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

tl;dr

CommandMeaning
pnpm i --offlineno network requests
pnpm i --frozen-lockfilepnpm-lock.yaml is not updated
pnpm i --prefer-frozen-lockfilewhen possible, pnpm-lock.yaml is not updated

store

  • Default: ~/.pnpm-store
  • Type: path

The location where all the packages are saved on the disk.

The store should be always on the same disk on which installation is happening. So there will be one store per disk. If there is a home directory on the current disk, then the store is created in <home dir>/.pnpm-store. If there is no homedir on the disk, then the store is created in the root. For example, if installation is happening on disk D then the store will be created in D:\.pnpm-store.

It is possible to set a store from a different disk but in that case pnpm will copy, not link, packages from the store. Hard links are possible only inside a filesystem.

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.

network-concurrency

  • Default: 16
  • Type: Number

Controls the maximum number of HTTP requests that can be done simultaneously.

child-concurrency

  • Default: 5
  • Type: Number

Controls the number of child processes run parallelly to build node modules.

lock

  • Default: true
  • Type: Boolean

Dangerous! If false, the store is not locked. It means that several installations using the same store can run simultaneously.

Can be passed in via a CLI option. --no-lock to set it to false. E.g.: pnpm install --no-lock.

If you experience issues similar to the ones described in #594, use this option to disable locking. In the meanwhile, we'll try to find a solution that will make locking work for everyone.

ignore-scripts

  • Default: false
  • Type: Boolean

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

ignore-pnpmfile

Added in: v1.25.0

  • Default: false
  • Type: Boolean

pnpmfile.js will be ignored. Useful together with --ignore-scripts when you want to make sure that no script gets executed during install.

pnpmfile

Added in: v1.39.0

  • Default: pnpmfile.js
  • Type: path
  • Example: .pnpm/pnpmfile.js

The location of the local pnpmfile.

production[=true|false]

  • Default: false
  • Type: Boolean

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-or-not status from this flag instead.

Notes: --production is the same as --production=true. --prod is an alias of --production.

global-pnpmfile

Added in: v1.39.0

  • Default: null
  • Type: path
  • Example: ~/.pnpm/global_pnpmfile.js

The location of a global pnpmfile. A global pnpmfile is used by all projects during installation.

NOTE: It is recommended to use local pnpmfiles. Only use a global pnpmfile, if you use pnpm on projects that don't use pnpm as the primary package manager.

independent-leaves

  • Default: false
  • Type: Boolean

If true, symlinks leaf dependencies directly from the global store. Leaf dependencies are packages that have no dependencies of their own. Setting this config to true might break some packages that rely on location but gives an average of 8% installation speed improvement.

verify-store-integrity

Added in: v1.8.0

  • Default: true
  • Type: Boolean

If false, doesn't check whether packages in the store were mutated.

package-import-method

Added in: v1.25.0

  • Default: auto
  • Type: auto, hardlink, copy, reflink

Controls the way packages are imported from the store.

  • auto - try to hardlink packages from the store. If it fails, fallback to copy
  • hardlink - hardlink packages from the store
  • copy - copy packages from the store
  • reflink - reflink (aka copy-on-write) packages from the store

lockfile

Added in: v1.32.0 (initially named shrinkwrap)

  • Default: true
  • Type: Boolean

When set to false, pnpm won't read or generate a pnpm-lock.yaml file.

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: false
  • Type: Boolean

If true, pnpm doesn't generate a lockfile and fails if an update is needed.

prefer-frozen-lockfile

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

  • Default: true (from v1.38.0)
  • Type: Boolean

When true and the available pnpm-lock.yaml satisfies the package.json then a headless installation is performed. A headless installation is faster than a regular one because it skips dependencies resolution and peers resolution.

reporter

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

Allows to choose the reporter that will print info 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

use-running-store-server

Added in: v2.5.0

  • Default: false
  • Type: Boolean

Only allows installation with a store server. If no store server is running, installation will fail.

side-effects-cache

Added in: v1.31.0

Stability: Experimental

  • Default: false
  • Type: Boolean

Use and cache the results of (pre/post)install hooks.

side-effects-cache-readonly

Added in: v1.31.0

Stability: Experimental

  • Default: false
  • Type: Boolean

Only use the side effects cache if present, do not create it for new packages.

shamefully-flatten

Added in: v1.34.0

  • Default: false
  • Type: Boolean

If true, pnpm creates a flat node_modules that look almost like a node_modules created by npm or Yarn. Please only use this option when there is no other way to make a project work with pnpm. The strict node_modules created by pnpm should always work, if it does not, most likely a dependency is missing from package.json. Use this config only as a temporary fix.

strict-peer-dependencies

Added in: v2.15.0

  • Default: false
  • Type: Boolean

If true, commands fail on missing or invalid peer dependencies.

resolution-strategy

Added in: v3.1.0

  • Default: fast
  • Type: fast, fewer-dependencies

Sets the resolutions strategy used during installation.

  • fast - the default resolution strategy. Speed is preferred over deduplication
  • fewer-dependencies - already installed dependencies are preferred even if newer versions satisfy a range

use-beta-cli

Added in: v3.6.0

  • Default: false
  • Type: Boolean

When true, beta features of the CLI are used. This means that you may get some changes to the CLI functionality that are breaking changes.
