Error while installation

[assang]

Hi Devs,

I am unable to install using npm install @siteimprove/alfa-act or any other package

Gets Error I have added .npmrc file but still gives this error. Do I need any credentials or configuration?
npm ERR! code UNABLE_TO_GET_ISSUER_CERT_LOCALLY
npm ERR! errno UNABLE_TO_GET_ISSUER_CERT_LOCALLY
npm ERR! request to https://npm.pkg.github.com/@siteimprove%2falfa-act failed, reason: unable to get local issuer certificate

Hi there and thanks for reaching out! It sounds like you haven't yet set up authentication for GitHub Packages, which is currently required to consume both public and private packages: https://docs.github.com/en/free-pro-team@latest/packages/guides/configuring-npm-for-use-with-github-packages#authenticating-to-github-packages

Did you manage to set up authentication, @assang?

No it is giving other error. (I have added taken as @Siteimprove:registry=https://npm.pkg.github.com/:_authToken=************************** )

Now Error is:
npm ERR! code E401
npm ERR! Unable to authenticate, need: Basic realm="GitHub Package Registry"

npm ERR! A complete log of this run can be found in:

Did you add the token by doing npm login --scope=@siteimprove --registry=https://npm.pkg.github.com? If so, I imagine that the token provided might simply miss the necessary permissions; at a minimum, it needs the read:packages scope:

I tried the same steps again and now getting error. Does it mean I need some permission from npm repo or alfa repo?

The issue lies with authentication on your end as there's nothing needed from our end for you to consume public packages from the GitHub npm registry. If you're in need of more help with authentication beyond what the GitHub docs provide, I'd recommend reaching out to the Support Community: https://github.vviipp.vipmunity/c/github-help/48
