NPM安裝在Windows中出錯

Question

我的nodejs最近被破壞並重新安裝。 現在，我在安裝npm依賴項時遇到此錯誤。 我錯過了什么？

C:\Projects\xyz>npm i
/
> bufferutil@1.2.1 install C:\Projects\basic-vplex-sizer-ui\node_modules\bufferutil
> node-gyp rebuild


C:\Projects\basic-vplex-sizer-ui\node_modules\bufferutil>if not defined npm_config_node_gyp (node "C:\Users\ham13\AppData\Roaming\nvm\v4.4.3\node_modules\npm\bin\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild )  else (node "" rebuild )

如果Node.js版本已更改，請檢查node -v然后您必須執行npm rebuild，如果仍然出現錯誤，則刪除node_modules文件夾並執行npm install 。

希望有效。
