pnpm install

Aliases: i

pnpm install is used to install all dependencies for a project.

In a CI environment, installation fails if a lockfile is present but needs an update.

Inside a workspace, pnpm install installs all dependencies in all the projects. If you want to disable this behavior, set the recursive-install setting to false.

TL;DR

Command	Meaning
pnpm i --offline	Install offline from the store only
pnpm i --frozen-lockfile	pnpm-lock.yaml is not updated
pnpm i --lockfile-only	Only pnpm-lock.yaml is updated

Options

--force

Force reinstall dependencies: refetch packages modified in store, recreate a lockfile and/or modules directory created by a non-compatible version of pnpm. Install all optionalDependencies even they don't satisfy the current environment(cpu, os, arch).

--offline

• Default: false
• Type: Boolean

If true, pnpm will use only packages already available in the store. If a package won't be found locally, the installation will fail.

--prefer-offline

• Default: false
• Type: Boolean

If true, staleness checks for cached data will be bypassed, but missing data will be requested from the server. To force full offline mode, use --offline.

--prod, -P

• Default:
  • If NODE_ENV is production: true
  • If NODE_ENV is not production: false
• Type: Boolean

If set, pnpm will ignore NODE_ENV and instead use this boolean value for determining the environment.

If true, pnpm will not install any package listed in devDependencies and will remove those insofar they were already installed. If false, pnpm will install all packages listed in devDependencies and dependencies.

--dev, -D

Only devDependencies are installed and dependencies are removed insofar they were already installed, regardless of the NODE_ENV.

--no-optional

optionalDependencies are not installed.

--lockfile-only

• Default: false
• Type: Boolean

When used, only updates pnpm-lock.yaml and package.json. Nothing gets written to the node_modules directory.

--fix-lockfile

Fix broken lockfile entries automatically.

--frozen-lockfile

• Default:
  • For non-CI: false
  • For CI: true, if a lockfile is present
• Type: Boolean

If true, pnpm doesn't generate a lockfile and fails to install if the lockfile is out of sync with the manifest / an update is needed or no lockfile is present.

This setting is true by default in CI environments. The following code is used to detect CI environments:

https://github.com/watson/ci-info/blob/44e98cebcdf4403f162195fbcf90b1f69fc6e047/index.js#L54-L61

exports.isCI = !!(
  env.CI || // Travis CI, CircleCI, Cirrus CI, GitLab CI, Appveyor, CodeShip, dsari
  env.CONTINUOUS_INTEGRATION || // Travis CI, Cirrus CI
  env.BUILD_NUMBER || // Jenkins, TeamCity
  env.RUN_ID || // TaskCluster, dsari
  exports.name ||
  false
)

--merge-git-branch-lockfiles

Merge all git branch lockfiles. Read more about git branch lockfiles.

--reporter=<name>

• Default:
  • For TTY stdout: default
  • For non-TTY stdout: append-only
• Type: default, append-only, ndjson, silent

Allows you to choose the reporter that will log debug info to the terminal about the installation progress.

• silent - no output is logged to the console, not even fatal errors
• default - the default reporter when the stdout is TTY
• append-only - the output is always appended to the end. No cursor manipulations are performed
• ndjson - the most verbose reporter. Prints all logs in ndjson format

If you want to change what type of information is printed, use the loglevel setting.

--use-store-server

• Default: false
• Type: Boolean

Starts a store server in the background. The store server will keep running after installation is done. To stop the store server, run pnpm server stop

--shamefully-hoist

• Default: false
• Type: Boolean

Creates a flat node_modules structure, similar to that of npm or yarn. WARNING: This is highly discouraged.

--ignore-scripts

• Default: false
• Type: Boolean

Do not execute any scripts defined in the project package.json and its dependencies.

--filter <package_selector>

warning

Filter currently does not work properly with v8 default config, you have to implicitly set dedupe-peer-dependents to false to have that work. For more info and progress please refer to #6300

Read more about filtering.

--resolution-only

Re-runs resolution: useful for printing out peer dependency issues.
