【问题描述】：
大家好，提前谢谢大家。
谁能解释一下如何处理这个错误。
我正在尝试通过 Heroku 构建 Web 应用程序的后端，但我不断收到相同的错误。在试图找出我的问题时，我已经用尽了所有选项。
我正在使用带有 Knex 的 Node.js 进行查询。 拥有 npm 版本 6.14.11 和节点版本 v12.12.0
以下是我的一些尝试：
- 我再次删除了节点模块/package-lock.json & npm install
- 安装了 sqlite3@4.2.0 和 node-pre-gyp
- 将 dotenv 作为 devDepency 移动。
我提供了以下代码：
- Heroku 错误
- Package.json
- Knex 文件
- 服务器
如果需要更多信息，请告诉我。 这是我在 Heroku 中遇到的错误：

【问题讨论】：
-
提示 #1。在 dev env 中，来自 node_modules 的 rm -rf * 然后是“npm install”，然后是“build”，然后是“heroku local”。如果一切正常，那么 git push 到 heroku 也应该可以工作
-
提示 #2 。 Heroku set env 可以在 heroku 仪表板中用于您在 dev 中使用文件 (.env) 进行的生产环境设置。在这种情况下，(dot)gitignore 将包含“.env”的条目，以免推送。
