![为什么 pip install turtle(图形)会出错](https://linux22.com/image/1612107/%E4%B8%BA%E4%BB%80%E4%B9%88%20pip%20install%20turtle%EF%BC%88%E5%9B%BE%E5%BD%A2%EF%BC%89%E4%BC%9A%E5%87%BA%E9%94%99.png)
安装时出现以下错误turtle
,我该怎么办?
$ sudo pip install turtle --proxy http://10.144.1.10:8080

我使用的是 Fedora 31,pip 版本:
$ pip --version
pip 19.1.1 from /usr/lib/python3.7/site-packages/pip (python 3.7)
其他一些python库也可以成功安装,例如:
$ sudo pip install scipy --proxy http://10.144.1.10:8080

顺便说一句,turtle 似乎没有安装在我的 python 中......
$ python

>>> import turtle

ModuleNotFoundError: No module named 'turtle'

概括:
turtle graphics
是 python3 标准库的一部分,无需安装。如果import turtle
出现“没有名为... 的模块”之类的错误,可以通过以下方法解决,例如在 Fedora 中,sudo dnf install python3-tkinter
答案1
龟图形已经包含在Python标准库中。
还安装python3-tkinter来自默认 Fedora 存储库的软件包。python3-tkinter 是一个使用 Tk 编写可移植 GUI 应用程序的模块,适用于 Python 3.x。然后尝试运行此 Python 代码来绘制一个圆圈。
import turtle
t = turtle.Turtle()
t.circle(50)
您尝试安装的软件包sudo pip install turtle
是 HTTP 代理软件包。它不是适合 Turtle 图形的软件包。
