紗線構建不創建構建文件夾

Question

我正在嘗試運行yarn build但命令失敗。 誰能幫我解決這個問題？ 使用的Node版本是v14.1.0，Yarn版本是1.22.19。 yarn start命令有效，但build命令無效。

Answer 1

yarn build 命令沒有創建構建文件夾的可能原因有幾個：

package.json 文件中的構建腳本可能配置不正確。 確保構建腳本指向項目的正確構建命令。

構建過程中可能發生錯誤，導致無法創建構建文件夾。 要解決此問題，您可以嘗試使用 --verbose 標志運行構建命令，這將打印出有關構建過程的詳細信息。

可能存在阻止創建構建文件夾的權限問題。 確保您擁有在當前目錄中創建新文件夾的必要權限。

build 文件夾可能已經存在，但它正在被 yarn build 命令覆蓋。 在這種情況下，您可以嘗試在運行構建命令之前刪除現有的構建文件夾。

您的項目依賴項可能存在問題。 確保安裝了所有必需的依賴項，並且項目代碼中沒有錯誤。

如果這些建議都沒有幫助，您可能需要提供有關您的項目和構建過程的更多信息，以便進一步解決問題。

Answer 2

當我嘗試npx serve -s build命令時它起作用了。 可能有人會在將來找到這個幫助

Answer 3
