使用 lerna 将自定义参数发送到 npm(纱线)脚本 [英] sending custom arguments to npm (yarn) scripts with lerna

问题描述

我在尝试使用 lerna 将参数传递给 npm 脚本时遇到问题.

I have an issue when trying to pass arguments to an npm script with lerna.

我有一个节点脚本，我想在工作区中的每个包中运行它.lerna 文档建议如下:

I have a node script that I want to run inside each package in the workspace. lerna docs suggests the following:

{
    "scripts": {
      "my-script": "lerna exec -- node \\$LERNA_ROOT_PATH/scripts/my-script.js"
    }
}

现在，如果我在根目录中运行 yarn run my-script 它将运行工作区中每个包内的脚本.

so now, if I run in the root yarn run my-script it will run the script inside each package in the workspace.

有时，我需要将执行范围限定为特定的包.所以从命令行运行这个显然有效:lerna exec --scope somepackage -- node \$LERNA_ROOT_PATH/scripts/create-common-scripts.js.

Sometimes, I need to scope the execution to a specific package. So running this from command line obviously works: lerna exec --scope somepackage -- node \$LERNA_ROOT_PATH/scripts/create-common-scripts.js.

我的问题:如何将 npm 脚本与 lerna 范围参数连接起来.这不起作用:yarn run my-script --scope somepackage，因为它将参数设置为命令的末尾:lerna exec -- node \\$LERNA_ROOT_PATH/scripts/my-script.js --scope somepackage.

My question: how can I connect the npm script with the lerna scope argument. this is not working: yarn run my-script --scope somepackage, as it sets the argument to the end of the command: lerna exec -- node \\$LERNA_ROOT_PATH/scripts/my-script.js --scope somepackage.

谢谢！

推荐答案

使用 Lerna 时命令经常嵌套.意思是一个命令会调用另一个命令，等等.例如下面的命令:

When using Lerna commands are often nested. Meaning one command will call anther command, etc. For example the following command:

npm run release (in monorepo root) [1] > lerna run release [2] > npm run release (in package) [3] > release-it [4]

在 shell 中，参数可以在运行时使用双破折号 (--) 传递给嵌套命令.它标志着参数(选项)列表的结束.-- 之后的任何参数都将被提升到下一个命令.这将适用于嵌套多级深度的命令，您所要做的就是添加 -- 的数量以匹配您要传递给它们的命令的级别.

In a shell arguments can be passed to nested commands at runtime using a double dash (--). It marks the end of the parameter (option) list. Any parameter after the -- will be hoisted to the next command. This will work with commands nested multiple levels deep, all you have to do is add the number of -- to match the level of the command you want to pass them to.

记住前面的例子，下面的命令:

With the previous example in mind, the following command:

$ npm run release -- --stream -- -- --dry-run --no-git.requireCleanWorkingDir

将参数提升到:

1. npm run release
2. lerna run release --stream
3. npm run release
4. release-it --dry-run --no-git.requireCleanWorkingDir
