There have been a number of commits in the history for `rimraf` which
indicate others have also been struggling with ENOTEMPTY, specifically
on Windows.
https://github.com/isaacs/rimraf/commits/master
This commit, included in 2.6.1 takes a relatively aggressive approach:
d53235de86
However, due to the way the Windows filesystem is designed, this
approach may be the only way of coping with file-handles which are
cached by the OS and not released immediately upon closing a file
(in other words, at a time that Meteor would think it'd be safe to
remove the file/directory).
Attempts to help with meteor/meteor#8485.
This fixes a bug affecting namespace imports/exports such as
export * from "module"
import * as ns from "module"
where "module" is a CommonJS module that sets module.exports to an
object-like value that is not actually an object, e.g. a function.
The reify commit that fixed this bug includes a test demonstrating an
example of one such library (lodash):
benjamn/reify@b69a600e65
This is a change that was necessary on the wip-upgrade-to-node-6 branch,
and it seems better to ship it sooner rather than waiting:
meteor/meteor@d823812e85
The `winston` npm package is not an ECMAScript module, but it does export
a "default" property, and this property was accidentally clobbering the
"default" property of the namespace object, thus interfering with default
import syntax:
import winston from "winston"
Specifically, the `winston` variable would end up referring to
`require("winston").default`, rather than `require("winston")`.
Nothing is lost by fixing this problem, as you can still refer to
`winston.default` if you need to access that property.
