"index.html could not be copied to 404.html." on ng deploy

[yodigi7]

Tried to use the ng deploy however it gave the above error. Also ng build --base-href=/path/ && ngh fails.

Looking at #37 I changed the build output dir to be dist rather than the dist/[PROJECTNAME] default. This caused the ng build --base-href=/path/ && ngh to succeed however ng deploy still fails.

You are mixing the old command line syntax and the new "ng deploy" syntax.

The old command line syntax requires a build by you, it only deploys:

ng build --base-href=/path/
npx angular-cli-ghpages [OTHER OPTIONS]

The new "ng deploy" syntax builds and deploys. Therefore only in the new syntax the --base-href option is available:

ng deploy --base-href=/path/ [OTHER OPTIONS]
