Cypress failed to download/install on our Azure DevOps build server when using Nexus as NPM registry

Current behavior:

We are using Nexus as a repository for all our binaries. Therefore we have configured NPM as following. .npmrc containing: registry=http://nexus.ourInternalDomain.nl/repository/npm-all

I have verified the availability of the binary in Nexus. It’s available with the following URL: http://nexus.ourInternalDomain.nl/repository/npmjs/cypress/-/cypress-4.9.0.tgz

During the installation on our Azure DevOps build server i get the following message:

Somehow Cypress is not getting downloaded from our Nexus server, while all other dependancies (for example: cypress-ntlm-auth) are succesfully downloaded. On our build server a proxy to the internet is not allowed, therefore all binaries have to come from Nexus.

Desired behavior:

I would like to see Cypress getting downloaded and installed from our Nexus server. Using the ‘CYPRESS_INSTALL_BINARY’ setting is also not an option as it will then fail to unzip as Nexus uses .tgz format. Besides that i want the versioning being driven by the package.json and not to update the build server script with each version upgrade.

Versions

I tested with version following versions: Cypress: 4.8.0 and 4.9.0 NodeJS: v12.18.1 NPM: 6.14.5

There is an accepted answer on stack overflow here that suggests using a generic remote repository to cache the binary, and setting the mirror variable to make the cypress installer download from nexus
