Cannot install webpack-cli without bash

[SIkebe]

Describe the bug
npm install webpack-cli fails if you don't have bash in your PATH.
v3.2.1 worked but v3.2.2 fails.

To Reproduce

mkdir webpack-demo && cd webpack-demo
npm init -y
npm install webpack webpack-cli --save-dev
> webpack-cli@3.2.2 postinstall C:\webpack-demo\node_modules\webpack-cli
> webpack-cli-donate

'bash' is not recognized as an internal or external command,
operable program or batch file.
npm WARN webpack-demo@1.0.0 No description
npm WARN webpack-demo@1.0.0 No repository field.

npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.7: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! webpack-cli@3.2.2 postinstall: `webpack-cli-donate`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the webpack-cli@3.2.2 postinstall script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Expected behavior
npm install works regardless of bash existence or clear documentation of requirement for bash.
