1.開啟Pycharm

3. 開啟命令列視窗，編輯環境檔案~/.bash_profile
   happy:~ happ$ vi ~/.bash_profile
   增加一行
   alias pycharm="/usr/local/bin/charm"
   
4. 修改/usr/local/bin/charm
5. vi /usr/local/bin/charm
6. 增加內容如下: 第44行之後，增加陰影的部分內容。
   7

然後 source ~/.bash_profile
讓剛才的環境變數生效. 這樣不用重新啟動電腦.

測試一下是否有效:


測試成功，確實有效.
發現pycharm 這個有7個字母太長了，我個人建議改短一點。
在vi ~/.bash_profile 檔案裡，增加一個
alias pc="/usr/local/bin/charm"
這樣方便多了，用pc替代pycharm命令, 同時pycharm也可以繼續使用.
修改後完整程式碼如下:

#!/usr/bin/env python
