I tried changing my username and home directory on my Windows 10 machine recently, and I got 95% of the cases out of the way, but npm is one of the last ones. The error you're seeing means that npm thinks that my home directory is at c:\Users\Joshua Holbrook instead of c:\Users\Josh. 🙃 So the question is, how do I trace this back to the code that decides where my home directory is?

err.log

PS C:\Users\Josh> npm
