安装程序
¶
Added in version 3.4.
源代码： Lib/ensurepip
The
ensurepip
package provides support for bootstrapping the
pip
installer into an existing Python installation or virtual environment. This bootstrapping approach reflects the fact that
pip
is an independent project with its own release cycle, and the latest available stable version is bundled with maintenance and feature releases of the CPython reference interpreter.
In most cases, end users of Python shouldn’t need to invoke this module directly (as
pip
should be bootstrapped by default), but it may be needed if installing
pip
was skipped when installing Python (or when creating a virtual environment) or after explicitly uninstalling
pip
.
注意
This module
does not
access the internet. All of the components needed to bootstrap
pip
are included as internal parts of the package.
