reactjs - 运行 'react-dom' 时无法解析 '/path/node_modules/gatsby-react-router-scroll' 中的 "gatsby-develop"

Question

更新

事实证明，从我的 gatsby-config.js 中删除 gatsby-plugin-preact 可以解决这个问题。我不知道为什么，我想使用 preact

Here is the project on Github

我开始了这个项目:

gatsby 新的 gatsby-starter-default https://github.com/gatsbyjs/gatsby-starter-default

我运行 gatsby develop 并得到

 ERROR #98124  WEBPACK

Generating SSR bundle failed

Can't resolve 'react-dom' in '/path/node_modules/gatsby-react-router-scroll'

If you're trying to use a package make sure that 'react-dom' is installed. If you're trying to use a local file make sure that the path is correct.

File: node_modules/gatsby-react-router-scroll/scroll-container.js

not finished Generating image thumbnails - 7.221s

我已经尝试过 rm -rf node_modules && npm install npm update npm i react-dom npm i react- router-dom 这并没有改变任何东西

Answer 1

从 Gatsby v1 迁移到 v2 时可能会出现此错误。此处提供官方升级指南:https://www.gatsbyjs.com/docs/reference/release-notes/migrating-from-v1-to-v2/

在我的案例中，我必须执行的步骤是:

1. 从 gatsby-link 更改为 gatsby
2. 安装react & react-dom

在您的情况下，可能会更新到 gatsby-plugin-preact 的最新版本:https://www.gatsbyjs.com/plugins/gatsby-plugin-preact/
