问题描述
我正在尝试根据文档 https://www.gatsbyjs.com/plugins/gatsby-plugin-image#installation
通过 npm 安装 gatsby-plugin-image在终端中收到以下错误：
$ npm install gatsby-plugin-image gatsby-plugin-sharp gatsby-source-filesystem gatsby-transformer-sharp
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

Package.json 来自 gatsby starter 库中的 hello world starter：
{
"name": "gatsby-starter-hello-world","private": true,"description": "A simplified bare-bones starter for Gatsby","version": "0.1.0","license": "0BSD","scripts": {

}
}
我在 GH 存储库或 Google 搜索中没有看到任何与此相关的问题。尝试了 https://www.gatsbyjs.com/docs/how-to/local-development/troubleshooting-common-errors/ 中的故障排除提示，但没有成功。没有使用 --force 运行 npm installs 的经验。有什么我应该注意的吗？如果我强制安装，我能恢复吗？提前致谢！
解决方法
您似乎正在使用 npm v7，因此对您有用的命令 according to the docs 是：
npm install gatsby@latest --legacy-peer-deps
然后，您将能够运行：
npm install gatsby-plugin-image gatsby-plugin-sharp gatsby-transformer-sharp
或者，您可以尝试通过以下方式向它们添加旧对等依赖项：
npm install gatsby-plugin-image gatsby-plugin-sharp gatsby-transformer-sharp --legacy-peer-deps
