无法解决'反应导航'

Question

当我安装并尝试使用react-navigation(从'react-navigation'导入{StackNavigator};)时,我尝试使用react-native并获得以下错误.

错误

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

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

  "_args": [
    [

        "raw": "react-navigation@0.0.0",

有人可以帮我解决这个问题.提前致谢.

Answer 1

您必须停止节点服务器并再次启动它.

这样做:

sudo lsof -n -i4TCP:8081 | grep LISTEN

它将侦听在端口8081上运行的服务.默认情况下,在其上运行反应本机服务器.然后,执行以下命令以终止服务器进程.

kill -9 <cma process id>

最后,再次运行您的项目

react-native run-ios 

在项目文件夹上

React导航仍处于beta中。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
