Preface

Windows is really disgusting! ! ! Not only will there be a lot of junk files, but sometimes some software (normal software) cannot be installed for no apparent reason. A long time ago, I wanted to learn Koa2 and planned to upgrade the nodejs version to experience the new features of ES6 and ES7 such as aync and await. However, I couldn't install nodejs and I couldn't uninstall the old version of nodejs. I was at a loss and put it aside for a while. Time, tonight I want to take a look at D3 to prepare for learning, and use Koa to make a demonstration learning and practice project. I am determined to check the information and solve the nodejs installation error problem.

The hard work paid off and it was finally solved, so I recorded it in this article.

When I was desperate, I saw an article on the Internet that perfectly solved it. It was still a permission problem!
