我试图为我的应用程序构建一个snapcraft。这是我第一次使用snapcraft。该应用程序包含三个“应用程序”，我可以为单个部分运行舞台，即snapcraft stage a --use-lxd，但当我尝试运行它们组合时，即snapcraft prime --use-lxd构建卡在一些2023-01-08 16:22:11.505 check if Part('websocket'):Step.PULL is outdated \ (31013.8s)上
我试过在运行snapcraft prime命令之前构建各个部分，它们都成功了，没有出现可忽略的错误，所以我真的不明白为什么它不跳过这些阶段。
我觉得无论是什么试图检查如果拉是过时的是在某种无限的目录递归，因为即使在31305.6s它仍然没有处理。任何想法，我可以改善我的snapcraft？
