發現很早就有人碰到這個問題: npm does not work with Virtualbox shared folders. #992

似乎可以用 npm install –no-bin-links 的方式來解決

但我覺得很麻煩, 想說乾脆試試 yarn, 照著官網說明步驟安裝, 結果測試的時候改出現 Cannot find module 錯誤, 想說用 yarn info 明明就看的到那套件, 怎麼會呼叫不到, 後來看到這發文才知道似乎是 yarn 的 Plug’n’Play 特性, 不能使用 node hello.js, 而是要使用 yarn node hello.js 才能正常抓到安裝的套件, 儘管不太懂其中原理, 但能跑比較重要, 就先這樣吧.
