当 Expo 应用程序不断出现此错误时，如何创建它？

Question

尝试了每一个可能的步骤

• 重新安装了 Node、NPM、Expo 等。

使用 NVM 重新安装节点

\n

显然，我通过商店多次安装的节点出现了错误，因此我决定改用节点版本管理器。

\n

指示：

\n

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh\n

\n

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash\n

\n

source ~/.bashrc\n

\n

nvm list-remote\n

\n

nvm install v16.17.1\n

\n

是的，它有效：
