The documentation listed for Azure Devops Server 1.2 patch 10 lists the Configure TFX and Update tasks using TFS, but I'm unable to follow those steps for the on premise version of Azure Devops Server. When I click the link for Upload Tasks to the Project Collection, it switches to the documentation for Azure Devops Services, not Azure Devops Server, which makes me think it doesn't apply to Azure Devops Server; especially since I cannot run the command to install tfx-cli. Please clarify which steps are for Azure Devops server and which apply only to Azure Devops Services.
When I clicked on the link to upload tasks to project collection, I need more details on the step to install tfx-cli. I'm able to install node.js, but the npm command doesn't work.

Here you may use that from the document:
then check the instructions on the release page:
