当我运行npx创建反应应用程序我的应用程序时出错

Question

我已经尝试过这两个命令，并且得到了相同的错误。

npm clean cache --force
npx create-react-app client -timeout=120000


$ npx create-react-app client -timeout=120000

我刚刚在更新一个旧项目时也遇到了同样的问题。在我的案子中，解决的是：

如果使用yarn，则

yarn global remove create-react-app
yarn cache clean

如果使用npm，则

npm remove create-react-app
npx clear-npx-cache

另外，请确保目录中没有创建新React项目的文件夹，因为您可以得到另一个类似于以下内容的警告：

The directory . contains files that could conflict:

  <the file(s) name here>/

Either try using a new directory name, or remove the files listed above.

在那之后，npx create-react-app .跑得很顺利。

上述步骤解决了以下后续警告(版本可能有所不同)：

1. 全球预警

You are running "create-react-app" 4.0.3, which is behind the latest release (5.0.0).
We no longer support global installation of Create React App.

1. 焦油警告

tar@2.2.2: This version of tar is no longer supported, and will not receive security updates. Please upgrade asap.

甚至我也得到了同样的错误，然后看到你的问题，我关闭了所有的任务，并运行这个命令"npx创建-反应-应用程序我的应用程序“，它再次解决了！

Answer 3

我也有同样的问题，所以我在全球范围内卸载它，然后重新安装：-

create-react-app

• npm卸载create-react-app

• npm卸载-g

然后我用npx:-

• npx创建反应应用项目-app

告诉我这个对你有用吗？
