ERROR: at least one staged file: "${fPath}"
|
|
has a more recent modification timestamp than the documentation file:
|
|
"${docFile}"
|
|
|
|
This probably means that \`npm run build\` or \`npm test\` have not been executed,
|
|
and this error can be fixed by doing so. Running \`npm run build\` or \`npm test\`
|
|
before commiting is required in order to update the CLI markdown documentation
|
|
(in case any command-line options were updated, added or removed) and also to
|
|
catch Typescript type check errors sooner and reduce overall waiting time, given
|
|
that the CI build/tests are currently rather lengthy.
|
|
|
|
If you need/wish to bypass this check without running \`npm run build\`, run:
|
|
npx touch -am "${docFile}"
|
|
and then try again.
