Python是一种流行的编程语言和框架，适用于现代操作系统（包括 macOS）上的应用程序。然而，Python通常分为两个不同的版本——Python 2 和Python 3。
Python 2曾经包含在 macOS 中，但出于安全原因不再支持。仅官方支持Python 3 。虽然您可以将其与Python 2一起安装在Mac上，但不建议将这两个版本安装在一起。
您可能根本不需要Python ，或者您可能只想安装最新版本。(Python)如果您不确定，最好了解如何在Mac上完全卸载(Mac)Python。要从Mac(Mac)中删除Python，请按照以下步骤操作。
识别Mac(Your Mac)上的Python 版本(Python Versions)
根据您的 macOS 版本，您可能安装了两个（或更多）版本的Python。这些通常分为Python 2和Python 3版本。Python 2默认包含在 macOS 中，直到它在Monterey 12.3及更高版本中被删除。
如果您要从Mac(Mac)中删除Python，您需要首先确定安装的是哪个版本。您可以按照以下步骤执行此操作。
使用终端
- 按Command + Space调出Spotlight 搜索(Spotlight Search)栏，打开Mac上的终端(Terminal)。
- 在Spotlight中，输入Terminal并按Enter。
- 在终端(Terminal)中输入并运行 python –version以查看Mac上安装的Python 2版本（如果有）。如果这不起作用，则说明尚未安装Python 2。
- 接下来，在终端(Terminal)中输入并运行 python3 –version来查看您的Mac上是否安装了Python 3，如果安装了，它是什么版本。
请记住，如果您有多个Python安装，这些命令将显示与当前路径配置关联的
Python安装的版本。
检查应用程序文件夹
您还可以在“应用程序”(Applications)文件夹中检查是否有任何手动Python安装。为此，请按照下列步骤操作。
- 在 Mac 上打开 Finder。
- 单击Finder中的“前往”菜单，然后从下拉菜单中选择“应用(Applications)程序”(Applications)，导航至“应用程序”文件夹。
- 查找任何与Python相关的应用程序文件夹，例如“ Python 3.x ”或“ Python 2.x ”，其中x表示特定版本号（例如Python 3.11）。
请记住(Remember)，各种Python版本可以在您的(Python)Mac计算机上共存，因此在尝试执行任何修改之前确定安装了哪些版本非常重要。
从 macOS
手动卸载Python
从Mac手动删除Python将需要您从两个不同位置删除文件。这包括框架文件（Python应用程序运行所需的核心文件）和Python可执行文件本身。
删除 Python 框架文件
要从Mac(Mac)手动卸载Python框架文件，请按照以下步骤操作。
- 打开Finder，按Go > Go to Folder，然后在弹出框中键入并选择 /Library/Frameworks/Python.framework。
- 如果您安装了多个版本的Python ，请在Versions子文件夹中确定要卸载的特定版本文件夹，例如Python 2或Python 3.xx 。
- 在继续删除之前，请确保您已备份使用此版本的Python开发的所有重要数据或项目。
- 接下来，打开终端应用程序。
- 在Terminal中，键入并运行以下命令以删除Python文件夹，将 /Path/To/ Python .framework 替换为您要删除的(Python)Python文件夹的实际路径，并特别小心不要键入错误的文件夹路径： sudo rm -rf /Path/To/Python.framework（例如 sudo rm -rf /Library/Frameworks/Python.framework/Versions/3.9/）。
- 系统可能会提示您输入管理员密码才能执行此命令。输入您的密码并确认删除以继续。
从/usr/local/bin Directory中删除Python
Python安装通常会将可执行文件添加到 /usr/local/bin 文件夹中。如果您已使用上述步骤删除了Python文件，则需要删除任何匹配的Python可执行文件或系统链接(syslinks)（其终端(Terminal)快捷方式），以避免以后出现兼容性问题。
- 要删除这些可执行文件，请打开Terminal ，并通过在(Terminal)Terminal中输入以下命令列出/usr/local/bin目录中所有与 Python 相关的文件： ls -l /usr/local/bin |grep '蟒蛇'
- 该命令将显示所有包含单词“python”的文件。' 确定(’ Identify)与您要卸载的
Python版本关联的文件。
- 要删除这些文件，请在Terminal(Terminal)中输入并运行以下命令，将 file_name 替换为要删除的文件的实际名称，并在执行命令之前格外小心： sudo rm -rf /usr/local/bin/file_name
此时，您选择的Python版本的所有相关文件都将被删除。重复(Repeat)这些步骤以删除与要卸载的特定版本关联的每个Python 相关文件。(Python-related)您还可以对要删除的
其他Python版本重复这些步骤。(Python)
使用 Homebrew 卸载 Python
Homebrew是一款流行的 macOS 第三方包管理工具，您可以从终端(Terminal)使用它。如果您想在不使用 App Store 的情况下
安装第三方 Mac 应用程序，您会经常使用它。(install third-party Mac applications)
如果您已使用Homebrew在Mac上安装了(Mac)Python，则可以按照以下步骤使用相同的工具轻松卸载它。
- 在 Mac 上打开终端应用程序。
- 在终端(Terminal)中，输入并运行brew list命令。这将列出您之前通过Homebrew(Homebrew)安装的所有已安装的软件包（例如，Python 3.11的 [email protected] ）。
- 要卸载这些Python软件包，请在(Python)终端(Terminal)中键入并运行brew uninstall python_package命令，将python_package替换为您在上一步中标识的适当的软件包名称（例如brew uninstall [email protected]）。
- 删除软件包后，输入并运行brew cleanup python_package以删除任何其他（现在是不必要的）文件，用正确的名称替换python_package（例如brew cleanup [email protected]）。
此时，您使用Homebrew安装的(Homebrew)Python版本已被删除。但是，如果您安装了多个版本，则接下来可能需要重复这些步骤才能删除这些版本。
在 Mac 上使用 Python
如果您需要在Mac上完全卸载Python，上述步骤将帮助您完成工作。也就是说，如果您想创建自己的应用程序，请不要害怕尝试 Python ，因为它是(give Python a try)最容易学习的编程语言(easiest programming languages to learn)之一。
扩展Python知识的一个好方法是尝试新的Python包。您可以通过安装 Python PIP(installing Python PIP)来完成此操作，这是一个包安装程序，可让您轻松安装和管理第三方模块。
但是，您需要熟悉使用终端(Terminal)应用程序。接下来您可以尝试一些重要的终端命令(important Terminal commands)来管理您的 macOS 系统。
How to Completely Uninstall Python on Your Mac
Python іs a popular prоgramming language and framework for applications on modern оperating systems (includіng macOS). However, Python is often split into two distinct versions—Python 2 and Python 3.
Python 2 used to be included in macOS, but it’s no longer supported for security reasons. Only Python 3 is officially supported. While you can install it on your Mac alongside Python 2, having the two versions installed together isn’t recommended.
You may not need Python at all, or you may just want the latest version installed. If you’re unsure, it’s a good idea to know how to completely uninstall Python on your Mac. To remove Python from your Mac, follow the steps below.
Identifying Python Versions on Your Mac
Depending on your version of macOS, you might have two (or more) versions of Python installed. These are usually split between versions of Python 2 and Python 3. Python 2 was included by default in macOS up until it was removed in Monterey 12.3 and later versions.
If you’re going to remove Python from your Mac, you need to identify which version is installed first. You can do this by following the steps below.
Using Terminal
- Open Terminal on your Mac by pressing Command + Space to bring up the Spotlight Search bar.
- In Spotlight, type Terminal and press Enter.
- Type and run python –version in the Terminal to see the Python 2 version installed on your Mac (if any). If this doesn’t work, there’s no Python 2 installed.
- Next, type and run python3 –version in the Terminal to see if Python 3 is installed on your Mac and, if so, what version it is.
Keep in mind that if you have multiple Python installations, these commands will display the version for the Python installation associated with the current path configuration.
Checking Applications Folder
You can also check for any manual Python installations in the Applications folder. To do this, follow these steps.
- Open Finder on your Mac.
- Navigate to the Applications folder by clicking on the Go menu in Finder and then selecting Applications from the drop-down menu.
- Look for any Python-related application folders, such as “Python 3.x” or “Python 2.x“, where x denotes a specific version number (eg. Python 3.11).
Remember that various Python versions can co-exist on your Mac computer, so it’s important to identify which versions are installed before attempting to perform any modifications.
Manually Uninstalling Python from macOS
Removing Python manually from your Mac will require you to remove files from two different locations. This includes the framework files (the core files needed for Python applications to run) and the Python executable files themselves.
Removing Python Framework Files
To manually uninstall Python framework files from your Mac, follow the steps below.
- Open Finder, press Go > Go to Folder, then type and select /Library/Frameworks/Python.framework in the pop-up box.
- If you have multiple versions of Python installed, identify the specific version folder you wish to uninstall, such as Python 2 or Python 3.x.x, in the Versions sub-folder.
- Before proceeding with deletion, make sure you’ve backed up any essential data or projects you may have developed using this version of Python.
- Next, open the Terminal app.
- In the Terminal, type and run the following command to remove the Python folder, replacing /Path/To/Python.framework with the actual path to the Python folder you wish to delete, and using extreme caution not to type in the wrong folder path: sudo rm -rf /Path/To/Python.framework (eg. sudo rm -rf /Library/Frameworks/Python.framework/Versions/3.9/).
- You might be prompted to enter your administrator password to execute this command. Enter your password and confirm the deletion to proceed.
Removing Python from the /usr/local/bin Directory
Python installation typically adds executables to the /usr/local/bin folder. If you’ve removed Python files using the steps above, you’ll need to remove any matching executables or syslinks for Python (the Terminal shortcuts to it) to avoid compatibility issues later.
- To remove these executables, open Terminal, and list all Python-related files in the /usr/local/bin directory by entering the following command in Terminal: ls -l /usr/local/bin | grep ‘python’
- This command will display all files that contain the word ‘python.’ Identify the files associated with the version of Python you wish to uninstall.
- To remove these files, enter and run the following command in Terminal, replacing file_name with the actual name of the file you want to delete and using extreme caution before executing the command: sudo rm -rf /usr/local/bin/file_name
At this point, all of the relevant files for your chosen Python version will be removed. Repeat these steps to remove each Python-related file associated with the specific version you’re uninstalling. You can also repeat these steps for other Python versions that you wish to remove.
Using Homebrew to Uninstall Python
Homebrew is a popular, third-party package management tool for macOS that you can use from the Terminal. You’ll often use it if you want to install third-party Mac applications without using the App Store.
If you’ve installed Python on your Mac using Homebrew, you can easily uninstall it using the same tool by following these steps.
- Open the Terminal app on your Mac.
- In the Terminal, type and run the brew list command. This will list any installed packages that you’ve previously installed via Homebrew (eg. [email protected] for Python 3.11).
- To uninstall these Python packages, type and run the brew uninstall python_package command in the Terminal, replacing python_package with the appropriate package name you identified in the previous step (eg. brew uninstall [email protected]).
- After removing the packages, type and run brew cleanup python_package to remove any additional (and now unnecessary) files, replacing python_package with the correct name (eg. brew cleanup [email protected]).
At this point, the version of Python that you installed using Homebrew has been removed. If you’ve installed multiple versions, however, you may need to repeat these steps to remove those versions next.
Using Python on your Mac
If you need to completely uninstall Python on your Mac, the steps above will help you get the job done. That said, don’t be afraid to give Python a try if you’re looking to create your own applications, as it’s one of the easiest programming languages to learn.
A good way to expand your Python knowledge is to try out new Python packages. You can do this by installing Python PIP, a package installer that allows you to easily install and manage third-party modules.
You’ll need to be comfortable using the Terminal app, however. You can try out some important Terminal commands to manage your macOS system next.
