I had the same problem on windows! Maybe my answer will help someone!
我在 Windows 上遇到了同样的问题！也许我的回答会对某人有所帮助！
If you use gmon windows you should download windows binaries hereand add gm.exeto your windows environment PATHvariable. After that you have to restart your PC.
Then install corresponding node package with npm install gmand it will work! ;)
如果您gm在 Windows 上使用，您应该在此处下载 Windows 二进制文件并添加gm.exe到您的 Windows 环境PATH变量中。之后，您必须重新启动PC。然后安装对应的node包npm install gm就可以了！;)

When installing ImageMagick from https://imagemagick.org/script/download.php, be sure to check the option to "Install legacy utilities (convert)".
从https://imagemagick.org/script/download.php安装 ImageMagick 时，请务必选中“安装旧实用程序（转换）”选项。
