Question

突然buffer我们的项目中出现了这个问题。从它的来源来看，这很奇怪......

console.error:“此浏览器缺乏v5.x所需的类型化数组 (Uint8Array) 支持。如果需要旧版浏览器支持，请使用 v4.x。bufferbuffer ”

console.error: "This browser lacks typed array (Uint8Array) 
support which is required by `buffer` v5.x. 
Use `buffer` v4.x if you require old browser support."

更改为较旧的 git 分支和版本会在模拟器和物理设备上继续出现此问题。我们包含了不同的缓冲区版本。

• 尽管缓冲区被各种依赖项使用，但我们尝试过：yarn add buffer@4.9.1
• 我们rm -rf node_modules && rm yarn.lock && yarn在以前有效的分支机构中进行了尝试。

需要将react-native升级到更新的版本。然后这个错误就消失了。
