Question

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

ERR开始弹出以下信息。

其中一条错误消息指出我不知道的node-gyp rebuild。

另一条错误消息指出problem with bcrypt。

我尝试安装但失败的模块是passwordless-mongostore（可在npm上找到）

因此，当我尝试安装node-gyp时，以下错误日志仍然存在。

所以我只是想在编写所有内容之前安装并运行该项目，有人可以帮助这个吗？

即使paswordless-mongostore是NPM模块，它也具有Python依赖性。它直接取决于bcrypt，它直接或间接地依赖于node-gyp。

node-gyp是一个用Node.js编写的跨平台命令行工具，用于编译Node.js的本机插件模块。它捆绑了Chromium团队使用的gyp项目，并消除了处理构建平台各种差异的痛苦。

gyp本身为written in Python，node-gyp直接包含Python code。您看到的错误来自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，这可能从简单的单行命令到完全不可行。
使用其他库，例如passwordless-mongostore-bcrypt-node

passwordless-mongostore自述文件包含以下建议：

令牌存储在MongoDB数据库中，并使用bcrypt进行散列和加盐。 如果您在安装bcrypt时遇到问题（尤其是在Windows上），您还可以考虑使用MongoStore的slower but pure-JS version。

无密码和mongostore
