javascript - What to do if cross-env doesn't work?

Question

The scripts statements in package.json are as follows

"test": "cross-env NODE_ENV=dev && node test.js"

test.js has only one sentence console.log(process.env.NODE_ENV)

But the result shows undefined

Why?

Answer 1

Ask and answer your own question, the reason is that there cannot be anything in the middle&&，&&This will divide the two environments before and after, resulting in the environment of the latter statement not having NODE_ENV

Answer 2

NODE_ENV=dev这里不能有空格
"test": "cross-env NODE_ENV=dev&& node test.js"
