我看过关于这个主题的其他文章, 但我想知道,是否有办法这样做, 而不直接更改到图书馆的目录, 或明确指定绝对路径, 例如通过 sys. path. 附录或使用 PATH 或 LASSSPATH 在 Windows 上的环境变量。 我现在要做的是加载“ jvm. dll ” 。
如果有关 DLL 不存在任何依赖关系, 则可以通过通过 ctype 工厂将绝对路径通过 DLL (您可以任意决定) 装入图书馆。 但是, DLL 往往被捆绑在一起, 并且具有相互依存性。 您最有力的赌注可能是将包含目录的 DLL 添加到 os. environ [PATH] 上, 以确保 OS 库负载器能够自动解决附属 DLL 。 注意, 如果您担心污染环境, 您可以暂时这样做 。
dll_dir = r c:fooarpath
tmp = os.environ[ PATH ]
os.environ[ PATH ] = dll_dir + ; + tmp
ctypes.LoadLibrary( dll_name )
os.environ[ PATH ] = tmp
