pycharm远程调试, 连接上代码无法补全问题

Couldn't refresh skeletons for remote interpreter
			failed to run generator3/__main__.py for sftp://[email protected]:22/usr/local/bin/python3, exit code 1, stderr:

解决办法

1. 在远程主机上删掉用户目录中的**~/.pycharm_helpers**目录(在pycharm上设置的远程账号用户和执行bash命令的用户要一致)

rm -rf ~/.pycharm_helpers

2. 在pycharm上把原来的Interpreter全部删掉, 重新配置一遍Interpreter解释器apply应用确定即可
   
3. 看到远程库文件加载成功了, 就说明可以了!
