错误：/app/node_modules/bcrypt/lib/binding/bcrypt_lib.node：无效的ELF标头

Question

我正在尝试将REST API部署到heroku。但是，该应用程序无法正常工作。在应用程序日志中，我得到了此

这似乎与bcrypt模块有关。我尝试了此处建议的解决方案：https://github.com/kelektiv/node.bcrypt.js/issues/595和https://github.com/kelektiv/node.bcrypt.js/issues/635

例如：npm rebuild bcrypt --build-from-source

这里是package.json文件：

{
  "name": "server",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "bcrypt": "^3.0.6",
    "body-parser": "^1.18.3",
    "cors": "^2.8.4",
    "cron": "^1.7.2",
    "express": "^4.16.3",
    "jsonwebtoken": "^8.3.0",
    "jwt-simple": "^0.5.6",
    "mapnik": "^4.3.1",
    "mkdirp": "^0.5.1",
    "mongoose": "^5.7.1",
    "multer": "^1.4.1",
    "nodemailer": "^6.3.0",
    "request": "^2.88.0",
    "ug": "0.0.8"
  }
}

这些解决方案都不适合我！我该如何解决这个问题？

我有同样的问题，但使用Docker。原来node_modules文件夹正在上传。确保将node_modules添加到您的.gitignore（和/或.dockerignore）中
