} {}".format(e.project_name, e.version) for e in dists]) for elem in dists_list: print(elem)摘自：
