pnpm install

Aliases: i

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

CI 環境では、ロックファイルが存在しても更新が必要な場合はインストールは失敗します。

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

コマンド	意味
pnpm i --offline	ストアからのみオフラインでインストールする
pnpm i --frozen-lockfile	pnpm-lock.yaml is not updated
pnpm i --lockfile-only	Only pnpm-lock.yaml is updated

Options

--force

依存関係の強制再インストール: ストアで変更されたパッケージを再取得し、互換性のないバージョンの pnpm で作成されたロックファイルやモジュールディレクトリを再作成します。 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. 依存パッケージがローカルで見つからない場合、インストールは失敗します。

--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

• デフォルト:
  • 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

破損した lockfile の項目を自動的に修正します。

--frozen-lockfile

• デフォルト:
  • 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. 以下のコードが CI 環境の検出に使用されています。

--merge-git-branch-lockfiles

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

--reporter=<name>

• デフォルト:
  • For TTY stdout: default
  • For non-TTY stdout: append-only
• Type: default, append-only, ndjson, silent

インストールの進行状況のデバッグ情報をターミナルにログ出力するレポーターを設定できます。

• 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. カーソル操作を行いません。
• 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

危険

Deprecated feature

バックグラウンドでストアサーバーを起動します。 インストールが完了した後も、ストアサーバーは実行し続けます。 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>

警告

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

--resolution-only
