Heroku无法使用bcrypt部署node.js

在向我的服务器添加bookshelf安全密码后，heroku在部署我的服务器时失败，它一直说它无法安装bcrypt

我曾尝试跟踪heroku疑难解答Node.js部署站点，但没有帮助，我曾尝试安装bcrypt，卸载它并安装bcryptjs，但没有帮助，我不知道现在该怎么办，有人能帮忙吗？

即使节点模块不应按评论中所述推送，问题似乎出在节点gyp上，而不是节点_模块本身。 我建议从bcrypt包切换到bcryptjs。它是用js编写的，性能稍差，但它不需要python依赖项，这使得构建过程不那么复杂。API是相同的，所以在代码中更改它是很简单的。这不完全是对你问题的回答，但我希望你觉得它有帮助

我会发表评论，而不是发布答案，但我的声誉不足以做到这一点。

不要推送节点模块，让Heroku为您在dyno中安装它们。我已将节点模块添加到.gitignore文件中，但这无助于您将其从正在推送的提交中删除吗？否则你只会忽略将来对它的更改。好吧，我怎么做？你读过了吗？例如，您提到尝试使用bcryptjs，但可能您推送到存储库的node_模块中仍然有bcrypt包，并且它以某种方式影响了构建过程，即使它没有在package.json中指定。我确实尝试过，正如我在文章末尾提到的，它不起作用，但是删除node_模块起作用
