It's just a check as of NPM v1.2.20, they report this as a warning. 这只是NPM v1.2.20的检查，他们将此报告为警告。

However, don't worry, there are sooooooo many packages which still don't have the repository field in their package.json . 不过，不用担心，有仍然没有sooooooo许多包repository在自己的领域package.json 。 The field is used for informational purposes. 该字段用于提供信息。

In the case you're a package author, put the repository in your package.json , like this: 如果您是包作者，请将repository放在package.json ，如下所示：

"repository": {
  "type": "git",
  "url": "git://github.com/username/repository.git"
}

Read more about the repository field, and see the logged bug for further details. 阅读有关repository字段的更多repository ，并查看记录的错误以获取更多详细信息

Additionally, as originally reported by @dan_nl , you can set private key in your package.json . 此外， 正如@dan_nl最初报告的那样 ，您可以在package.json设置private 。
This will not only stop you from accidentally running npm publish in your app, but will also stop NPM from printing warnings regarding package.json problems. 这不仅会阻止您在应用程序中意外运行npm publish ，还会阻止NPM打印有关package.json问题的警告。

{
  "name": "my-super-amazing-app",
  "version": "1.0.0",
  "private": true
}

If you are getting this from your own package.json , just add the repository field to it. 如果您从自己的package.json获取此信息，只需将repository字段添加到其中即可。 (use the link to your actual repository): （使用指向实际存储库的链接）：

"repository" : { 
   "type" : "git",
   "url" : "https://github.com/npm/npm.git"
 }

you can also mark the application as private if you don't plan to put it in an actual repository. 如果您不打算将应用程序放在实际的存储库中，也可以将该应用程序标记为私有。

{
  "name": "my-application",
  "version": "0.0.1",
  "private": true
}

As dan_nl stated, you can add a private fake repository in package.json. 正如dan_nl所述，您可以在package.json中添加私有伪存储库。 You don't even need name and version for it: 你甚至不需要它的名称和版本：

{
  ...,
  "repository": {
    "private": true
  }
}

Update: This feature is undocumented and might not work. 更新：此功能未记录，可能无法正常工作。 Choose the following option. 选择以下选项。

Better still: Set the private flag directly. 更好的是：直接设置private标志。 This way npm doesn't ask for a README file either: 这样，npm也不会要求README文件：

{
  "name": ...,
  "description": ...,
  "version": ...,
  "private": true
}
