没有调用npm package.json脚本

Question

I have the following scripts section in my projects package.json:

"scripts": {
    "seed": "node bin/seed",
    "test": "echo \"Error: no test specified\" && exit 1"
  },

If i run $ npm test I get this:

>npm test

> node-mongo-seeds@0.0.1 test C:\Users\m089269\WebstormProjects\node-mongo-seeds
> echo "Error: no test specified" && exit 1

"Error: no test specified"
npm ERR! Test failed.  See above for more details.
npm ERR! not ok code 0

If i run $ npm seed , I get this:

npm seed

Usage: npm <command>

where <command> is one of:
    add-user, adduser, apihelp, author, bin, bugs, c, cache,
    completion, config, ddp, dedupe, deprecate, docs, edit,
    explore, faq, find, find-dupes, get, help, help-search,
    home, i, info, init, install, isntall, issues, la, link,
    list, ll, ln, login, ls, outdated, owner, pack, prefix,
    prune, publish, r, rb, rebuild, remove, repo, restart, rm,
    root, run-script, s, se, search, set, show, shrinkwrap,
    star, stars, start, stop, submodule, tag, test, tst, un,
    uninstall, unlink, unpublish, unstar, up, update, v,
    version, view, whoami

npm <cmd> -h     quick help on <cmd>
npm -l           display full usage info
npm faq          commonly asked questions
npm help <term>  search for help on <term>
npm help npm     involved overview

Specify configs in the ini-formatted file:
    C:\Users\m089269\.npmrc
or on the command line via: npm <command> --key value
Config info can be viewed via: npm help config

npm@1.4.3 C:\Program Files\nodejs\node_modules\npm

Why does it recognize my test script but not my seed script?

EDIT

When I try npm run-script seed I get this error which is expected because I don't pass in a -d param:

$ npm run-script seed

> node-mongo-seeds@0.0.1 seed C:\Users\m089269\WebstormProjects\node-mongo-seeds
> node bin/seed

Populate mongo from a set of .json files.
 Usage: $ node seed

Options:
  -d  The path to your mongo db  [required]

Missing required arguments: d

npm ERR! node-mongo-seeds@0.0.1 seed: `node bin/seed`
npm ERR! Exit status 1
...

When I try npm run-script seed -d "localhost/ease" I get this error.

npm run-script seed -d localhost/ease-dev
npm info it worked if it ends with ok
npm info using npm@1.4.3
npm info using node@v0.10.26
npm ERR! Error: ENOENT, open 'C:\Users\m089269\WebstormProjects\node-mongo-seeds\node_modules\seed\package.json'
...

Why is it looking for a package.json in node_modules\\seed? Seed is not even a dependency.

Answer 1

From the documentation :

npm supports the "scripts" member of the package.json script, for the following scripts:

• prepublish: Run BEFORE the package is published. (Also run on local npm install without any arguments.)
• prepare: Run both BEFORE the package is packed and published, on local npm install without any arguments, and when installing git dependencies (See below). This is run AFTER prepublish , but BEFORE prepublishOnly .
• prepublishOnly: Run BEFORE the package is prepared and packed, ONLY on npm publish .
• prepack: run BEFORE a tarball is packed (on npm pack , npm publish , and when installing git dependencies).

• postpack: Run AFTER the tarball has been generated and moved to its final destination.

• publish, postpublish: Run AFTER the package is published.

• preinstall: Run BEFORE the package is installed
• install, postinstall: Run AFTER the package is installed.
• preuninstall, uninstall: Run BEFORE the package is uninstalled.
• postuninstall: Run AFTER the package is uninstalled.
• preupdate: Run BEFORE the package is updated with the update command.
• update, postupdate: Run AFTER the package is updated with the update command.
• pretest, test, posttest: Run by the npm test command.
• prestop, stop, poststop: Run by the npm stop command.
• prestart, start, poststart: Run by the npm start command.
• prerestart, restart, postrestart: Run by the npm restart command. Note: npm restart will run the stop and start scripts if no restart script is provided.

Additionally, arbitrary scripts can be run by doing npm run-script <stage> <pkg> .

You can see the reason why your npm test script works is because npm test is a built-in command. You must use npm run-script if you want to execute a script that is not executed by a built-in npm command.

Answer 2

Custom scripts declared in the package.json can be ran with the npm run <your-script> form in your shell.

Try npm run seed or npm run test

Answer 3

To execute the custom scripts in package.json using below

npm run-script seed

or

npm run-script < custom script >

or you can use

npm run < custom script >
