Can't install package / EEXIST #44

Running npm install --save-dev wrap-ansi results in the following error:

npm ERR! code EEXIST
npm ERR! syscall mkdir
npm ERR! path ...\test\node_modules\wrap-ansi\node_modules
npm ERR! errno -4075
npm ERR! EEXIST: file already exists, mkdir '...\test\node_modules\wrap-ansi\node_modules'
npm ERR! File exists: ...\test\node_modules\wrap-ansi\node_modules
npm ERR! Remove the existing file and try again, or run npm
npm ERR! with --force to overwrite files recklessly.

npm: 6.14.6 node: v12.18.4 os: Windows 10 (10.0.18363)

Note that I have node and npm installed in the user context (C:\users\user\AppData\Local\Programs\nodejs[node.exe | npm.cmd]).

Please advise. This is preventing me from installing mocha.
