設置新項目時出錯 react-native

Question

我是 React-native 的新手。我正在嘗試設置一個沒有 expo 的 react-native 項目並使用 Typescript 但出了點問題，我不明白是什么導致了錯誤。

這是我運行命令時的終端內容：npx react-native init MyApp --template react-native-template-typescript

您將需要具有根訪問權限才能執行此操作。 如果您還不是管理用戶，請以管理員身份登錄。 然后使用“sudo”更改權限：

sudo chmod go -w /usr/local/bin

顯然，這將意味着你不能再在 /usr/local/bin 中安裝材料，除非通過“sudo”，但你可能不應該這樣做。
