非官方的、可导入的api管道
pip-api的Python项目详细描述
由于^{
然而，这并不意味着人们没有尝试import pip，通常
当pip的维护人员进行例行重构时，最终会很头疼。
这个项目试图提供一个可导入的pipapi，它完全是。
使用程序中推荐的pip方法遵从。
支持的命令
并非所有版本的pip和所有平台都支持所有命令。
如果您尝试使用的命令不兼容，pip_api将引发
pip_api.exceptions.Incompatible程序要捕获的异常。
所有版本均可用：
pip_api.version()Returns the
pipversion as a string, e.g."9.0.1"pip_api.installed_distributions()Returns a list of all installed distributions as a
Distributionobject with the following attributes:Distribution.name(string): The name of the installed distributionDistribution.version(packaging.version.Version): The version of the installed distributionDistribution.location(string): The location of the installed distributionDistribution.editable(bool): Whether the distribution is editable or not
pip_api.parse_requirements(filename, options=None, include_invalid=False)Takes a path to a filename of a Requirements file. Returns a mapping from package name to a
packaging.requirements.Requirementobject with the following attributes:Requirement.name(string): The name of the requirement.Requirement.extras(set): A set of extras that the requirement specifies.Requirement.specifier(packaging.specifiers.SpecifierSet): ASpecifierSetof the version specified by the requirement.Requirement.marker(packaging.markers.Marker): AMarkerof the marker for the requirement. Can be None.Optionally takes anoptionsparameter to override the regex used to skip requirements lines. Optionally takes aninclude_invalidparameter to return anUnparsedRequirement` in the event that a requirement cannot be parsed correctly.

一起提供
pip_api.hash(filename, algorithm='sha256')Returns the resulting as a string. Valid
