node.js - 无密码和 mongostore

Question

我克隆了一个 github 存储库( https://github.com/rbudiharso/smsauth-example )作为无密码示例，但是当我尝试从 package.json 进行 npm 安装时

开始 pop ERR，并显示以下消息。

其中一条错误消息指出 node-gyp重建 我不知道。

另一条错误消息指出bcrypt 存在问题。

我尝试安装但失败的模块是 passwordless-mongostore (在 npm 上可用)

所以当我尝试安装node-gyp时，以下错误日志仍然存在。

所以我只想在写出所有内容之前安装并运行该项目，有人可以帮忙吗？

尽管paswordless-mongostore是一个 NPM 模块，它具有 Python 依赖项。它直接取决于bcrypt ，这直接和间接取决于 node-gyp .

node-gyp is a cross-platform command-line tool written in Node.js for compiling native addon modules for Node.js. It bundles the gyp project used by the Chromium team and takes away the pain of dealing with the various differences in build platforms.

gyp 本身是 written in Python ，并且 node-gyp 包括 Python code直接地。您看到的错误来自其 configure.js file and is triggered when Python is not found .

您至少有两个选择:

• 安装Python。

  根据您的环境，这可能从简单的一行命令到完全不可行。

• 使用不同的库，例如passwordless-mongostore-bcrypt-node .

  passwordless-mongostore 自述文件包含以下建议:

  Tokens are stored in a MongoDB database and are hashed and salted using bcrypt. If you have trouble installing bcrypt (esp. on Windows) you could also consider using the slower but pure-JS version of MongoStore.
