【問題解決】ubuntu中gcc not found找不到gcc

Ubuntu中gcc not found找不到gcc。

Command 'gcc' not found, but can be installed with:
apt install gcc

嘗試輸入apt install gcc後出現很多代碼，然後提示失敗

E: Unable to fetch some archives, maybe run apt-get update or try with fix-missing?

根據提示輸入apt-get update 更新完成後再重新安裝gcc
輸入代碼gcc version查看gcc版本，就成功啦！

gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0
