expo init <项目名称=“”>引发npm错误（Windows操作系统）

Question

刚从expo和React-Native以及我运行时开始

expo init ProjectName

我收到一条错误消息：

Unexpected end of JSON input while parsing near '...,"version":"7.0.0-bet'
Process exited with non-zero code: 1
Set EXPO_DEBUG=true in your env to view the stack trace.

当我在环境中添加所说的内容（在Windows上使用set EXPO_DEBUG=true）时，出现以下错误：

Error: Process exited with non-zero code: 1 at ChildProcess.child.on (C:\Users\mohit\AppData\Roaming\npm\node_modules\expo-cli\node_modules\@expo\spawn-async\build\spawnAsync.js:39:21) at ChildProcess.emit (events.js:182:13) at ChildProcess.cp.emit (C:\Users\mohit\AppData\Roaming\npm\node_modules\expo-cli\node_modules\cross-spawn\lib\enoent.js:40:29) at maybeClose (internal/child_process.js:962:16) at Process.ChildProcess._handle.onexit (internal/child_process.js:251:5)

 这与“生成异步”有关。在创建节点服务器时，我也早些时候遇到了“ spawn”问题……但是我在那里解决了，然后改用“ exec”。试图在博览会论坛上甚至在本机问题中找到它，但找不到解决方案。有人可以建议些什么吗？是仅一些“ Windows”内容还是与npm版本相关的内容？
P.S：我还运行了create-react-native-app ProjectName，并再次收到关于JSON输入结束的类似错误！

Answer 1

现在我知道这可能是问题所在，可能只是个小问题：

• 请将node和npm更新到最新版本，并init在另一个目录中再次投影。

Answer 2

• You'll need to have Node.js (version 10 or newer) installed on your computer. Download the latest version of Node.js.
• Additionally, you'll need Git to create new projects with Expo CLI. You can download Git from here.

Make sure that you have installed these two things in your device.

Go to doc for expo installation

Answer 3

就我而言。确保您已安装yarn并更新Tour android studio软件包，以使其正常工作
