当我为我的hapi js项目安装bcrypt模块时，它尚未安装，显示为
node-pre-gyp install --fallback-to-build
我试图通过运行进行安装；
npm i node-pre-gyp
但是它不起作用。
错误：

我建议您使用bcryptjs
这可能是因为您没有使用稳定版本的节点。检查npm here
上的文档
node-gyp仅适用于稳定/已发布的节点版本。由于bcrypt模块使用node-gyp进行构建和安装，因此需要稳定版本的node才能使用bcrypt。如果不这样做，则可能会看到以下错误开头：
gyp ERR! stack Error: "pre" versions gyp ERR! stack Error: "pre" versions of node cannot be installed, use the --nodedir flag instead

尝试卸载bcrypt并安装bcryptjs
npm install --save bcryptjs && npm uninstall --save bcrypt
答案 2 :(得分：0)
如果您想使用bcrypt，
npm install --build-from-resource
如果上述命令不能解决您的问题，而不能解决fsevents （（仅在使用时）），所以对于本次运行
npm install fsevents
如果问题仍然存在，而不是您的节点版本和grpc版本存在问题，请click here for more info
