1

go get -u github.com/unixpickle/gobfuscate

Worked.

2

gobfuscate ./src ./bin

'gobfuscate' is not recognized as an internal or external command,
operable program or batch file.

Tried using the compiled binary via go install:

C:\Users\0\Desktop$\dev\Go\Gobfuscate> .\gobfuscate ./src ./bin
2023/03/27 21:48:07 Copying GOPATH...
Failed to copy into a new GOPATH: import "./src": import relative to unknown directory
Note: Setting GO111MODULE env variable to off may resolve the above error.

Set the GO111MODULE to off via set GO111MODULE=off

C:\Users\0\Desktop$\dev\Go\Gobfuscate> .\gobfuscate ./src ./bin

How?
