React Native EXPO初始化命令失败

Question

我想按照本教程（https://facebook.github.io/react-native/docs/getting-started.html）开始学习react-native。

我遵循了第一步，在命令行上遇到了一些问题：expo init AwesomeProject

这是日志：

PS C:\Users\ANTD\react_native> expo init AwesomeProject2
? Choose a template: blank
[09:06:11] Extracting project files...
Process exited with non-zero code: 2
ERROR: C:\Users\ANTD\.expo\starter-app-cache\blank-31.0.0.tar.gz

ERRORS:

[09:06:11] Set EXPO_DEBUG=true in your env to view the stack trace.

我在github页面和论坛上搜索，但未找到相关信息。我也尝试过这个：

deleted files in .expo folder
npm -g uninstall expo-cli --save
npm install -g expo-cli@latest

但是同样的问题。

blank-31.0.0.tar.gz文件为空，仅包含html标记。可能是问题，但我不知道该怎么办...

谢谢

这里同样的问题，对我来说似乎是网络问题。

我深入研究了expo-cli的源代码，找到了模板的下载链接：

"templatesv2": [
    {
      "description": "The Blank project template includes the minimum dependencies to run and an empty root component.",
      "iconUrl": "https://d306o6r76fnu7o.cloudfront.net/template_icon_blank.png",
      "id": "blank",
      "name": "Blank",
      "url": "https://d306o6r76fnu7o.cloudfront.net/blank-31.0.0.tar.gz",
      "version": "31.0.0"
    },
    {
      "description": "The Tab Navigation project template includes several example screens.",
      "iconUrl": "https://d306o6r76fnu7o.cloudfront.net/template_icon_tabs.png",
      "id": "tabs",
      "name": "Tab Navigation",
      "url": "https://d306o6r76fnu7o.cloudfront.net/tabs-31.0.0.tar.gz",
      "version": "31.0.0"
    }
  ],

所以我手动下载文件并解压，cd 到它并运行expo start......并且卡住了大约 20 分钟。

当我失去耐心并按Ctrl+C杀死这个进程后，我尝试了一下，npm run android它成功了！

后来我也尝试了一下npm start，似乎也有效。
