我正在使用python 2.7和boto3最新版本的Windows 10计算机上。另外，我正在使用cz_freeze 5.2.0版本从python代码创建一个.exe。
项目简要视图：
我正在创建一个可部署的工具，该工具使用boto3以编程方式下载和上传S3存储桶中的对象。可执行文件在我的机器上运行得很好，因为〜/ .aws文件夹中已经存在凭据。但是，当我在另一台计算机上复制可执行文件时，它总是抛出一个错误，说它无法找到凭据。
我尝试通过3种方式解决问题。
在冻结它之前，我在setup.py文件中包含了.aws文件夹。但是，它会从可执行文件所在的文件夹中读取凭据。
我还尝试将.aws文件夹的路径添加为环境变量，但它也无法找到凭据
我将S3存储桶中的文件夹更改为授予完全公共访问权限，并尝试运行该程序，但是它仍然在寻找凭据。
请帮助我。我的解决方案用完了。我已经粘贴了完整的追溯错误：
