以支持它。</p><p>Taskfile 文件的 <code>version:</code> 关键字接受语义化字符串， 所以 <code>2</code>, <code>2.0</code> 或 <code>2.0.0</code> 都可以。 如果使用版本号 <code>2.0</code>，那么 Task 就不会使用 <code>2.1</code> 的功能， 但如果使用版本号 <code>2</code>, 那么任意 <code>2.x.x</code> 版本中的功能都是可用的， 但 <code>3.0.0+</code> 的功能不可用。</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="版本-1">版本 1<a href="#版本-1" class="hash-link"
