從上面的錯誤資訊我們來抓重點看就是第一行 verbose stack Error: Unsupported URL Type "npm:": npm:@elastic/[email protected]

Unsupported URL Type 這個錯誤。

錯誤原因和解決

出現這個錯誤的原因是你的 node 版本可能過低了。

你需要切換使用更高一點的 node 版本。

如果你對切換 node 的版本和 NPM 之間的關係有什麼不清楚的話，可以參考下面的內容：NPM 和 NVM

當你切換 node 版本完成後，再次嘗試安裝就應該能夠解決你的這個問題了。

 

 

當我們切換版本完成後再次進行安裝，就能夠成功了。
