package.json 中依赖部分中的“npm:”前缀是什么意思？

Question

I am wondering what does that mean:我想知道这是什么意思：

"dependencies": {
    "@mui/styled-engine": "npm:@mui/styled-engine-sc@5.3.0",
}

What is that npm: prefix? npm:前缀是什么？

Answer 1

this commit introduced aliasing to npm cli此提交将别名引入 npm cli

Answer 2

Probably telling npm where to get the package from (in this case npm): https://docs.npmjs.com/cli/v8/configuring-npm/package-json#dependencies可能告诉 npm 从哪里获取 package（在本例中为 npm）： https://docs.npmjs.com/cli/v8/configuring-npm/package-json#dependencies

There's also file: and git: as you can see.还有file:和git:如您所见。

Answer 3

I've used this code for many times:我已经多次使用此代码：

"dependencies": {
    "node-sass": "npm:sass@x.y.z",
}

It makes npm download sass instead of node-sass.它使 npm 下载 sass 而不是 node-sass。
