第一次安装expo，初始化后立即报错

Question

我正在按照此处包含的步骤进行操作 https://facebook.github.io/react-native/docs/getting-started

我已经安装了新的 npm 副本，甚至完成了 npm update 命令

然后我跑了npm install -g expo-cli

这给出了一大堆关于未安装 linux 软件包但我正在运行 Windows 10 Home 64 位的警告，所以没有问题

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: @expo/ngrok-bin-darwin-ia32@2.2.8 (node_modules\expo-cli\node_modules\@expo\ngrok-bin-darwin-ia32):
    npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for @expo/ngrok-bin-darwin-ia32@2.2.8: wanted {"os":"darwin","arch":"ia32"} (current: {"os":"win32","arch":"x64"})

然后我输入expo init HelloWorld 并得到以下错误

C:\Users\####\AppData\Roaming\npm\node_modules\expo-cli\node_modules\formidable\lib\incoming_form.js:1

我不知道为什么。它是一个全新的安装，我是否错过了安装？

使用npm install formidable，然后将生成的文件夹复制到expo 拥有formidable 副本的位置，从而解决了问题。
