Python3安装turtle全教程

说明

最近需要使用Python2中的turtle画图，使用默认的pip install turtle无法安装成功，会报错，下载源码安装成功，特此记录。

步骤

首先，下载官网turtle源码，官网地址：turtle-0.0.2

这时，直接解压后安装是无法安装的，因为turtle是Python2的库，语法是Python2，需要修改

修改文件setup.py

#!/usr/bin/env python

install_requires = ["Twisted>=8.0.1", "PyYAML>=3.0.8"]

setup = setuptools.setup

autosetup(

修改上述代码第40行：

except ValueError as ve:

修改第20行：

version = "0.0.2"

执行安装：

# pip install turtle的路径
pip install D:\turtle-0.0.2

安装成功如图：

结语

注意安装时需要使用管理员权限运行powershell，否则会报错。
本文使用Python3.10.4，turtle-0.0.2
