調用 Node.js v10.15.3 項目時出現問題

Question

我正在加載一個 Node v10.15.3 版本的項目。 當我調用它時，一切都正確加載：

就在那時它一直在等待瀏覽器調用，但是當我從瀏覽器調用 web 時：

http://host_URL:8003/discovery/?vid=49HFMN:49HFMN_V2

拋出以下錯誤：

...
[Browsersync] Serving files from: primo-explore
custom/49HFMN_V2
undefined:1

並停止執行。

在此鏈接中，您可以找到我嘗試在 Node.js 中實施的項目，根目錄中的 package.json：

我該如何解決？ 有任何想法嗎？

非常感謝你。

PS 我沒有太多運行 Node JS 的經驗，有沒有免費課程或教程的建議來學習如何使用它和解決錯誤？

Answer 1

我通過卸載所有 node.js 並使用 NVM 版本控制重新安裝所有內容來解決它，這是我以前不知道的，讓我可以更好地控制所有內容，並讓我更輕松地解決安裝問題。

簡而言之，Node.js系統出現了無法解決的問題，無葯可救，只好走激進的路。

Answer 2

@Naschkopf primo-explore/custom 文件夾下沒有任何文件，請檢查安裝指南的第 9 點。 在你的指揮下

 gulp run --view 49HFMN_V2 

我無法在 repo 中找到 49HFMN_V2，它必須在 primo-explore/custom 下

通過從您的 Primo 后台下載視圖代碼文件或使用 primo-explore-package GitHub 存儲庫，在自定義 package 文件夾（“...primo-explore\custom”）中填充您的自定義 View package 文件夾，以啟動一個新的 package 文件夾。 （如果您已經定義了視圖 package 並將其加載到 BO - 確保下載它，否則您將看不到並且可能會覆蓋之前的更改。）
