Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: ...node_modules/meow/index.js

[armaseg]

When you try to run the CLI command cli.js --azure-connection $AZURE_CONNECTION_STRING --azure-container $AZURE_CONTAINER --aws-bucket $AWS_BUCKET --aws-prefix $AWS_PREF --concurrency 100 you get the following message:

internal/modules/cjs/loader.js:1015
      throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath);
      ^

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /codebuild/output/src293286341/src/node_modules/meow/index.js
require() of ES modules is not supported.
require() of /codebuild/output/src293286341/src/node_modules/meow/index.js from /codebuild/output/src293286341/src/node_modules/azure-blob-to-s3/cli.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /codebuild/output/src293286341/src/node_modules/meow/package.json.

I tested it with node version 15.14.0 and node version 12

Downgrading to "meow": "9.0.0", solves this issue

Oops yes. Will take care of this and then cut a new breaking release with ESM.
