我的项目 package.json 中有以下脚本部分:

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

如果我运行 $ npm test 我会得到:

>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

如果我运行 $ npm seed，我会得到:

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    list, ll, ln, login, ls, outdated, owner, pack, prefix,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

为什么它能识别我的 test 脚本而不是我的 seed 脚本？

编辑

当我尝试 npm run-script seed 时，我收到了这个错误，这是预期的，因为我没有传入 -d 参数:

$ 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
...

当我尝试 npm run-script seed -d "localhost/ease" 时，我收到此错误。

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'
...

为什么要在 node_modules\seed 中寻找 package.json？种子甚至不是依赖项。

最佳答案

来自 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>.

你可以看到你的 npm test 的原因脚本有效是因为 npm test是一个内置命令。您必须使用 npm run-script如果你想执行一个不是由内置 npm 命令执行的脚本。
