Question

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

在我使用的安装过程中遇到了问题

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

如本教程中所建议。

我所做的只是npx create-react-app my-app，但是我从终端收到的错误是

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User / username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

在您的应用程序目录中，例如在您台式机的目录中
