npm init -y install 的 package.json 错误答案

【问题标题】：package.json bug with npm init -y installnpm init -y install 的 package.json 错误
【发布时间】：2020-09-27 09:14:22
【问题描述】：

为了 sass 编译，我安装了 node.js，我现在还没有接触过任何 javascript，所以我为解决这个问题而经历的所有文档对我来说真的很复杂。因此，当我将 npm init -y 命令放入 VScode 终端时，它会安装 package.json 文件，该文件在第 5 行和第 6 行之间具有调试属性。

当我点击终端时显示的“调试”错误是这些......

"Error: no test specified" 
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! c@1.0.0 test: `echo "Error: no test specified" && exit 1`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the c@1.0.0 test script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm WARN Local package.json exists, but node_modules missing, did you mean to install?

【解决方案1】：

VScode 为您提供了一种运行“npm test”的快速方法，该方法完全按预期运行。您可以在“脚本”属性中指定要运行的命令。如您所见，有一个用于“测试”，它准确地输出那里写的内容。这就是“调试”的作用。您需要在那里挂钩一个真正的测试命令，以便调试执行任何有用的操作。

【解决方案2】：

调试内容是 npm run test 的输出，如果您只安装 package.json 以便您可以安装 sass 进行开发，则无需关心它。如果您希望能够通过 npm run test 运行测试，请更改第 7 行的键/值对的值以运行您的测试。

  "test": "someTestCommand.exe"

但同样，如果您只是为了获得 sass 编译而这样做，您可以放心地忽略它。
