deno x

deno x 会从 npm 或 JSR 执行一个包，而不会将其永久安装。它类似于 npm 生态系统中的 npx。

安装 `dx` 别名 Jump to heading

为方便起见，你可以将 deno x 安装为一个独立的 dx 二进制文件，默认使用所有权限运行：

deno x --install-alias

然后直接使用它：

dx npm:create-vite my-app

你可以自定义别名名称：

deno x --install-alias=denox

基本用法 Jump to heading

运行一个 npm 包：

deno x npm:create-vite my-app

运行一个 JSR 包：

deno x jsr:@std/http/file-server

工作原理 Jump to heading

deno x 会将包下载到全局缓存中（如果尚未缓存），解析该包的二进制入口点，并执行它。该包不会被添加到你项目的 deno.json 或 package.json 中。

权限 Jump to heading

执行的包将使用你指定的权限运行：

deno x --allow-read --allow-net npm:serve .

或者授予所有权限：

deno x -A npm:create-vite my-app

Command line usage:

deno x [OPTIONS] [SCRIPT_ARG]...

Execute a binary from npm or jsr, like npx

Type checking options Jump to heading

--check<CHECK_TYPE>optional

--no-check<NO_CHECK_TYPE>optional

Skip type-checking. If the value of "remote" is supplied, diagnostic errors from remote modules will be ignored.

Dependency management options Jump to heading

--cached-only

Require that remote dependencies are already cached.

--frozen<BOOLEAN>optional

Error out if lockfile is out of date.

--import-map<FILE>

Load import map file from local file or remote URL.

--lock<FILE>optional

Check the specified lock file. (If value is not provided, defaults to "./deno.lock").

--no-lock

Disable auto discovery of the lock file.

--no-npm

Do not resolve npm modules.

--no-remote

Do not resolve remote modules.

--node-modules-dir<MODE>optional

Sets the node modules management mode for npm packages.

--reload, -r<CACHE_BLOCKLIST>optional

Reload source code cache (recompile TypeScript) no value Reload everything jsr:@std/http/file-server,jsr:@std/assert/assert-equals Reloads specific modules npm: Reload all npm modules npm:chalk Reload specific npm module.

--vendor<vendor>optional

Toggles local vendor folder usage for remote modules and a node_modules folder for npm packages.

Options Jump to heading

--allow-scripts<PACKAGE>optional

Allow running npm lifecycle scripts for the given packages Note: Scripts will only be executed when using a node_modules directory (--node-modules-dir).

--cert<FILE>

Load certificate authority from PEM encoded file.

--conditions<conditions>

Use this argument to specify custom conditions for npm package exports. You can also use DENO_CONDITIONS env var. .

--config, -c<FILE>

Configure different aspects of deno including TypeScript, linting, and code formatting. Typically the configuration file will be called deno.json or deno.jsonc and automatically detected; in that case this flag is not necessary.

--env-file<FILE>optional

Load environment variables from local file Only the first environment variable with a given key is used. Existing process environment variables are not overwritten, so if variables with the same names already exist in the environment, their values will be preserved. Where multiple declarations for the same environment variable exist in your .env file, the first one encountered is applied. This is determined by the order of the files you pass as arguments.

--install-alias<install-alias>optional

Creates a dx alias so you can run dx instead of deno x .

--location<HREF>

Value of globalThis.location used by some web APIs.

--minimum-dependency-age<minimum-dependency-age>

(Unstable) The age in minutes, ISO-8601 duration or RFC3339 absolute timestamp (e.g. '120' for two hours, 'P2D' for two days, '2025-09-16' for cutoff date, '2025-09-16T12:00:00+00:00' for cutoff time, '0' to disable).

--no-config

Disable automatic loading of the configuration file.

--preload<FILE>

A list of files that will be executed before the main module.

--require<FILE>

A list of CommonJS modules that will be executed before the main module.

--seed<NUMBER>

Set the random number generator seed.

--v8-flags<V8_FLAGS>optional

To see a list of all available flags use --v8-flags=--help Flags can also be set via the DENO_V8_FLAGS environment variable. Any flags set with this flag are appended after the DENO_V8_FLAGS environment variable.

--yes, -y

Assume confirmation for all prompts.

Debugging options Jump to heading

--inspect<HOST_PORT>optional

Activate inspector on host:port [default: 127.0.0.1:9229]. Host and port are optional. Using port 0 will assign a random free port.

--inspect-brk<HOST_PORT>optional

Activate inspector on host:port, wait for debugger to connect and break at the start of user script.

--inspect-wait<HOST_PORT>optional

Activate inspector on host:port and wait for debugger to connect before running user code.
