node.js - Node bcrypt 安装出现问题

Question

我正在学习sails.js 。所以我只想使用 Node 模块 bcrypt 加密密码。

npm install bcrypt是我用来安装bcrypt模块的命令，我发现它有很多依赖项，我还安装了node-gypnpm install -g node-埃及人

谁能建议我如何解决这个问题？

我在 Ubuntu 13.10 上遇到了几乎相同的问题，错误日志看起来相同，并且 bcrypt 安装在 node-gyp重建 处停止。经过一些搜索和更新 Node 和 npm 我仍然遇到同样的问题。

我终于在这里找到了解决方案:https://github.com/ncb000gt/node.bcrypt.js/issues/90问题是 ~/.node-gyp 目录没有足够的访问权限，只需删除它就可以了。这是 gyp 在编译期间存储 header 和其他构建文件的地方，如果它消失了，gyp 将重新创建它。
