问题描述

我有一个看起来像这样的package.json:

I have a package.json that looks similar to this:

"scripts": {
    "dev": "cross-env BABEL_ENV=client webpack --config webpack/client.development.js && yarn dev:stub-server | cross-env BABEL_ENV=server babel-node src/server/server.js",
    "dev:stub-server": "./node_modules/.bin/robohydra ./stubs/robohydra-config.json -p 3100"
}

我在代码中添加了一些逻辑,以根据命令行参数更改dev:stub-server的配置方式.因此,无论何时运行以下命令,我都会得到期望的结果:

I added some logic in the code to change the way the dev:stub-server is configured depending on a command line argument. So, whenever I run the following I get what I expect:

yarn dev:stub-server --results=4
$ ./node_modules/.bin/robohydra ./stubs/robohydra-config.json -p 3100 -- --results=4

如您所见,这些选项将转发到基础脚本,并且一切都会按预期进行.

As you can see, the options are forwarded to the underlying script and everything works as expected.

我的问题是我无法将--resultsyarn dev命令传播到dev:stub-server的正确位置.父脚本运行dev:stub-server,但是该参数最后被转发到基础脚本,如下所示:

My problem is that I cannot have the --results propagated from the yarn dev command to dev:stub-server in the correct position. The parent script runs dev:stub-server but the argument is forwarded to the underlying script at the end as follows:

yarn dev --results=2
$ cross-env BABEL_ENV=client webpack --config webpack/client.development.js && yarn dev:stub-server | cross-env BABEL_ENV=server babel-node src/server/server.js --results=2

是否可以通过以下方法使上述工作正常进行?

Is there a way to make the above work as follows instead?

yarn dev --results=2
$ cross-env BABEL_ENV=client webpack --config webpack/client.development.js && yarn dev:stub-server --results=2 | cross-env BABEL_ENV=server babel-node src/server/server.js

提前谢谢!

推荐答案

纱线的 仅支持将args附加到命令链的末尾,并且至少从2018年6月14日开始,没有任何方法可以覆盖它.

Yarn's run only supports appending your args to the end of the command chain, and at least as of date 2018-06-14, there isn't a way to override that.

过去我需要此功能时,我已经编写了自己的dev.js脚本,该脚本由我的package.json调用,并提取了参数变量.

When I've needed this in the past, I've cooked up my own dev.js script that was called by my package.json, and pulled args out environment variables.
