使用@vue/cli4.2.3 create初始化一個(gè)項(xiàng)目后，運(yùn)行命令一直報(bào)如下錯(cuò)誤，提示ansi-sytles找不到
解決過(guò)程：
1、以為是缺少提示中的包，直接按照提示安裝ansi-sytles，無(wú)果。
事情遠(yuǎn)沒(méi)有想的這么簡(jiǎn)單
2、rm -rf node_modules 再 npm install,無(wú)果
3、rm -rf node_modules 再npm cache clean -f清空緩存，再 npm install,無(wú)果
4、懷疑是自己電腦環(huán)境，找同事初始化了一個(gè)項(xiàng)目打包給我，運(yùn)行npm run serve,還是同樣的報(bào)錯(cuò)
5、有點(diǎn)絕望了，看到網(wǎng)上說(shuō)@vue-cli4會(huì)自己升級(jí)sass-loader,于是升級(jí)了sass-loader，但是會(huì)提示node-sass安裝不上，（原因是node-sass要從github上下載包，國(guó)內(nèi)網(wǎng)絡(luò)環(huán)境導(dǎo)致經(jīng)常安裝不上）想辦法裝上了node-sass，依舊無(wú)果~

6、嘗試將@vue/cli降級(jí)后再初始化出來(lái)一個(gè)項(xiàng)目，成功！
以下是前五步出錯(cuò)階段一直存在的報(bào)錯(cuò)提示：
