Before the changes:

error: environment variable `HOME` not defined
  --> src\pkg\core\http.rs:61:25
   |
61 |         format!("{}{}", env!("HOME"), cookie_path.trim_start_matches('~'))
   |                         ^^^^^^^^^^^^
   |
   = note: this error originates in the macro `env` (in Nightly builds, run with -Z macro-backtrace for more info)

error: could not compile `binggpt` due to previous error
warning: build failed, waiting for other jobs to finish...

After the changes:

C:\Users\shawn\GitHub\BingGPT>cargo build
