1.打开Pycharm

3. 打开命令行窗口，编辑环境文件~/.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. 增加内容如下: 第44行之后，增加阴影的部分内容。 7

然后 source ~/.bash_profile 让刚才的环境变量生效. 这样不用重新启动电脑.

测试一下是否有效: 测试成功，确实有效. 发现pycharm 这个有7个字母太长了，我个人建议改短一点。 在vi ~/.bash_profile 文件里，增加一个 alias pc="/usr/local/bin/charm" 这样方便多了，用pc替代pycharm命令, 同时pycharm也可以继续使用. 修改后完整代码如下:

#!/usr/bin/env python
