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#

CommandMeaning
pnpm i --offlineInstall offline from the store only
pnpm i --frozen-lockfilepnpm-lock.yaml is not updated
pnpm i --lockfile-onlyOnly pnpm-lock.yaml is updated

Options#

--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#

Added in: v1.28.0

  • 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.

--ignore-scripts#

  • Default: false
  • Type: Boolean

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

note

This flag does not prevent the execution of pnpmfile.js

--prod, -P#

pnpm will not install any package listed in devDependencies if the NODE_ENV environment variable is set to production. Use this flag to instruct pnpm to ignore NODE_ENV and take its production status from this flag instead.

--dev, -D#

Only devDependencies are installed regardless of the NODE_ENV.

--no-optional#

optionalDependencies are not installed.

--lockfile-only#

Added in: v1.26.0 (initially named shrinkwrap-only)

  • Default: false
  • Type: Boolean

When used, only updates pnpm-lock.yaml and package.json instead of checking node_modules and downloading dependencies.

--frozen-lockfile#

Added in: v1.37.1 (initially named frozen-shrinkwrap)

  • 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.

--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, except fatal errors
  • default - the default reporter when the stdout is TTY
  • append-only (Added in v1.29.1) - the output is always appended to the end. No cursor manipulations are performed
  • ndjson - the most verbose reporter. Prints all logs in ndjson format

--use-store-server#

Added in: v1.30.0

  • 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.

--filter <package_selector>#
