lerna failed to use the correct git binary

Some background, I’m using CentOS + Git 2.18 SCL, since lerna requires git --first-parent switch the vendor-provided git 1.8 does not have (#1726).

The bug is, even after git 2.18 has been enabled for the current shell, lerna keeps using the old 1.8.3 version. It seems to be a bug of execa@^1.0.0.

Expected Behavior

Git 2.18 is used, and no error is thrown.

Current Behavior

Git 1.8.3 is used, and the following error is thrown:

lerna ERR! Error: Command failed: git describe --always --long --dirty --first-parent --match v*.*.*
lerna ERR! error: unknown option `first-parent'

Possible Solution

Upgrade execa.

In the same directory lerna is setup (thus using execa@^1.0.0), the following script

const childProcess = require('child_process')
const execa = require('execa')
childProcess.exec('which git', (error, stdout, stderr) => console.log(stdout))
childProcess.exec('git --version', (error, stdout, stderr) => console.log(stdout))
execa('which', ['git']).then(({stdout}) => console.log(stdout))
execa('git', ['--version']).then(({stdout}) => console.log(stdout))

outputs

/opt/rh/rh-git218/root/usr/bin/git
git version 2.18.1
/usr/bin/git
git version 1.8.3.1

However, in a folder with the latest execa@^4.0.0 installed, the above script outputs:

/opt/rh/rh-git218/root/usr/bin/git
git version 2.18.1
/opt/rh/rh-git218/root/usr/bin/git
git version 2.18.1

Steps to Reproduce (for bugs)

1. Set up and enable rh-git218 for current shell
2. Run lerna publish --canary --preid rc --pre-dist-tag next

lerna.json

{
  "version": "0.1.0",
  "npmClient": "yarn",
  "command": {
    "publish": {
      "message": "chore(release): publish",
      "registry": "https://gitlab.com/api/v4/projects/12345678/packages/npm/"
    }
  },
  "useWorkspaces": true,
  "packages": [
    "packages/*"
  ]
}

What git version are you using ? Using git 2 or above solves this issue

The issue is not about git version, but when two different versions of git executable exist on the system, lerna failed to use the correct one (git 2 or above).

Like I said, upgrading the dependency to execa@^4.0.0 will solve this issue, which also proves it’s not a setup issue.

Btw, I’m not sure if things have changed since I opened this, I’m not using lerna anymore (mostly because of this issue).

v4.0.0 is now available as lerna@next, which should resolve this issue. Please update if that’s not the case.

I have upgraded to V4.0.0, but I still get lerna ERR in gitlab CI! （Error: unknown option ）How can I use commands to solve this problem？ If the includeMergedTags are true, it will filter out --first-parent, but gitLab CI will still report the error @evocateur
