javascript - env-cmd 错误未能在 gatsby 中找到 ./.env 文件？

问题描述

我在根文件夹中有一个文件名 .env.development 。
启动服务器时，我已将 env-cmd 安装为开发依赖项

  > npm run develop

它给了我一个错误

> gatsby-starter-hello-world@0.1.0 develop I:\learngatsby
> env-cmd .env-development gatsby develop

解决方案

您可以使用您自己的带有标志的自定义.env文件设置环境变量。使用此命令设置自定义文件中定义的变量。-fenv-cmdenv'./config/myvar.env'

env-cmd -f ./config/myvar.env
