[Linux] 安裝 pylint 時出現 No module named pbr.pbr_json 錯誤
今天在 CentOS 7 上安裝 pylint 時,莫名地遇到了沒碰過的問題,
說 ImportError: No module named pbr.pbr_json:

查了一下,似乎 pbr 套件需要更新 (但不知道為什麼以前不會有問題)…
先安裝 pip:
sudo yum -y install epel-release sudo yum -y install python-pip
再用 pip 更新 pbr 套件:
sudo pip install -U pbr
再次安裝 pylint 就沒遇到問題了~
