我正在尝试制作一个小样式包，以便制作一些带有图标等的漂亮块。我正在使用environpackage + tikz。实际上，文档编译并向我显示了我的框，但出现错误，指出某些环境未关闭。
我创建了一个带有包的“iconbox”环境environ，它可以接受一些参数（标题、图标、颜色……），我想用它来概括一些框：info框、danger框……
当我想创建一个使用我创建的图标框的新环境时，问题就开始了。
如果我想使用\NewEnviron它来调用另一个，LaTeX 会在递归中崩溃。
如果我使用旧版newenvironment，LaTeX 会说我没有关闭图标框块。
当然，我尝试过\beginiconbox在\endiconbox开始和结束块中但它不起作用。
这是一个“复制/粘贴”应该给你的问题

它会生成这样的框：
但是...有错误...
那么我该怎么办？
多谢。
