问题现象：

cursor搜索插件的时候提示错误，无法搜索安装插件

error while fetching extensions.failed to fetch

问题原因

cursor默认安装使用的并不是vs code的插件市场，国内网络有时候打不开

解决

修改插件市场地址并重启cursor

打开cursor安装目录下的resources\app\product.json文件，修改extensionsGallery中属性resourceUrlTemplate、serviceUrl值，修改后值清单如下：

"extensionsGallery": {"galleryId": "cursor","itemUrl": "https://marketplace.cursorapi.com/items","controlUrl": "","extensionUrlTemplate": "https://www.vscode-unpkg.net/_gallery/{publisher}/{name}/latest","recommendationsUrl": "","nlsBaseUrl": "https://www.vscode-unpkg.net/_lp/","serviceUrl": "https://marketplace.visualstudio.com/_apis/public/gallery","itemUrl": "https://marketplace.visualstudio.com/items","publisherUrl": "https://marketplace.visualstudio.com/publishers","resourceUrlTemplate": "https://{publisher}.vscode-unpkg.net/{publisher}/{name}/{version}/{path}",

需改完毕后重启cursor即可
