react-native - React Native expo init 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，但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
C:\Users\ANTD\.expo\starter-app-cache\blank-31.0.0.tar.gz
Open ERROR: Can not open the file as [gzip] archive


ERRORS:

Process exited with non-zero code: 2

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

我在 github 页面和论坛上搜索过，但没有找到相关信息。
我也试过这个:

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

但同样的问题。

blank-31.0.0.tar.gz 文件是空的，只有 html 标签。
可能是问题，但我不知道该怎么办...

谢谢

同样的问题，对我来说似乎是网络问题。

我挖了expo-cli的源代码，找到模板的下载链接:

"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缩，cd 到其中并运行 expo start ...并被卡住了大约 20 分钟。

在我失去耐心并按 Ctrl+C 终止此进程后，我尝试了 npm run android它奏效了!

我也试过 npm start之后，它似乎也有效。
