Can no longer use lerna publish, fails with error

[phun-ky]

We can no longer publish packages when using lerna publish, it fails with error:

ERR! lerna bump must be an explicit version string _or_ one of: 'major', 'minor', 'patch', 'premajor', 'preminor', 'prepatch', 'prerelease', 'from-git', or 'from-package'.

It seems I'm suddenly hitting this:

lerna/commands/version/command.js

Line 254 in ac8385d

if (!semver.valid(choice) && semverKeywords.indexOf(choice) === -1) {

For no apparent reason..

Expected Behavior

Using this unchanged command:

$ lerna publish --exact --loglevel=warn --registry=https://<projec>.myget.org/F/<category>/auth/<token>/npm/ --yes --no-verify-access --no-verify-registry -- --unsafe-perm --loglevel=warn

I expect that packages are published

Current Behavior

I'm getting the formentioned error.

Possible Solution

This worked 7+ days ago, did something break? A breaking change?

Steps to Reproduce (for bugs)

Run above command

lerna.json

This is definitely a bug, thanks for the report. I believe I have a workaround.

Also, note that arguments after -- are no longer passed to subprocess executions of npm, since v3.7.0.

[evocateur]

v3.18.3

@evocateur thanks! btw, where can I find documentation on the subprocess executions? (passing args after -- ?

[evocateur]

https://github.com/lerna/lerna/tree/master/commands/exec#usage and https://github.com/lerna/lerna/tree/master/commands/run#usage are the places that document when/if a -- is necessary. Those are the only commands that need it.

I ran into this error due to an empty string at the end of the publish command:

lerna publish --yes --npm-tag latest --repo-version 1.0.0 '' - notice the '' at the end.

The above publish command was generated inside a bash function that sometimes took a parameter:

lerna_publish_to () {
  lerna publish --yes --npm-tag latest --repo-version 1.0.0 "$1"
}

When the parameter was not included in the function call, we get the above command and lerna throws the error.

lerna_publish_to --skip-git # works
lerna_publish_to # fails

The fix is some arcane bash:

lerna_publish_to () {
  lerna publish --yes --npm-tag latest --repo-version 1.0.0 ${1:+"$1"}
}
