Repro steps

• npx @angular/cli@next new ng6app
• cd ng6app
• ng build

Observed behavior

When I run ng build in Command Prompt, it failed.

Path "g:/Projects/ng6app" must be absolute.

**When I open this folder and open Terminal to run the same command, it works! **

Desired behavior

It suppose can run these command both in Command Prompt and in Terminal of VSCode.

Mention any other details that might be useful (optional)

I tried to output the problem path. In Command Prompt, the path start with 'G:/'. In Terminal window of the VSCode, it do start with '/'. (Why?)
