create-react-app安装过程中出现问题

Question

[我正在尝试学习如何使用React，但是我对create-react-app有问题：https://create-react-app.dev/docs/getting-started/

我在使用的安装过程中遇到问题

npx create-react-app my-app
cd my-app
npm start

按照本教程的建议。

我所做的只是npx create-react-app my-app，但从终端获得的错误是

我尝试寻找修复程序，但建议使用sudo chown -R $USER /usr/local/lib/node_modules

如何解决此问题？

Answer 1

这似乎是权限问题。您可以手动创建此目录并尝试重新运行它吗？用户/qube/.npm/_cacache/index-v5/4c/c4。

Answer 2

意识到您不应该在用户名/用户名目录中使用该命令，因为它会引起问题，因此请使用

npx create-react-app my-app
cd my-app
npm start

例如，在您的应用程序目录中，在您台式机的目录中
