解决的问题

Vue 2 solves the problem of building interactive user interfaces with a reactive, component-based architecture that is incrementally adoptable. It fits in workflows where teams need a lightweight yet scalable framework for single-page applications, but for new work, Vue 3 is the recommended path.

部署现实

当前可用的安装信号是：npm install vue。这只能作为起点，正式使用前建议让 Codex 或 Claude 检查 README、环境变量、运行时版本和部署目标。

商业可用性

当前记录的许可证是 MIT。这是重要的商业使用信号，但仍应核验许可证全文、依赖许可证、模型/API 条款和商标限制。

能力上限

Vue 2's capability ceiling is defined by its mature ecosystem, including vue-router, vuex, and tooling like vue-cli, which support large-scale applications. Its strengths include a gentle learning curve, flexible integration, and strong documentation. However, it is no longer maintained, meaning no new features, updates, or security fixes, and it lacks modern improvements present in Vue 3 such as the Composition API and better TypeScript support.
