Scoped Packages - "yarn add" (not "yarn") throws error

What is the current behavior?

Yarn add command cannot install this published package: https://www.npmjs.com/package/@google-cloud/translate

$ yarn add @google-cloud/translate
yarn add v1.3.2
[1/4] Resolving packages...
error An unexpected error occurred: "https://registry.yarnpkg.com/@google-cloud/
translate: Not found".

npm can install it correctly:

$npm install @google-cloud/translate --save

"yarn" does install it correctly if it is in the package.json, it is just "yarn add" that fails.

Interestingly, bluebird gives a slightly different error:

$ yarn add @types/bluebird
yarn add v1.3.2
[1/4] Resolving packages...
error Couldn't find package "@types\\bluebird" on the "npm" registry.

Both work from package.json, and wrapping them in quotes in yarn add doesn't matter.

Please mention your node.js, yarn and operating system version.
yarn 1.3.2
node v8.9.4
Windows 7

Seems to work OK for me.

Maybe try upgrading to yarn v1.4 and see if it's already fixed?

No, I still see the issue on windows 7.

Still an issue on win10 with yarn 1.6.0
Seems like it has something to do with scoped packages. I don't have problem installing those without '@'

$ yarn add @ngx-translate/core
yarn add v1.6.0

error An unexpected error occurred: "https://registry.yarnpkg.com/@ngx-translate/core: 
Not found".

I still can't reproduce this. Tried on Win 10, yarn 1.5.1, powershell and it still worked for me. If someone why can consistently reproduce this can help debug, we would appreciate it.

What should happen is that yarn uses the url https://registry.yarnpkg.com/@google-cloud%2ftranslate but instead it is putting a / instead of the %2f.

I was playing around and found out it doesn't happen in windows terminal, but it fails when attempting yarn add @ngx-translate/core in git bash.

Can confirm this issue. Package: https://www.npmjs.com/package/@types/react I realize now it's because of a typo: types/react (correct) vs typed/react (what i tried). Sorry for wasting everyone's time.

$> yarn add --dev @typed/react

Problem persists after upgrading to node 9.11.1 and yarn 1.6.0. Same if I add the package to my package.json:

$> yarn                                                                                                             14:33:58
