我现在很茫然。作为一种业余爱好，我正在关注Udemy视频指南，以使用react-native创建应用程序。我的教练随便运行命令npm run exit，一切对他都正常，没有错误。在该行的结尾，我收到了（据我发现）众所周知的错误
The batch file cannot be found.
npm ERR! code ELIFECYCLE

我在几页上读到，更改后的文件应提交给git或类似的文件。但是由于我的老师没有这样做，所以我认为他没有安装git，所以我从计算机中删除了它。
不仅在我退出“研究”应用程序时显示此错误消息，而且在我刚刚创建应用程序并立即弹出它时也会显示该错误消息。

Success! Created testapp2 at C:\Users\Mark\testapp2
Inside that directory, you can run several commands:
yarn start
Starts the development server so you can open your app in the Expo
app on your phone.
yarn run ios
(Mac only, requires Xcode)
Starts the development server and loads your app in an iOS simulator.
yarn run android
(Requires Android build tools)
Starts the development server and loads your app on a connected Android
device or emulator.
yarn test
Starts the test runner.
yarn run eject
Removes this tool and copies build dependencies, configuration files
and scripts into the app directory. If you do this, you can’t go back!
We suggest that you begin by typing:
cd testapp2
yarn start
Happy hacking!

> react-native-scripts eject
We didn't find any uses of the Expo SDK in your project, so you should be fine to eject to
"Plain" React Native. (This check isn't very sophisticated, though.)
We strongly recommend that you read this document before you proceed:
https://github.com/react-community/create-react-native-app/blob/master/EJECTING.md
Ejecting is permanent! Please be careful with your selection.
? How would you like to eject from create-react-native-app? React Native: I'd like a regular React Native project.
We have a couple of questions to ask you about how you'd like to name your app:
? What should your app appear as on a user's home screen? testpp
? What should your Android Studio and Xcode projects be called? testapp
Writing your selections to app.json...
Wrote to app.json, please update it manually in the future.

Updating your yarn scripts in package.json...
Your package.json is up to date!
Adding entry point...
Added new entry points!
Note that using `yarn start` will now require you to run Xcode and/or
Android Studio to build the native code for your project.

由于我对此还很陌生，还不知道如何正确进行； 1）如果我没有安装git，怎么仍然会产生此错误？ 2）我仍然需要提交更改吗？如果是这样，我该如何正确执行？ 3）创建安装了Yarn的应用程序时显示的警告消息可以安全地忽略吗？如果未安装Yarn，则不会显示这么多警告消息。
谢谢！

更新您的npm：
npm install -g npm
