npm ERR! Error: EPERM: operation not permitted, rename

NPM is a node package manager used to manage the node plugins in your project powered by Node.js. Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser.

Errors are a common thing in web development scenarios. We will face many challenges when used many plugins that have dependencies. Likewise, a Node JS project contains different plugins of its own and the errors will occur in the development stages.

When I execute npm install I get this error

npm install command will install all the dependencies in your project. It may return an error when your system environment is not matched or when the plugin mismatch.

Steps to reproduce

I was getting the same issue, npm cache clean fixed it for me 🙂


When you migrate your project to another system or when you have too many caches in your project this error may occur. Hope the npm cache clean will fix it for you.
