Installing private package from Github Package registry fails with not found/not authorized

问题

I created and published a private Github package. Trying to install it with yarn at first, I face the following issue:

Whether I try with yarn or npm, it cannot find the package at all although following the exact steps documented by Github (https://help.github.com/en/github/managing-packages-with-github-package-registry/configuring-npm-for-use-with-github-package-registry).

My .yarnrc:

registry "https://npm.pkg.github.com/OWNER"

With yarn, it continuously tries to look for the package at https://registry.yarnpkg.com/@GITHUB_USERNAME instead of the registry I entered above.

Remark: in .yarnrc registries need to be added following a slightly different syntax:

registry "https://npm.pkg.github.com/"

So far I started to also play around with a mix of .npmrc and .yarnrc configurations but no luck.

EDIT (Partly solved)

I figured out how to actually access the package, both using npm or - in my case - yarn. Now I face the issue of a Request failed \"401 Unauthorized\" error, although I added the credentials on top of .yarnrc:

//npm.pkg.github.com/:_authToken=AUTH_TOKEN

Doing the same in .npmrc doesn't work either.

回答1:

I found the solution which unfortunately is not well documented anywhere but a mix of different resources - and it's quite simple.

No matter whether you use npm or yarn, just have the following .npmrc in place (yarn will also include this):

registry=https://registry.yarnpkg.com/

@GITHUB_USERNAME:registry=https://npm.pkg.github.com
//npm.pkg.github.com/:_authToken=AUTH_TOKEN
always-auth=true

Some comments:

• always-auth is needed, at least when using yarn (haven't tested using npm)
• Adding the above in the .yarnrc instead doesn't work. Somehow yarn has issues when authentication is needed.
• Now you can easily install your private packages with yarn add @GITHUB_USERNAME/PACKAGE_NAME or the npm equivalent.
• Include registry=https://registry.yarnpkg.com/ for yarn or registry=https://registry.npmjs.org/ for npm

I hope this solution works also in your case. Otherwise let me know what issues you face and I'm happy to share some of the research on this topic and where the solution may hide.

回答2:

What you need to do is specify where to retrieve EACH package, with something like this in your .npmrc (I don't know the yarn syntax, but it works with yarn when it reads the .npmrc):

//registry.npmjs.org/:_authToken=<token-npm-read>
//npm.pkg.github.com/:_authToken=<token-github-package-read>
@foo:registry=https://npm.pkg.github.com
@far:registry=https://registry.npmjs.org

And then, Yarn will search @foo/mypackage1 in Github, where @far/mypackage2 will be searched in npmjs. The default registry will be kept for the others, whatever you set it to.
