'react-native' 不是内部或外部命令，也不是可运行的程序或批处理文件 [英] 'react-native' is not recognized as an internal or external command, operable program or batch file

问题描述

我最近开始使用 react-native.我使用 facebook 网站上的教程安装它，一两天内一切正常，直到出现此消息:

I recently started with react-native. I install it using the tutorial on the facebook site and everything works well for a day or two, until this message comes up:

'react-native' is not recognized as an internal or external command,
operable program or batch file.

除了卸载所有内容并重新开始外，什么都不起作用.环境还可以并且可以工作(npm、choco 等).我还尝试删除和添加 react-native 到环境变量，重新启动，在管理员模式下运行 cmd，但到目前为止还没有.我应该补充一点，我使用的是 Windows 10 64 位.

Nothing works except uninstalling everything and starting all over again. The environments are ok and work (npm, choco, etc.). I have also tried removing and adding react-native to environment variables, restarting, running cmd in administrator mode, but nothing so far. I should add that I use windows 10 64-bit.

推荐答案

我遇到了同样的问题并尝试了以下但没有奏效1) 将 npm 路径添加到我的环境变量中；系统和用户2) 重新安装 npm 和 react-native-cli

I had the same issue and tried the following but didnt work 1) Adding npm path to my Environment variables; both system and user 2) Re install npm and react-native-cli

两者都不适合我，我使用的是 Windows 10；

Both didn't work for me, im using Windows 10;

对我有用的解决方案是全局安装 react-native-cli您可以使用以下命令全局安装它:

Solution that worked for me is to install react-native-cli globally You can install it globally by using the below command:

npm install -g react-native-cli

希望能帮到你！干杯:)
