我正在使用的模拟软件失败，出现以下错误消息：
[Err] [Plugin.hh:165] Failed to load plugin //Users/../catkin_ws/devel/lib/libgazebo_ros_paths_plugin.dylib: dlopen(//Users/../catkin_ws/devel/lib/libgazebo_ros_paths_plugin.dylib, 9): Library not loaded: libroslib.dylib

我查看了应用程序源代码（在Plugin.hh文件中），我发现此消息来自该行代码：
void *dlHandle = dlopen(fullname.c_str(), RTLD_LAZY|RTLD_GLOBAL);
if (!dlHandle)
{
gzerr << "Failed to load plugin " << fullname << ": "
<< dlerror() << "\n";
return result;
}
如果我理解正确的dlopen man，RTLD_LAZY应该在错误符号的情况下推迟失败，所以我认为dlopen没有失败。
那么这次失败的原因是什么？这是其中一个库上的otool输出（如果有帮助的话）：

PS：env | grep DYLD什么都不返回
PS2：我正在寻找根本原因的修复方法，而不是在另一个问题（我没有重复）中使用install_name建议的修补程序。
