最近電腦重裝系統(tǒng)后運行 npm run dev 正常運行，npm run build 打包文件模暗，提示如下錯誤：

家里的電腦上可以正常運行，考慮是缺少了什么文件，但不知道是哪個文件讹蘑，網(wǎng)上搜索相關(guān)問題，最后看到一個?
'NODE_ENV' ????????????????????????е??????????????????
報錯筑舅，于是回頭看我那個
?'webpack' ????????????????????????е?????????????????
之前一直沒注意到這個座慰，這就是缺少的文件，原來我在項目本地安裝了webpack豁翎，重裝系統(tǒng)后未全局安裝角骤。
先全局安裝webpack隅忿，
$ npm install webpack -g
