有没有办法通过flask应用程序安装python软件包?
我有一个flask应用程序,它使用exec(script_name,globals())执行脚本,并使用docker在Google Cloud中运行。我所有的脚本都在谷歌云存储中。所以我使用gcsfs模块从GCS读取脚本并执行 例如:有没有办法通过flask应用程序安装python软件包?,python,google-cloud-platform,google-cloud-run,Python,Google Cloud Platform,Google Cloud Run,我有一个flask应用程序,它使用exec(script_name,globals())执行脚本,并使用docker在Google Cloud中运行。我所有的脚本都在谷歌云存储中。所以我使用gcsfs模块从GCS读取脚本并执行 例如: exec(gcs_file_system.open(<script_from_cloud>).read(), globals()) 所有这些都尝试在script.py中执行,我使用 exec(gcs_file_system.open('bucket_

每次我尝试上述任何一种方法时,要么会出现上游断开连接错误,要么脚本就失败了。我真的需要一些帮助或建议,告诉我如何通过在云中运行的flask应用程序(Google cloud Run)安装软件包。安装软件包可以通过定义另一个路由函数来完成,只需安装软件包 这是通过在单独的路由函数中提供以下语句而不是指定在路由函数中的另一个exec(script)函数中安装包来实现的

在您的工作站上工作吗?你试过你的容器吗?它在我本地的机器上工作。。但是不能在容器中工作它不能在本地机器上的容器中工作,对吗?这并不奇怪,因为您在内存中加载了容器,使用python运行时,您可以动态更新python运行时。有些东西闻起来像是一个错误的想法/设计。我通过在单独的路由函数中提供exec(os.system('pip install package')、globals()来修复它,而不是在另一个exec()脚本中提供它。很有意思。将其作为答案发布!
