将 bookshelf-secure-password 添加到我的服务器后，heroku 无法部署我的服务器，它一直说无法安装 bcrypt。

我尝试关注 heroku Troubleshooting Node.js Deploys site https://devcenter.heroku.com/articles/troubleshooting-node-deploys 但没有帮助，我尝试安装 bcrypt，卸载它并安装 bcryptjs 但没有帮助，我不知道现在该怎么办，谁能帮忙？

Answer 1

尽管不应该像 cmets 中提到的那样推送 node_modules，但问题似乎在于 node-gyp，而不是 node_modules 本身。 我建议从 bcrypt 包切换到 bcryptjs。它是用js编写的，性能稍差一些，但它不需要python依赖，这使得构建过程不那么复杂。 API 是相同的，因此在您的代码中更改它是微不足道的。这并不完全是您问题的答案，但我希望它对您有所帮助。

我会发表评论而不是发布答案，但我的声誉还不够高，无法做到这一点。
