asp.net - 如何在 Visual Studio 2017 中使用 NPM 并安装包？

Question

我有一个简单的 Visual Studio 解决方案，运行 ASP.NET Core v2 并构建一个 React 应用程序。

现在，我想使用 NPM 安装一个简单的组件。在这个特定的例子中，它可能是:

npm install --save react-bootstrap-typeahead

我希望这个包只在我的解决方案中工作，而不是在其他地方工作。

我的结果:

当我运行它时，我得到以下很好的错误，这显然是有道理的。如果 NPM 认为它可以在 'C:\Users\LarsHoldgaard\package.json' 找到我的项目文件，运气不好。正确的路径是 C:\Users\LarsHoldgaard\Documents\Github\Likvido.CreditRisk\Likvido.CreditRisk\Likvido.CreditRisk .

我的想法:

作为 控制台菜鸟 ，我想我只需要更改我当前的文件夹。但是如果我运行 dir ，我在正确的文件夹中，我可以看到我的package.json连同其他文件。

安装组件的正确方法是什么？

Answer 1

我认为最简单的方法是简单地使用 Visual Studio 提供的 UI。

在项目的根目录中创建 package.json (这样做，右键单击您的项目，添加项目并搜索 NPM 。您将找到 npm Configuration File ):

{
  "name": "SomeName",
  "version": "1.0.0",
  "private": true,
  "devDependencies": {
    "react-bootstrap-typeahead": "*"
  }
}

请注意 *适用于最新版本。不建议这样做。最好指定您想要的版本。您会注意到，您支持版本和包名称的智能。

每次更改 json 文件时，只需按 CTRL + S。Visual Studio 会自动调用 NPM 并恢复包。

对于如何使用命令行，其他人已经回答了。但作为一个命令行菜鸟，我更喜欢这种方式。
