What's Wrong?

From version 2.0.55 till 2.0.74, when you have a custom ANTHROPIC_BASE_URL, the initialisation of ~/.claude.json fails. It tries to connect to api.anthropic.com, which is blocked for our organisation. Moreover, I am able to get around this by installing 2.0.54 first, and then installing the latest (2.0.74) at this time.

I'm trying to provision claude code for 500+ people, so custom workarounds is something I'd like to prevent. After going past the "init" phase of getting ~/.claude.json created, I am able to upgrade, so my theory is that there is a bug in that part of the code. After upgrading ANTHROPIC_BASE_URL is respected again.

What Should Happen?

ANTHROPIC_BASE_URL should be respected on first run

Error Messages/Logs

Steps to Reproduce

Install latest version of claude code, with settings preconfigured in ~/.claude/settings.json to point to a different endpoint, that endpoint will not be respected. ~/.claude.json should not be present. It will not be created.

The duplicates are not the same, albeit related.

Encountered the same issue in 2.0.76.

I've encountered the same problem: the ANTHROPIC_BASE_URL env is not working.

My workaround for this is to add "hasCompletedOnboarding": true to ~/.claude.json within a script that I have people run instead of running claude directly.

# Check and ensure hasCompletedOnboarding is set in ~/.claude.json
CLAUDE_JSON="$HOME/.claude.json"
if [ -f "$CLAUDE_JSON" ]; then
  # File exists, check if hasCompletedOnboarding is true
  HAS_ONBOARDED=$(jq -r '.hasCompletedOnboarding // false' "$CLAUDE_JSON" 2>/dev/null)
  if [ "$HAS_ONBOARDED" != "true" ]; then
    # Set hasCompletedOnboarding to true
    UPDATED_JSON=$(jq '.hasCompletedOnboarding = true' "$CLAUDE_JSON" 2>/dev/null)
    if [ $? -eq 0 ] && [ -n "$UPDATED_JSON" ]; then
      echo "$UPDATED_JSON" > "$CLAUDE_JSON"
      chmod 600 "$CLAUDE_JSON"
    fi
  fi
else
  # File doesn't exist, create it with hasCompletedOnboarding set to true
  echo '{"hasCompletedOnboarding": true}' > "$CLAUDE_JSON"
  chmod 600 "$CLAUDE_JSON"
fi
