npm ERR! code UNABLE_TO_GET_ISSUER_CERT_LOCALLY

How to Fix “npm ERR! code UNABLE_TO_GET_ISSUER_CERT_LOCALLY” Error

If you are a JavaScript developer, chances are you have encountered the “npm ERR! code UNABLE_TO_GET_ISSUER_CERT_LOCALLY” error at some point. This error occurs when npm, the package manager for Node.js, is unable to get the issuer certificate locally. It can be frustrating, but don’t worry, there are a few solutions you can try to resolve this issue.

Solution 1: Update npm

The first solution you can try is to update npm to the latest version. Sometimes, outdated versions of npm can cause certificate-related issues. To update npm, open your terminal or command prompt and run the following command:

npm install -g npm

This command will update npm to the latest version. Once the update is complete, try running your npm command again and see if the error persists.

Solution 2: Configure npm to Use a Different Registry

If updating npm doesn’t solve the issue, you can try configuring npm to use a different registry. The default registry for npm is the npm public registry, but sometimes it can have certificate-related problems. To switch to a different registry, follow these steps:

1. Open your terminal or command prompt.
2. Run the following command to set the registry to the Yarn registry:

npm config set registry https://registry.yarnpkg.com/

Alternatively, you can use other popular registries like npmjs or Taobao:

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

After setting the registry, try running your npm command again and see if the error is resolved.

Solution 3: Disable Strict SSL

If the above solutions don’t work, you can try disabling strict SSL verification in npm. This solution should be used with caution as it bypasses certificate validation, which can pose security risks. To disable strict SSL, run the following command:

npm config set strict-ssl false

Note that disabling strict SSL should only be a temporary solution, and you should consider enabling it again once the issue is resolved.

Hopefully, one of the above solutions helped you resolve the “npm ERR! code UNABLE_TO_GET_ISSUER_CERT_LOCALLY” error. Remember to use these solutions responsibly and consider the security implications of bypassing certificate validation.

Happy coding!
