npm install 不再有效，但一小时前完成

如何解决npm install 不再有效，但一小时前完成

有人能帮我理解这里发生了什么吗，一小时前加载良好，但现在不行，我删除了节点模块并运行 npm cache clear --force，但仍然没有。这是我得到的错误。我确信这真的很简单，我对 javascript 完全陌生，所以它可能比你想象的更明显。

有没有熟悉这个的人，有人建议我安装python2.7和错误消息中的其他库。我无法阅读 javascript，我正在学习它，但我知道这既不是 python2.7 的问题，也不是“node-gyp”的问题，因为当节点运行良好时，这两个都没有安装。这确实是一个新手问题，必须有一个简单的解决方法。
