我正在尝试在我的项目中安装create-react-app，但是生成了没有启动脚本的package.json，并且我收到一条错误消息“未提供模板。这可能是因为您使用的是过时的版本创建反应应用程序。请注意，不再支持在全球范围内安装create-react-app。”正如有关此问题的其他问题所建议的那样，这是我已经尝试过的方法：npm uninstall -g create-react-app，which create-react-app然后是rm -rf [the path that was listed]（现在当我输入which create-react-app时会说which: no create-react-app in .....，然后重新启动计算机。
我不知道还能尝试什么。任何帮助表示赞赏。
这是我的完整错误消息/尝试运行create-react-app时得到的信息：

A template was not provided. This is likely because you're using an outdated version of create-react-app.
Please note that global installs of create-react-app are no longer supported.
所以最好的办法是使用create-react-app或npm uninstall create-react-app -g全局删除yarn global remove create-react-app，因为这很可能是您看到此错误消息的原因：
This is likely because you're using an outdated version of create-react-app. Please note that global installs of create-react-app are no longer supported.
一旦删除它，请注意，您无需全局安装create-react-app即可初始化新项目，建议您至少使用npx及以上版本附带的node 5.2打包运行器工具。因此，npx基本上将允许您运行软件包而无需安装它，所以就您的情况而言create-react-app。
因此，要创建一个新项目，只需输入：npx create-react-app myapp，这将初始化您的react应用。
发生这种情况的原因是因为您在重新启动计算机后运行了npm update -g create-react-app。再次卸载，然后使用npx create-react-app name-of-my-app
