Getting Started with OpenUPM-CLI

This article is a step-by-step tutorial on how to install openupm-cli and manipulate the package manifest file in the terminal. It can work with various shells:

Not a fan of a command-line tool?

If you are unfamiliar with the command-line, you can still use other installation options available on the package page.

Installing OpenUPM-CLI

OpenUPM-CLI requires Node.js v16 or aboveopen in new window.

Let's verify the Node.js installation by printing the npm version (the node package manager where UPM is inspired from).

$ npm -v

It is recommended to install the openupm-cli globally so you can use it from any path.

$ npm install -g openupm-cli
C:\Users\openupm\AppData\Roaming\npm\openupm -> C:\Users\openupm\AppData\Roaming\npm\node_modules\openupm-cli\bin\openupm + openupm-cli@1.1.0
updated 2 packages in 12.177s

Let's verify the openupm-cli installation by printing the version.

$ openupm --version

Installing a UPM Package

The next step is creating a new Unity project, located at the path ~/Document/projects/hello-openupm.

Let's install Unity Addressable Importeropen in new window, a helper package to manage addressable assets. First, you need to identify the package name.

# go to the unity project folder
$ cd ~/Document/projects/hello-openupm

# search package by keyword
$ openupm search addressable
│ Name                                     │ Version            │ Date       │
│ com.littlebigfun.addressable-importer    │ 0.16.1             │ 2023-02-08 │

It returns the package name com.littlebigfun.addressable-importer.


You can directly copy the install command from the package detail page of the openupm website.

Let's install the package via the add command.

$ openupm add com.littlebigfun.addressable-importer
added: com.littlebigfun.addressable-importer@0.16.1
manifest updated, please open the Unity project to apply changes

It returns that the package version 0.16.1 was added to the manifest file.

Go back to the Unity editor, wait for the package manager to resolve package changes. Then you shall see the com.littlebigfun.addressable-importer appears in the package manager window.

Install package

Understanding Manifest Changes

To understand the underlying changes of the manifest file, let's print the JSON content of Packages/manifest.json.

$ cat Packages/manifest.json
  "dependencies": {
    "com.littlebigfun.addressable-importer": "0.16.1"
  "scopedRegistries": [
      "name": "package.openupm.com",
      "url": "https://package.openupm.com",
      "scopes": [

The openupm-cli adds com.littlebigfun.addressable-importer to dependencies. It also modified the scopedRegistries to link the com.littlebigfun.addressable-importer namespace with the openupm registry.
