Deprecated use of non-string passed to loaderUtils.parseQuery()

[mdittmer]

(node:35555) DeprecationWarning: loaderUtils.parseQuery() received a non-string value which can be problematic, see https://github.com/webpack/loader-utils/issues/56
parseQuery() will be replaced with getOptions() in the next major version of loader-utils.

> npm list istanbul-instrumenter-loader 
...
└── istanbul-instrumenter-loader@2.0.0 

> npm --version
3.10.9

> node --version
v7.2.0

This issue appeared to go away after

> npm uninstall istanbul-instrumenter-loader
> npm install --save-dev istanbul-instrumenter-loader@3.0.0

However, I had previously done:

> npm uninstall istanbul-instrumenter-loader
> npm install --save-dev istanbul-instrumenter-loader

Any idea why the latest release was not the default install version?

@mdittmer maybe npm cache clean? also twice check your package.json

v3.0.0 should be @latest on npm, your cache may be corrupt. In case there are still any regressions feel free to reopen
