在package.json scripts:中，我有
...
"prestart": "cd client && yarn build",
"start": "node server",
"heroku-postbuild": "cd client && yarn build"
},
在本地，我想在运行节点服务器之前引用"heroku-postbuild"中的"prestart"在子文件夹中构建Webpack：
...
"prestart": "\"yarn run heroku-postbuild\"",
"start": "node server",
"heroku-postbuild": "cd client && yarn build"
},
yarn start返回
yarn run v1.3.2
$ "yarn run heroku-postbuild"
/bin/sh: 1: yarn run heroku-postbuild: not found
error Command failed with exit code 127.

"heroku-postbuild"仅保留用于heroku吗？
