浅谈Python traceback的优雅处理

刚接触Python的时候，简单的异常处理已经可以帮助我们解决大多数问题，但是随着逐渐地深入，我们会发现有很多情况下简单的异常处理已经无法解决问题了，如下代码，单纯的打印异常所能提供的信息会非常有限。 def func1(): raise Exception("--func1 exception--") def main(): try: func1() except Exception as e: print e if __name__ == '__main__': main() 执行后输出如下： –func1 exception– 通过示例，我们发现

这个错误是由于 Flask-Migrate 的版本问题导致的。你可以尝试升级 Flask-Migrate 的版本，或者降级 Flask-Script 的版本来解决这个问题。具体来说，如果你使用的是 Flask-Migrate 2.5.3 版本，那么你需要将 Flask-Script 降级到 2.0.6 版本。如果你使用的是 Flask-Migrate 3.0 版本，那么你需要升级 Flask-Script 到最新版本。
