Is there a way to pass command line arguments to an npm 'pre' script or to a script which runs multiple commands?
有没有办法将命令行参数传递给npm'pre'脚本或运行多个命令的脚本?
Assuming a simple script mySexyScript.js that just logs out the process.argv :
假设一个简单的脚本mySexyScript.js只是注销process.argv:
console.log(process.argv);
This works
With an npm script:
使用npm脚本:
...
"scripts": {
....
"sexyscript": "node mySexyScript.js"
....
}
...
running:
npm run sexyscript -- --foo=bar
the arguments are logged to the console as expected.
参数按预期记录到控制台。
'pre' script - This doesn't work
'pre'脚本 - 这不起作用
With an npm script:
使用npm脚本:
...
"scripts": {
....
"presexyscript": "node mySexyScript.js"
"sexyscript": "node mySuperSexyScript.js"
....
}
...
running:
npm run sexyscript -- --foo=bar
the arguments are not passed to mySexyScript and they are not logged
参数不会传递给mySexyScript,也不会记录它们
Multiple commands - This also doesn't work
多个命令 - 这也不起作用
With an npm script:
使用npm脚本:
...
"scripts": {
....
"sexyscript": "node mySexyScript.js && node mySuperSexyScript.js"
....
}
...
running:
npm run sexyscript -- --foo=bar
the arguments are not passed to mySexyScript and they are not logged
参数不会传递给mySexyScript,也不会记录它们

There is no way to pass args in the way that you are describing.
没有办法按照你描述的方式传递args。
Assuming a package.json:
假设一个package.json:
...
"scripts": {
....
"somescript": "node one.js && node two.js"
....
}
...
Running:
npm run somescript -- --foo=bar
basically just runs
基本上只是运行
node one.js && node two.js --foo=bar
on the default system shell (usually bash or cmd.exe).
在默认的系统shell(通常是bash或cmd.exe)上。
npm doesn't actually know anything about shell operators (i.e. &&), so it can't pass args to both scripts.
npm实际上并不了解shell运算符(即&&),因此它无法将args传递给两个脚本。
