【问题描述】：

由于兼容性原因，我需要使用 Ionic 4 而不是 5。如何初始化一个新的 ionic 4 项目？

根据Ionic CLI docs

Use the --type option to start projects using older versions of Ionic.

但是这样做并没有帮助。

HP:project user$ ionic start --list

【问题讨论】：

不是一个好主意，但您可以降级 CLI 以创建项目并再次升级 CLi。

For some reason, making the command all together like this: 
Ionic start myProject tabs --type=angular (which is ionic 4),  doesn't work, it show some errors like this: [ERROR] Network connectivity error occurred, are you offline? which is already been reported to the ionic team yesterday https://github.com/ionic-team/ionic/issues/20795,
