matplotlib导入错误python

Question

我在 Mac 上安装了 matplotlib，它是成功的。输入后

import matplotlib.pyplot as plt

在我的代码中出现以下错误：

Traceback (most recent call last):
File "q2.py", line 5, in <module>
import matplotlib.pyplot as plt

我按照以下链接中的安装说明进行操作：

安装没有问题。有谁知道为什么会这样？

谢谢！

我知道这个问题有点陈旧，但我最近遇到了同样的问题，在网上找不到解决方案。我想我的调试可能会帮助其他人......

显然与 /usr/local/lib/ 中的 libgcc_s.1.dylib 和 libstdc++.6.dylib 库不兼容。我备份了这些文件，然后从 /usr/lib/ 中找到的文件进行 sym 链接

sudo mv /usr/local/lib/libgcc_s.1.dylib /usr/local/lib/libgcc_s.1.dylib.old
sudo mv /usr/local/lib/libstdc++.6.dylib /usr/local/lib/libstdc++.6.dylib.old

sudo ln -s /usr/lib/libgcc_s.1.dylib /usr/local/lib/libgcc_s.1.dylib
sudo ln -s /usr/lib/libstdc++.6.dylib /usr/local/lib/libstdc++.6.dylib

我现在可以导入 pyplot 了 :)
