为什么 pip install turtle （图形）错误

  • 772

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
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip install --user` instead.

我正在使用 Fedora 31 和 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库可以安装成功，比如：

$ 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
Python 3.7.5 (default, Dec 15 2019, 17:54:26) 
[GCC 9.2.1 20190827 (Red Hat 9.2.1-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import turtle
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'turtle'
>>>

概括：

turtle graphics是python3标准库的一部分，不需要安装。如果import turtle显示类似“No module named...”的错误，它可以通过例如在 Fedora 中解决，sudo dnf install python3-tkinter

python installation

    海龟图形已经包含在 Python 标准库中。

    还要从默认的 Fedora 存储库安装python3-tkinter包。python3-tkinter 是一个使用 Tk 使用 Python 3.x 编写可移植 GUI 应用程序的模块。然后尝试运行这个 Python 代码来绘制一个圆。

    import turtle

t = turtle.Turtle()
t.circle(50)

    您尝试安装的sudo pip install turtle包是 HTTP 代理包。它不是 Turtle 图形的正确包。
