错误如下：

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: cloudeyes@1.0.0
npm ERR! Found: sass-loader@7.3.1

解决方法：

npm i --legacy-peer-deps

解析：

npm@7 的 ERESOLVE 问题很常见，因为 npm 7.x 对某些事情比 npm 6.x 更严格。
通常，最简单的解决方案是将 --legacy-peer-deps 标志传递给 npm（例如，npm i --legacy-peer-deps），或者使用 npm@6。
如果这不能立即起作用，也许先尝试删除 node_modules 和 package-lock.json 。它们将被重新创建。
