Solution 2:

The 600000 in the above file refers to 600000/1000 = 600 seconds, which is 5 minutes. File created in the project root directory .yarnrcwith the following code attached:

 yarn config set registry https://registry.npm.taobao.org

So it's better to keep it, replace it globally in the yarn.lockfile , and then reinstall.https://registry.yarnpkg.comhttps://registry.npmmirror.com
