使用expo安装NPM包失败

Question

我正在尝试使用expo下载@react-native-community/slider。这样做会失败

Expo版本: 4.12.10 NPM版本: lastest(8.1.2)

我读到过你应该在https://github.com/callstack/react-native-slider/issues/333上添加--遗留同级-dep

但是，您不能在expo中做到这一点。

Answer 1

先安装NPM包，然后使用expo命令：

npm i --save @react-native-community/slider --legacy-peer-deps
expo install @react-native-community/slider

看起来这对我很管用。
