【问题描述】：
我是 React Native 的新手，在处理一个旧项目时遇到此错误，在过去的几个小时内无法解决，有人请帮忙吗？
JavaScript 版本：0.50.4 原生版本：0.62.2
确保您已重建本机代码。如果问题仍然存在，请尝试使用
watchman watch-del-all && react-native start --reset-cache清除 Watchman 和打包程序缓存。
这就是我的 package.json 的样子

【问题讨论】：
-
已经 4 天了。我仍在为这个错误而苦苦挣扎。
-
您有一个旧的 Metro 捆绑器实例正在运行。关闭它并再次运行
react-native android或react-native ios。如果找不到，请重新启动计算机。 -
重启电脑试了很多次。你能解释一下吗？
-
错误信息表示项目使用的是React Native 0.50.4版本，但手机或模拟器使用的是0.62.2版本。如果您使用的是 react-native-cli 的全局实例，则它的版本可能与项目版本不匹配。
-
感谢您的回复@GuyIncognito。我已经更新了添加
package.json的问题我已经将我的react-native 版本从0.62.2降级为^0.61.4，正如您在我的package.json 文件中看到的那样。我如何更新我的 Java Script 版本以更新以满足我的 react-native 版本的匹配。
