我正在尝试在我的 Windows 机器上启动我的 node js 服务器。在我的 ubuntu 上一切正常，它启动了但是在 Windows 上我收到以下错误:

auth.js 看起来像这样:

我的 Node 模块是:

谁能告诉我可能是什么问题？

最佳答案

您是否从您的 Ubuntu 机器上复制了 node_modules 目录？您需要从您的副本中排除该目录(我建议您将此目录添加到您的 .gitignore 文件中)因为您尝试使用的模块很可能是为 Linux 系统编译的.

如果您排除该目录并在 Windows 服务器上的该目录中运行 npm install，您的所有模块(包括 bcrypt)都将重新生成以用于 Windows。
