无法解析 'react-navigation'

Question

当我安装并尝试使用 react-navigation（从 'react-navigation' 导入 {StackNavigator}；）时，我正在尝试 react-native 并遇到以下错误。

Error

我使用以下命令安装 "react-navigation"：npm install --save react-navigation

在运行上面的命令中，我在 node_modules 文件夹下得到了 'react-navigation' 文件夹，其中只有一个文件 (package.json)。以下是文件的内容：

谁能帮我解决这个问题。提前致谢。

Answer 1

您必须停止您的节点服务器并重新启动它。

去做：

sudo lsof -n -i4TCP:8081 | grep LISTEN

它将侦听端口 8081 上运行ning 的服务。默认情况下，在其上响应本机服务器运行s。然后，执行下面的命令杀死服务器进程。

kill -9 <cma process id>

最后，运行您的项目再次

react-native run-ios

在项目文件夹中

Answer 2

React 导航仍处于测试阶段。当我使用命令时它对我有用：

npm install --save react-navigation@1.0.0-beta.7

这是最新版本。 https://github.com/react-community/react-navigation/releases

Answer 3

我无法安装 react-native，尝试了互联网上的所有方法。使用 Yarn 而不是 npm 解决了问题。

Answer 4

尝试安装 react-navigation 堆栈，npm i react-navigation-stack。然后import {createStackNavigator} from 'react-navigation-stack'

停止服务器并再次运行您的项目。
