AWS S3 - 无法识别配置文件信息答案

【问题标题】：AWS S3 - failed to identify the profile informationAWS S3 - 无法识别配置文件信息
【发布时间】：2017-06-21 20:41:30
【问题描述】：

我正在使用 boto3 与 AWS S3 进行通信。我首先尝试使用我的本地系统。它成功连接并且工作正常。我将代码移至服务器（flask-apache2）。现在代码不起作用。即使我将参数设置在~/.aws/credentials 和~/.aws/config 上，它也会显示ProfileNotFound: The config profile (dev) could not be found 异常

~/.aws/credentials 文件：

[dev]
aws_access_key_id = *****************
aws_secret_access_key = *********************

~/.aws/config 文件：

[default]
region = us-west-2
output = json

[profile dev]
region = us-west-2
output = json

这是我访问个人资料的方式：

session = boto3.Session(profile_name='dev')
s3 = session.resource('s3')

错误日志：

session = boto3.Session(profile_name='dev')

【问题讨论】：

凭证文件很可能与运行它的用户环境不同。
你能提出一些解决办法吗？

【解决方案1】：

终于找到了解决办法！

我将 AWS 凭证和配置文件路径添加到 apache2 envvars 文件。问题就解决了。

步骤：

$sudo nano /etc/apache2/envvars
     # Added the following lines
     export AWS_CONFIG_FILE=/home/ubuntu/.aws/config
     export AWS_SHARED_CREDENTIALS_FILE=/home/ubuntu/.aws/credentials

sudo service apache2 reload | sudo service apache2 restart

完成！它开始工作正常！

我最初尝试添加 AWS_CONFIG_FILE=~/.aws/credentials。 这不起作用。必须给出完整的路径。
