64位ubuntu16.04下pycharm无法切换fcitx输入法和无法输入中文的问题
首先root权限下面输入：
dpkg -l |grep fcitx
得到，看看有什么没有安装的：

然后注意pycharm.sh中环境变量的添加位置，注意千万不要把fcitx
相关的三行添加到最后，那样就无效了。正确的添加方法如下（下面
是确保fcitx可以在pycharm中切换出来并且可以输入中文的整个
pycharm.sh的内容）：
gedit /home/appleyuchi/Downloads/pycharm-2017.1.2/bin/pycharm.sh
内容为（注意红色字体添加的具体位置，添加位置出错则直接导致无效）：

改完pycharm.sh文件后，保存后，注销下linux，就可以生效了。
