没有凭证错误

Question

我试图设置动态缩略图服务thumbor并支持s3作为存储，我需要为AWS设置此社区支持的pip库 。

它在我的本地环境上运行良好，但是当我尝试将其托管在我们的一台服务器上时，出现了NoCredentialsError。 我假设这是因为botocore的版本不同（最新版本和pip库安装的最新版本）。 这是错误日志：

可以通过正确的安装顺序来解决此问题吗？ 因为pip库会删除现有的较新版本的botocore并安装较旧的版本。

我正在使用主管运行进程，似乎进程无法访问AWS凭证

通过正确配置主管可以解决此问题。 主管启动的进程用户无权访问配置文件

通过正确配置主管可以解决此问题。 由主管启动的子流程用户无权访问aws配置文件。 因此，它是与本地环境一起工作或单独创建过程，而不与主管一起工作。
