每当我尝试使用 TexStudio 编译任何 TeX 文档时，都会收到此错误：
该命令已扩展至 11 级。是否要继续扩展“txs:///pre-compile | txs:///conditionally-recompile-bibliography”？
如果我按“确定”，则会一次又一次地收到相同的错误，错误号码也不同，依此类推。如果我按“取消”，则可以退出此消息。
我该如何解决这个烦人的问题？
我想在不删除所有配置的情况下解决它（因为我有一些 knitr 和双向导航选项）。
我猜这与我的配置有关。
重新安装程序并不能解决问题。
这是 texstudio.ini 的内容，其中删除了一些不重要的行。

PD：最后我决定删除配置文件。看来可以了。现在预编译字段是空的。
答案1
正如@Ulrike Fischer 在评论中所说，Tools\Commands\pre-compile调用自身。这会导致无限循环。删除或修改条目precompile将解决此问题。
