将日期传递给 package.json 脚本 [英] Passing date to package.json script

问题描述

我有一个要设置的部署脚本.我正在尝试将一个名为 DEPLOY_DATE 的环境变量设置为等于现在.

I have a deployment script I'm trying to set. I'm trying to set an environmental variable called DEPLOY_DATE equal to now.

"scripts": {
    "deploy": "kubectl set env deploy/api DEPLOY_DATE=\"$(date)\""
}

问题是这只是将 DEPLOY_DATE 设置为等于 $(date) 而不是实际日期.

The problem is this just sets DEPLOY_DATE equal to $(date) instead of the actual date.

package.json 脚本是否可以实际评估日期变量或任何变量?

Is there anyway package.json script can actually evaluate the date variable, or any variable?

推荐答案

我认为设置正确，请尝试以下方法验证:

I think it's correctly set, try the following to verify:

"deploy": "kubectl set env deploy/api DEPLOY_DATE=\"$(date)\"; echo $DEPLOY_DATE"

如果打印日期一切正常.我测试了:

If date is printed all is OK. I tested with :

"deploy": "export DEPLOY_DATE=\"$(date)\"; echo $DEPLOY_DATE"

当运行npm run deploy"时，我得到:

And when run "npm run deploy" I obtain:

> test@1.0.0 deploy /home/me/projects/test
> export DEPLOY_DATE="$(date)"; echo $DEPLOY_DATE
