Are you running cmd as Administrator? If not, you probably should be. Right-click cmd > Run as administrator:

Can you try uninstalling ionic and reinstalling it?

npm uninstall -g ionic
npm install -g ionic

I was getting this same message trying to install ionic-cli myself this morning (Windows 10 x64).. I didn't think to check what version I already had, but the command npm i -g ionic spat out the same error as seen in this issue.

I must say, I did already have 3.19.0 installed, not sure if that has anything to do with this... To be safe, I tried removing and reinstalling it, which ran through without any issues:

D:\>npm un -g ionic
removed 250 packages in 5.323s

D:\>npm i -g ionic
C:\nodejs\ionic -> C:\nodejs\node_modules\ionic\bin\ionic
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.3 (node_modules\ionic\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.3: wanted {"os":"darwin","arch":"any"} (curr
ent: {"os":"win32","arch":"x64"})

+ ionic@3.19.0
added 366 packages in 57.359s

Another interesting point to keep in mind here: I run my NodeJS environments using nvm-windows. This means my C:\nodejs folder is actually symbolic link, as per the following line from dir:

2017-11-09  09:23    <SYMLINKD>     nodejs [C:\Users\agreeff\AppData\Roaming\nvm\v6.12.0]

@ZaLiTHkA Thanks for providing some insight into this issue. I hope others who find this can fix it in the same way.

This looks to be a glitch/hiccup issue with npm on Windows. If frequency increases, I will look into it with npm.

It took me quite a long time to find out that it may happen you are trying to install/uninstall any package that depends on Ionic, and Ionic is running.
