The interface is not displayed in the system language （我的Vue Cli Ui界面变成了英文）

[ideacco]

Version

3.1.1

Node and OS info

node v8.12.0 / npm v6.4.1 / MAC OS 10.14

Steps to reproduce

在命令行中输入 ：vue ui
Enter on the command line：vue ui

What is expected?

当我打开Vue-Cli 的UI 界面时，显示中文界面
When I open the UI interface of Vue-Cli, the Chinese interface is displayed.

What is actually happening?

显示为英文
Displayed in English

---

我用 VUE-cli 3.0.5的时候显示的是中文的，升级到了3.1.1后显示成了英文（升级过程中，删除了之前版本的VUE），且不知道在哪里可以调整配置文件。

When I use VUE-cli 3.0.5, it is displayed in Chinese. After upgrading to 3.1.1, it is displayed in English (in the upgrade process, the previous version of VUE is deleted), and I don't know where to adjust the configuration file.

• try https://unpkg.com/vue-cli-locales@3.0.5/locales/zh-CN.json, Cannot find "/locales/zh-CN.json" in vue-cli-locales@3.0.5❌

• try https://unpkg.com/vue-cli-locales@3.0.5/locales/zh.json, GOOD☑️

@ideacco check you cli-ui's console and find answer.

It's network error when fetching https://unpkg.com/vue-cli-locales@3.0.5/locales/zh.json

maybe no network, dns error or firewall problem. Anyway, this can be improve with local locale..

Thanks, the problem is solved. Now that Chinese is normal, I upgraded vue cli from 3.1.1 to 3.1.3. The magic happened and the problem was fixed automatically. Although I don't know what happened.
