我在我的应用程序中使用了带有 eslint 和更漂亮的 airbnb 样式指南。我将它们安装到 devDependencies。我的 pacakage.json 在下面。

当 heroku 部署一个应用程序时,heroku 会删除 devDependencies。我想这就是原因。我试图将 YARN_PRODUCTION env 设置为 false。然后,我成功了。 但是,由于安装了 devDependencies,捆绑包的大小更大。我想避免它。

在使用 eslint 和 prettier to heroku 部署应用程序时如何处理 devDependencies?

【问题讨论】:

以下。我不太明白为什么在构建时会触发 eslint 【参考方案1】:

Heroku 支持自定义构建脚本,您可以在其中直接设置环境变量:

"scripts": 
    ...
    "build": "react-scripts build",
    "heroku-postbuild": "DISABLE_ESLINT_PLUGIN=true react-scripts build"
  ,

piouson 的回答可以完成这项工作,但是我发现使用以下解决方案更简洁(至少我相信)Heroku 特定问题和.env.production 文件可能会影响其他潜在的生产服务器。

【讨论】:

【参考方案2】:

偶然发现了这个问题,在网上敲了一整天后无法解决。必须在生产版本中禁用 eslint-webpack-plugin

创建文件.env.production 打开文件并添加DISABLE_ESLINT_PLUGIN=true

在 CI 期间,您仍然可以毫无问题地运行 yarn lint 或任何您的 linting 脚本,并避免这个仅在 yarn build 上发生的 webpack 问题
