我删除了我的node_modules文件夹，以修复以前的错误，现在我被困在另一个和另一个，我甚至忘记了最初的错误。每次我尝试运行npm install或尝试安装bcrypt时，我都会得到相同的错误。

我已尝试删除包锁。并在包中指定一个主条目。
我被告知在安装bcrypt之前运行这个代码npm install --global --production windows-build-tools根据他们的[github wiki][1]但每次我尝试安装它，(我以admin身份运行powershell)它永远不会完成。它只写了completed in 28，没有结束。我现在被困住了，很沮丧。我同样试图安装set-blocking，即使我不知道它是什么，但我看到错误说模块丢失，所以我尝试安装它，但仍然没有工作。给了我相同的错误说但这一次不同的模块是失踪。

现在我很困惑，它变成了一个痛苦的屁股。请有人知道我能做什么，因为我已经尝试了所有的选择，我可以。[1]: https://github.com/kelektiv/node.bcrypt.js/wiki/Installation-Instructions microsoft windows
我有同样的问题，并通过将package.json文件中的bcrypt版本手动更改为"bcrypt": "^5.0.1",来解决。
然后再次运行npm i，不会出现任何错误。
清理NPM缓存
npm cache clean --force
然后安装你的包
make in the package "type: module">
