為什么 npm 我無法完成安裝？ 為什么它告訴節點和 npm 是無效命令？

Question

試圖運行一個 React 項目。 我已經安裝了最新的節點，並根據自述文件嘗試了舊版本。 我已經卸載了 Node，從 APPDATA/ROAMING 和 ProgramFiles 中清除了它的所有痕跡，然后重新安裝。 同事機器上有各種版本的Node和npm，可以在本地運行項目。 我檢查了我的環境變量並確保正確設置了 PATH 屬性。 我已經從 JSON 文件中刪除了這個特定的 package 並重試並看到類似的問題。 節點和 npm 安裝清晰。 有人遇到過這種情況或有嘗試的建議嗎？ 我已經為此工作了好幾天。 謝謝。

Answer 1

我會嘗試再次重新安裝 Node！

Answer 2

我曾經在它似乎安裝的地方安裝過它，但在執行命令時卻沒有。 就像你一樣。 即使重新安裝npm和node，結果還是一樣。 我重新啟動了計算機，這為我解決了問題。 相當蹩腳的解決方案，我花了一段時間才發現。

希望這對你也有幫助。
