"npm install" 不适用于从 github 中提取的 React 项目

Question

我正在使用 ubuntu 20.04.4 LTS。 我正在尝试在本地安装一个反应项目。

我尝试从 github 克隆 de repo，并在本地安装 React 应用程序，这样做：

git clone https://github.com/OpenClassrooms-Student-Center/7008001-Debutez-avec-React.git

然后

npm install --verbose

但这行不通。 这是输出：

npm verb cli   '/home/lblk/.nvm/versions/node/v17.6.0/bin/npm',
npm verb cli   'install',
npm verb cli   '--verbose'
npm verb cli ]

我搜索了一会儿，但我就是不明白... 您可能已经从我尝试安装的存储库中了解到，我正在学习编码和反应 :)

感谢您的帮助

Answer 1

将您的分支更改为分配分支之一，例如：https://github.com/OpenClassrooms-Student-Center/7008001-Debutez-avec-React/tree/P2C2-Begin

您当前的分支没有错误提示的 package.json 文件，因此您无法安装节点模块

Answer 2

你应该做

npm init

在项目的根目录中。它将创建 package.json 文件等。然后就可以使用npm install
