VSTS轰炸NPM安装吗？

Question

我有一个类似的VSTS批处理脚本：

cd (my UI dir)
echo npm install...
npm install
echo ng build --output-path %1\ui
ng build --output-path %1\ui
echo npm run ng build --output-path %1\ui
npm run ng build --output-path %1\ui
echo All done.

但是，令人费解的是，我似乎无法超越npm安装线。我的输出类似于：

这里有些警告我很容易忽略，但是批处理文件被认为是“已成功执行”，并且继续运行...没有我构建的UI项目（这很重要！）

有人可以向我解释这是怎么回事，以及如何从VSTS CI任务构建UI项目吗？我不知道这是VSTS，NPM还是角度CLI的问题，但是这个愚蠢的简单事情完全阻止了我设置CI构建。

解决方案

正如@CeceDong所建议的，我使用了错误的任务来实现这一目标。

• 首先，我需要确保已安装正确版本的Node.js（对于Angular 6 CLI，版本为v8.9 +）。方便地，有一项任务可确保安装正确版本的Node。
• 第二，我需要在角度项目目录中调用npm命令来运行npm install。
• 最后，我需要在我的角度项目目录中运行命令行任务：npm run ng build。它不会接受常规的ng build命令。一旦完成这些步骤，它就会按预期运行。

Answer 1

您可以使用npm任务来运行npm install或npm custom来查看是否可以成功构建：
