【问题描述】：

我正在尝试设置动态缩略图服务thumbor 并支持 s3 作为存储，我需要设置这个社区支持的pip library for aws。

它在我的本地环境中运行良好，但是当我尝试在我们的一台服务器上托管它时，我收到 NoCredentialsError。我假设这是因为 botocore 的不同版本（最新的一个和一个由 pip 库安装）。这是错误日志：

可以通过我安装库的正确顺序来修复它吗？因为 pip 库删除了现有的较新版本的 botocore 并安装了旧版本。

编辑：

我正在使用主管运行进程，但似乎进程无法访问 aws 凭据

编辑 2：

通过正确配置主管解决了该问题。主管启动的进程的用户无权访问配置文件

【问题讨论】：

您的服务器似乎没有正确配置凭据。你如何在你的服务器和你的开发机器上设置你的凭据？关于版本，tc_aws 似乎对 botocore 1.2.0 有很强的依赖关系，因此如果升级超过该版本，它可能无法正常工作。
是的，tc_aws 将 botocore 降级到 1.2.0。使用当前配置，我尝试使用 boto3 从命令行连接到 s3 存储桶，它可以工作。我不知道安装这些库的正确顺序是什么。
@JordonPhillips 我想我解决了这个问题。我正在使用主管运行进程，然后进程无法访问 aws 凭据
似乎是您的问题的一部分原因是不使用 virtualenv。您不应该使用“sudo pip”安装软件包。
@mootmoot 是的，应该使用 virtualenv 并且不使用 sudo 进行 pip 安装

【解决方案1】：

通过正确配置主管解决了该问题。主管启动的子进程的用户无权访问 aws 配置文件。因此，它与本地环境一起工作或单独创建流程，但与主管无关。
