pnpm install
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 | no network requests |
pnpm i --frozen-lockfile | pnpm-lock.yaml is not updated |
pnpm i --prefer-frozen-lockfile | when possible, pnpm-lock.yaml is not 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-or-not 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 if 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 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
