启动Webserver时，在安装Airflow之后收到此错误。下面是错误，

**from markupsafe import EscapeFormatter
ImportError: cannot import name EscapeFormatter**

Answer 1

解决方法：似乎是与python软件包相关的问题，请尝试检查软件包markupsafe是否位于路径/usr/lib64/python2.7/site-packages/

它确实存在，因此尝试将其导入为from markupsafe import EscapeFormatter in python shell，但同时也给出了相同的错误。可能是文件已损坏。

重新安装软件包并再次导入对我有帮助。

sudo pip uninstall markupsafe
sudo pip install markupsafe

此后，从markupsafe导入EscapeFormatter在python shell中运行良好。

现在启动Airflow Web服务器，它可以正常工作：airflow webserver -p 8080

启动Airflow Webserver时：ImportError：无法导入名称EscapeFormatter
