安装react本机元素时出现NPM错误

Question

我想为我的应用程序安装react-native-elements，但在cmd提示符中输入install命令后，它会给出以下错误：

npm ERR! Unexpected end of JSON input while parsing near '...webpack-loader":"^3.3'
npm ERR! A complete log of this run can be found in:

所有其他库都已成功安装。只有react-native-elements出现错误。

Answer 1

尝试安装旧版本的react本机元素。

我通过使用npm install react-native-elements@3.0.0安装3.0.0版本解决了这个问题。

通过只执行npm install react-native-elements(没有固定版本(，npm试图安装反作用原生元素的3.3.2版本。

另一种选择是使用--legacy-peer-deps标志：

npm install --legacy-peer-deps

或

npm install react-native-elements --legacy-peer-deps

Answer 2

首先，尝试

npm cache clean --force

然后安装react原生元素

npm install react-native-elements
