1. 無(wú)法安裝vue-cli
在網(wǎng)上查的，是因?yàn)閛s版本過(guò)高的問(wèn)題。安裝 npm install -g @vue/cli時(shí)會(huì)出現(xiàn)這個(gè)問(wèn)題
npm WARN deprecated fsevents@1.2.9: One of your dependencies needs to upgrade to fsevents v2: 1) Proper nodejs v10+ support 2) No more fetching binaries from AWS, smaller package size

解決辦法：
在終端輸入這個(gè)命令
sudo chown -R $(whoami) /usr/local/*
然后再運(yùn)行npm install -g @vue/cli就可以正常安裝了。
2. 安裝vue-cli之后，發(fā)現(xiàn)終端并沒(méi)有vue
終端輸入vue，發(fā)現(xiàn)未找到，command not find:vue
這個(gè)問(wèn)題應(yīng)該是環(huán)境變量沒(méi)配置，配置一下環(huán)境變量
- 首先安裝一下vue-cli
sudo npm intall -g vue-cli
就算上面安裝了@vue/cli，這個(gè)vue-cli也是要安裝的
安裝后是這樣的
安裝vue-cli
- 繼續(xù)在終端輸入
export PATH="$PATH:/usr/local/bin/vue"，$PATH:后面這個(gè)就是上圖中標(biāo)紅的 - 到此vue就可以正常使用了
