如何让我的 gem 在安装时将 .dll 放入系统路径中的文件夹中？
...当然，并在卸载时将其删除。
问题是从我的 gem 调用的其他程序需要能够在系统 PATH 中找到某个文件 - 以编程方式设置 PATH 不起作用，因为这些程序正在以一种获得新环境的方式被调用。
我尝试将这些 .dll 文件作为 gemspec 中的“可执行文件”包含在内，但这似乎只会在 {ruby}/bin 文件夹中获得一些符号链接类型文件，这会导致错误，因为有问题的程序是期待实际的 .dll。
事实上，我只是在自述文件中添加了一条注释，要求人们手动将 .dll 文件复制到 PATH 中的文件夹中，但似乎应该有更好的方法来执行此操作。
任何帮助将不胜感激 - 谢谢！
... and remove it upon un-installation, of course.
The issue is that other programs being called from my gem need to be able to find a certain file in the system PATH - setting the PATH programatically doesn't work, as these programs are being called in a way that they get a fresh environment.
I tried including these .dll files as "executables" in the gemspec, but that only seems to get some symlink type files in the {ruby}/bin folder, which causes errors because the programs in question are expecting the actual .dll.
As it is, I just have a note in the README asking people to manually copy the .dll files to a folder in the PATH, but it seems like there should be a better way to do this.
Any help would be appreciated - thanks!

我猜这个dll是java类所需的本机库？
如果是这样，您可以将其放在 lib 文件夹中的某个位置，并在使用 java 类之前调用 java.lang.System.load 加载它。它不必以这种方式位于系统路径中。
I guess the dll is a native lib required by a java class?
If so, you can just put it somewhere in the lib folder and call java.lang.System.load to load it before the java class is used. It doesn't have to be in system PATH this way.
