Question

您好我正在寻找更新我的Angular应用程序，该应用程序目前正在Angular ng-version 2.4.0 rc.1上更新为新的角度4/5。我的问题是我应该将哪个版本迁移到角度版本4或5？这是稳定版本，将完全支持。我正在寻找改变，以使我的应用程序运行更快，更健壮，主要是提高性能。我在我的应用程序中使用highcharts和kendo网格库。我想建议移动到哪个版本和哪个指南跟进，这样我就不会陷入混乱和修复错误。我的应用程序也说 - 您的全局Angular CLI版本（1.4.9）大于您的本地版本版本（1.0.0-rc.0）。使用本地Angular CLI版本。所以我也要升级cli版本吗？下面是我的package.json文件 -

请查看Angular update tool以获取有关可能问题的帮助。

当您从命令行使用angular cli时，它使用全局版本。当它从您的项目脚本中使用时，它使用本地版本。尽可能在全球和本地保持最新状态。在为新应用程序创建新shell之前更新CLI，然后将package.json，app文件夹和其他依赖项复制到新shell。

祝你好运：）
