[英]In node package.json, invoke script from another script with extra parameter, in this case add mocha watcher
in node's package.json I would like to reuse a command that I already have in a 'script'. 在节点的package.json中,我想重用我在“脚本”中已经拥有的命令。
Here is the practical example 这是实际的例子
instead of (note the extra -w on the watch script): 而不是(请注意监视脚本上的额外-w ):
"scripts": {
"test" : "./node_modules/mocha/bin/mocha --compilers coffee:coffee-script/register --recursive -R list",
"watch": "./node_modules/mocha/bin/mocha --compilers coffee:coffee-script/register --recursive -R list -w",
}
I would like to have something like 我想吃点东西
"scripts": {
"test" : "./node_modules/mocha/bin/mocha --compilers coffee:coffee-script/register --recursive -R list",
"watch": "npm run script test" + "-w",
}
which doesn't work (can't do string concats in json), but you should get what I would like 这是行不通的(不能在json中做字符串concat),但是您应该得到我想要的
I know that npm scripts support: - & (parallel execution) - && (sequencial execution) 我知道npm脚本支持:-&(并行执行)-&&(顺序执行)
so maybe there is another option? 所以也许还有另一种选择?
This can be done in npm@2.1.17
. 可以在
npm@2.1.17
完成。 You don't specify your OS and the version of npm
that you are using, but unless you have done something to update it, you are probably running npm@1.4.28
which does not support the syntax below. 您没有指定您的操作系统和使用的
npm
版本,但是除非您进行了一些更新,否则您可能正在运行npm@1.4.28
,它不支持以下语法。
On Linux or OSX you can update npm with sudo npm install -g npm@latest
. 在Linux或OSX上,您可以使用
sudo npm install -g npm@latest
更新npm。 See https://github.com/npm/npm/wiki/Troubleshooting#try-the-latest-stable-version-of-npm for a guide to updating npm
on all platforms. 有关在所有平台上更新
npm
的指南,请参见https://github.com/npm/npm/wiki/Troubleshooting#try-the-latest-stable-version-of-npm 。
You should be able to do this by passing an additional argument to your script: 您应该可以通过向脚本传递一个附加参数来做到这一点:
"scripts": {
"test": "mocha --compilers coffee:coffee-script/register --recursive -R list",
"watch": "npm run test -- -w"
}
I verified this using the following, simplified package.json: 我使用以下简化的package.json进行了验证:
{
"scripts": { "a": "ls", "b": "npm run a -- -l" }
}
Output: 输出:
$ npm run a
> @ a /Users/smikes/src/github/foo
> ls
package.json
$ npm run b
> @ b /Users/smikes/src/github/foo
> npm run a -- -l
> @ a /Users/smikes/src/github/foo
> ls -l
