没有调用npm package.json脚本 [英] npm package.json scripts not being called

问题描述

我的项目package.json中有以下脚本部分：

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

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

如果我运行 $ npm test 我得到这个：

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

如果我运行 $ npm seed ，我明白了：

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    list, ll, ln, login, ls, outdated, owner, pack, prefix,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

为什么它会识别我的测试脚本而不是我的种子脚本？

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

编辑

当我尝试 npm run-script seed 我收到此错误，这是因为我没有传入 -d param：

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
...

当我尝试 npm run -script seed -dlocalhost / ease我收到此错误。

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'
...

为什么在node_modules \ seed中寻找一个package.json？种子甚至不是依赖。

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

推荐答案

来自文档：

npm支持package.json的scripts成员脚本，用于以下脚本：

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

• prepublish：在发布包之前运行。 （也可以在没有任何参数的本地 npm install 上运行。）


• 发布，postpublish：在程序包发布后运行。


• 预安装：在安装软件包之前运行


• 安装，postinstall：安装软件包后运行。


• preuninstall ，卸载：在卸载软件包之前运行。


• postuninstall：在卸载软件包后运行。


• preupdate：在更新软件包之前运行更新命令。


• 更新，postupdate：使用更新命令更新软件包后运行。


• pretest，test，posttest：由 npm test 命令。


• prestop，stop，poststop：由 npm stop 命令。


• 预启动，启动，poststart：由 npm start 命令运行。


• prerestart，restart，postrestart：由 npm restart 命令运行。注意：如果没有提供 restart 脚本， npm restart 将运行停止并启动脚本。

• prepublish: Run BEFORE the package is published. (Also run on local npm install without any arguments.)
• 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.

此外，可以通过执行 npm run-script< stage>来运行任意脚本。 < pkg> 。

您可以看到 npm测试的原因脚本的工作原理是因为 npm test 是一个内置命令。如果要执行未由内置npm命令执行的脚本，则必须使用 npm run-script 。

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.
