It depends on the operating system.
这取决于操作系统。
With pip 20.1or later, you can find it with:
使用pip 20.1或更高版本，您可以通过以下方式找到它：

For example with macOS:
以 macOS 为例：

You can backup the associated wheelrather than attempting to perform a backup of the cache folder.
您可以备份关联的轮子，而不是尝试执行缓存文件夹的备份。
Download the wheel for csselect of version 0.9.1 into /tmp/wheelhouse:
将 0.9.1 版 csselect 的轮子下载到/tmp/wheelhouse：
pip wheel --wheel-dir=/tmp/wheelhouse cssselect==0.9.1
Install the downloaded wheel:
安装下载的轮子：
pip install /tmp/wheelhouse/cssselect-0.9.1-py2-none-any.whl

The default location for the cache directory depends on the Operating System:
Unix
~/.cache/pip and it respects the XDG_CACHE_HOME directory.
macOS
~/Library/Caches/pip
Windows
<CSIDL_LOCAL_APPDATA>\pip\Cache
Wheel Cache
pip will read from the subdirectory wheels within the pip cache directory and use any packages found there. [snip]
https://pip.pypa.io/en/latest/reference/pip_install/#caching
缓存目录的默认位置取决于操作系统：
Unix
~/.cache/pip 并且它尊重 XDG_CACHE_HOME 目录。
苹果系统
〜/图书馆/缓存/点
视窗
<CSIDL_LOCAL_APPDATA>\pip\Cache
轮缓存
pip 将从 pip 缓存目录中的子目录轮子中读取并使用在那里找到的任何包。[剪辑]

The location of the cache directory can be changed via the command line option --cache-dir.
可以通过命令行选项更改缓存目录的位置--cache-dir。

Pythonic and cross-platform way:
Pythonic 和跨平台方式：
import pip
from distutils.version import LooseVersion
if LooseVersion(pip.__version__) < LooseVersion('10'):
# older pip version
from pip.utils.appdirs import user_cache_dir
else:
# newer pip version
from pip._internal.utils.appdirs import user_cache_dir
print(user_cache_dir('pip'))
print(user_cache_dir('wheel'))
Under the hood, it normalizes paths, manages different locations for exotic and ordinary operating systems and platforms, performs Windows registry lookup.
在幕后，它规范化路径，管理异国和普通操作系统和平台的不同位置，执行 Windows 注册表查找。
It may worth mentioning, if you have different Python versions installed, 2.x'es and 3.x'es, they all do share the same cache location.
值得一提的是，如果您安装了不同的 Python 版本，2.x'es 和 3.x'es，它们都共享相同的缓存位置。
