如何告诉Babel CLI忽略其中带有“ __”的任何路径？

Question

"@babel/cli": "^7.2.3",

Seems really simple.

https://babeljs.io/docs/en/babel-cli#ignore-files

 babel src --out-dir lib --ignore "src/**/*.spec.js","src/**/*.test.js"

So I set it up like so:

babel src --out-dir cjs --ignore "**/_*" --copy-file --watch

Glob reference: https://github.com/isaacs/node-glob

But I see this in the output:

add:cjs/__mocks__/@xyz/common-fn.js
add:cjs/middleware/__mocks__/uuid.js 

OK I try this:

babel src --out-dir cjs --ignore "**/_+","_+" --copy-file --watch

And these:

babel src --out-dir cjs --ignore "**/_*/*.*\ --copy-file --watch 
babel src --out-dir cjs --ignore "**/__mocks__/*.*",  --copy-file --watch 
babel src --out-dir cjs --ignore "[src|middleware]/**/__mocks__/*.*" --copy-file --watch"
babel src --out-dir cjs --ignore "**/_+/**/*.*" --copy-file --watch

Same result every time. It really seems like that last one should work: ignore any path with zero or more directories followed by a directory that has at least one _ in the name, then zero or more directories then a file matching any pattern. Am I reading that right?

Then I tried being very specific:

babel src --out-dir cjs --ignore "nes/middleware/__mocks__/*.js", --copy-file --watch

And I get:

add:nes/middleware/__mocks__/localize.js

I can't tell if this is a bug in Babel or me misunderstanding glob patterns.

There seems to be some debate about whether Babel fully supports Glob patterns at the CLI level.

I managed to get it working with this ignore pattern:

--ignore "src/**/__mocks__/**/*.js" --ignore "src/**/*.test.js"

This pattern **/__*/** will work in Glob but fails in Babel.
