Created git commit.

Success! Created testapp-1 at E:\react_projects\testapp-1
Inside that directory, you can run several commands:

  npm start
    Starts the development server.

  npm run build
    Bundles the app into static files for production.

  npm test
    Starts the test runner.

  npm 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 testapp-1
  npm start

Happy hacking!

看起来您不在项目目录中。您的项目位于testapp-1文件夹中，只有在该文件夹中才能找到package.json。因此，从testapp-1文件夹中打开一个终端，然后运行

npm start

您需要执行的

cd testapp-1

。一旦进入

testapp-1

目录。npm启动。我想“我们建议您先键入：

cd testapp-1 npm启动

”这条说明没有足够的帮助？您忽略了将

cd

放入项目目录，并且键入了start命令，这是

npm start

与

apm start

的对比。投票以“不可复制或因打字错误”结束。干杯，祝你好运。
