我需要一些帮助来运行我的第一个开源项目

Question

我需要一些帮助来获得我想要在我的机器上运行的第一个开源项目。我有一台运行 Big Sur 11.1 (20C69) 的 2018 MacBook Pro 15 英寸。我使用 VS Code 作为我的 IDE。我已经为我的项目分叉并克隆了存储库。

我已按照说明如何让应用在此处运行：

https://github.com/bancodobrasil/stop-analyzing-embed

以下是有关如何贡献的说明：

https://github.com/bancodobrasil/stop-analyzing-embed/blob/master/CONTRIBUTING.md

这是我被分配的问题，我将继续努力：

https://github.com/bancodobrasil/stop-analyzing-embed/issues/72

我先运行“npm install”，然后“npm run dev”。

这是我在终端中遇到的错误：

The default interactive shell is now zsh.
To update your account to use zsh, please run chsh -s /bin/zsh.

谁能帮我把它运行起来。

谢谢，

Answer 1

错误信息告诉我们yarn 没有安装。查看package.json 中的dev 脚本，我们可以看到实际运行的命令：

"dev": "REACT_APP_BACKEND_URL=http://localhost:8008 yarn start",

问题是它没有在package.json 中列为（开发-）依赖项（您可能想为此创建一个PR），因此在执行npm i 时不会安装它。

要解决这个问题并安装 yarn，你应该运行以下命令： npm i -D yarn 或使用 npm i -g yarn 全局安装。
