第三方库存储在 Python 的虚拟环境中,默认位置为:Windows:%APPDATA%\Python\<Python version>\Lib\site-packagesUnix:/usr/local/lib/python\<Python version>/site-packages

Where are the libraries downloaded by python stored?

Python 下载库的存储位置

要确定 Python 下载的库的存储位置,我们需要了解 Python 的包管理系统。

pip 和 venv

Python 使用 pip 程序包管理器来下载和安装第三方库。当您使用 pip 安装库时,它将被存储在 Python 的虚拟环境中。

虚拟环境是 Python 解释器的隔离副本,允许您为不同的项目安装不同的库版本,而不会影响其他项目。

默认情况下, pip 将库安装到用户的虚拟环境中。在 Windows 系统上,通常位于以下位置:

<code>%APPDATA%\Python\<Python version>\Lib\site-packages</code>
Copy after login

在 Unix 系统上,通常位于以下位置:

<code>/usr/local/lib/python\<Python version>/site-packages</code>
Copy after login

确定确切位置

您可以使用以下命令确定特定库的安装位置:

<code>pip show <library name></code>
Copy after login

这将打印有关库的信息,包括其安装位置:

<code>Location: <path to library></code>
Copy after login

其他存储位置

在某些情况下,库可能不会安装到虚拟环境中。例如,您可能已使用 sudo 命令通过系统包管理器安装了库。在这种情况下,库将安装到系统范围的库目录中,例如:

  • Windows: C:\Python\\Lib\site-packages
  • Unix: /usr/lib/python\/site-packages

如果您不确定库安装在哪里,您可以使用以下命令搜索文件系统:

<code>find / -name <library name></code>
Copy after login

这将找到系统的任何匹配文件。
