Python ImportError:找不到MagickWand共享库

下面显示了我试图运行代码时的响应，即未找到MagickWand共享库且未安装imagemagick库。所以我尝试安装，但它显示它已经安装了？对于故障排除的下一步有什么建议吗

现在调查这件事是行不通的。仍在寻找解决方案您希望我们修复一些看不到的代码吗？来吧，再努力一点，展示StackOverflow所需的代码。@MarkSetchell上面的文章展示了相关的代码问题。如果你认为你需要更多，你想要什么？从字面上说，它张贴每一行与一个问题。问题不在于代码，而在于安装的软件包。更确切地说，找不到共享库。pip包存在依赖性问题，与代码无关。
