当我为我的快乐js项目安装bcrypt模块时，它没有安装，它显示
类似
node-pre-gyp install --fallback-to-build
我尝试通过运行进行安装;
npm i node-pre-gyp
但它不起作用。
错误：

尝试卸载 bcrypt 并安装 bcryptjs
npm install --save bcryptjs && npm uninstall --save bcrypt
我建议你使用bcryptjs
这可能是因为您没有选择节点的稳定版本。在此处查看 npm 上的文档
node-gyp仅适用于节点的稳定/发布版本。由于bcrypt模块使用node-gyp来构建和安装，因此您需要稳定版本的 node 才能使用 bcrypt。否则，您可能会看到以下错误：
gyp ERR! stack Error: "pre" versions gyp ERR! stack Error: "pre" versions of node cannot be installed, use the --nodedir flag instead
如果你想要bcrypt 而不是
npm install --build-from-resource
如果上面的命令不能解决您的问题，那么它可能与 fsevents 有关((仅当您使用它时((因此对于此运行
npm install fsevents
如果问题仍然存在，而不是您的节点版本和 GRPC 版本的问题，请单击此处了解更多信息
