s3_source doesn't work

Neither provider: "env" nor id: <aws_access_key_id>, secret: <aws_secret_access_key> work when used in the .gemrc file.

Both methods result in an error:

ERROR:  Could not find a valid gem 'mygem' (>= 0), here is why:
          Unable to download data from s3://bucket1 - credentials needed in s3 source, like s3://key:secret@bucket-name/ (s3://bucket1/latest_specs.4.8.gz)

I've verified that the S3 contents match what gem expects:

$ aws s3 ls s3://bucket1
                           PRE gems/
                           PRE quick/

Any help is much appreciated, thanks!

    Hi Brian,

    Can you please show us your ,gemrc? make sure you have masked id, secret, and any other sensitive info before sharing.
    Also, please confirm that sources value ends with a trailing slash and you have specified the region of the bucket.

    I've tried both of these, and `echo $AWS_<variables>` to make sure the env
    was correct in the first case:

    - s3://myBucket/
    s3_source: {
      myBucket: {
        provider: "env",
        region: "us-west-2"

    - s3://myBucket/
    s3_source: {
        id: "omitted",
        secret: "omitted_also",
        secret_token: "omitted_also_also", region: "us-west-2"

    Your config seems correct to me. What the version of your rubygems gem -v? Can you please try gem install mygem --verbose and send us the output? Does gem install mygem -v 3.0.1 --source s3://<AWS_ACCESS_KEY_ID>:<AWS_SECRET_ACCESS_KEY>@bucket1 also not work for you?
