Visual Studio代码和口吃

Question

我对Visual Studio Code和gulp有疑问。

我正在将打字稿版本3.7.2与最新版本的Visual Studio代码一起使用。当我运行gulp build时，得到以下输出：

[12:03:36] Starting gulp
[12:03:36] Starting 'build'...
[12:03:36] Starting subtask 'configure-sp-build-rig'...
[12:03:36] Finished subtask 'configure-sp-build-rig' after 6.42 ms
[12:03:36] Starting subtask 'pre-copy'...
[12:03:36] Finished subtask 'pre-copy' after 55 ms
[12:03:36] Starting subtask 'copy-static-assets'...
[12:03:36] Starting subtask 'sass'...
[12:03:37] Finished subtask 'sass' after 1.38 s
[12:03:37] Starting subtask 'tslint'...
[12:03:39] [tslint] tslint version: 5.12.1
[12:03:39] Starting subtask 'tsc'...
[12:03:39] [tsc] typescript version: 2.9.2
[12:03:40] Finished subtask 'copy-static-assets' after 4.46 s
[12:03:48] Finished subtask 'tslint' after 10 s
[12:03:49] Finished subtask 'tsc' after 10 s
[12:03:49] Starting subtask 'post-copy'...
[12:03:49] Finished subtask 'post-copy' after 428 μs
[12:03:49] Finished 'build' after 14 s
[12:03:50] ==================[ Finished ]==================

我的问题特别是关于1行：

[12:03:39] [tsc] typescript version: 2.9.2

为什么我安装了3.7.2后使用打字稿2.9.2版？有办法改变吗？

编辑：

完整gulpfile.js

'use strict';

const gulp = require('gulp');
const build = require('@microsoft/sp-build-web');

build.addSuppression(`Warning - [sass] The local CSS class 'ms-Grid' is not camelCase and will not be type-safe.`);

// Taken from: https://blog.mastykarz.nl/correctly-reference-images-sharepoint-framework-solutions/
build.configureWebpack.mergeConfig({
  additionalConfiguration: generatedConfiguration => {
    if (build.getConfig().production) {

      var basePath = build.writeManifests.taskConfig.cdnBasePath;
      if (!basePath.endsWith('/')) {
        basePath += '/';
      }

      generatedConfiguration.output.publicPath = basePath;
    }
    else
    {
      generatedConfiguration.output.publicPath = '/dist/';
    }

    return generatedConfiguration;
  },
});

build.initialize(gulp);

我正在用口水3.9.1。我尝试升级，但遇到问题，因此不得不降级。

[我发现了一篇引导我朝正确方向HERE的文章。现在我看到以下内容：

[tsc] typescript version: 3.3.4000

仍未使用3.7.2，但我想它已经足够了。希望这对其他人有帮助...
