无法使用 Gatsby+Ghost 启动项目

Question

我是 Gatsby 的新手，我正在尝试基于 Gatsby + Ghost 启动一个项目，但我可以解决这个问题，我立即执行来自 official github page 的命令：

$ gatsby new gatsby-starter-ghost https://github.com/TryGhost/gatsby-starter-ghost.git

根据提示：

npm ERR! Found: react@17.0.2
npm ERR! node_modules/react
npm ERR!   react@"17.0.2" from the root project

npm ERR! Could not resolve dependency:
npm ERR! peer react@"^16.9.0" from @tryghost/helpers-gatsby@1.0.50
npm ERR! node_modules/@tryghost/helpers-gatsby
npm ERR!   @tryghost/helpers-gatsby@"1.0.50" from the root project

您正在运行 React v17.0.2，这是对所需 React 版本 (^16.9.0) 的重大升级。您应该能够使用当前版本的 React 运行您的项目，但您可能需要通过以下方式安装对等依赖项：

npm install gatsby@latest --legacy-peer-deps

注意：在运行之前删除 package-lock、node_modules 和可能的 .cache 文件夹。
