所以我刚刚重新安装了Anaconda，设置了我的环境，打开了Spyder并收到此错误消息：

Answer 1

是的，我也面临着同样的问题。

尝试重新安装软件包：

对于 Pip用户：

pip uninstall matplotlib

对于 Pip3用户：

pip3 uninstall matplotlib

重新安装：

pip install matplotlib

pip3 install matplotlib

Answer 2

这刚好发生在我身上，原来是我在工具>首选项>终端ipython>图形>图形输出> Gtk3中修改了

将其更改为自动或其他，它对我有用

我收到此错误“设置Matplotlib后端时出现以下错误！”打开Spyder时
