我正在本地测试它，我有一个 ~/.aws/config 文件。

~/.aws/config 看起来像：

[profile a] 
...
[profile b]
...

我还有一个 AWS_PROFILE 环境变量设置为“a”。

我想读取一个文件，使用 pandas 可以通过配置文件 b 访问该文件。

我可以通过以下方式访问它s3fs：

import s3fs
fs = s3fs.S3FileSystem(profile="b")
fs.get("BUCKET/FILE.parquet", "FILE.parquet")
pd.read_parquet("FILE.parquet")

但是，如果我尝试使用 storage_options 将其传递给 pd.read_parquet，我会得到一个PermissionError: Forbidden.

pd.read_parquet(
    "s3://BUCKET/FILE.parquet",
    storage_options={"profile": "b"},
)

The above exception was the direct cause of the following exception:
