我在导入 matplotlib 时收到此引用。

import matplotlib.pyplot as plt

PermissionError: [Errno 13] Permission denied: '/Library/Fonts/WarnockPro-Subh.otf'

我该如何解决？

【问题讨论】：

如果您突出显示所有回溯然后选择括号，这将更容易阅读，这样会更好地格式化它。我尝试对其进行编辑，但出现错误。

标签： python matplotlib anaconda spyder

【解决方案1】：

执行该进程的用户似乎无权访问文件/Library/Fonts/WarnockPro-Subh.otf 或其父目录之一。

你试过chown文件或目录吗？

chown user_name file
chown user_name folder
chown -R user_name folder #recursive

【讨论】：

我还是 python 新手，但我尝试 chown 它并且我得到 Errno 1 operation not allowed
以具有 sudo 权限的用户身份进行操作。
