# VSCode Extension Installation Regression: "1: 1" Error
|

**Reported**: 2025-12-16

**Status**: Under Investigation

## Description
|
||
|
|
|
||
|
|
Users are unable to use the VSCode IDE integration when running Claude Code in a Homespace (containerized environment). The `/ide` command initially reports success, but a few seconds later an error appears.
|
||
|
|
|
||
|
|
### Error Message
|
||
|
|
|
||
|
|
```
|
||
|
|
IDE: ✘ Error installing VS Code extension: 1: 1
|
||
|
|
Please restart your IDE and try again.
|
||
|
|
```
|
||
|
|
|
||
|
|
## Steps to Reproduce
|
||
|
|
|
||
|
|
1. Run Claude Code in a Homespace environment
|
||
|
|
2. Execute `/ide` command
|
||
|
|
3. Observe initial success message
|
||
|
|
4. Wait a few seconds - error popup appears
|
||
|
|
5. Run `/status` to confirm the error
|
||
|
|
|
||
|
|
## Root Cause Analysis
|
||
|
|
|
||
|
|
### Error Pattern Analysis
|
||
|
|
|
||
|
|
The error message `1: 1` follows the pattern from the extension installation error handling:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
throw Error(`${result.code}: ${result.error} ${result.stderr}`)
|
||
|
|
```
|
||
|
|
|
||
|
|
For "1: 1" to appear, the values must be:
|
||
|
|
- `result.code` = 1 (exit code from VS Code CLI)
|
||
|
|
- `result.error` = "1" (incorrectly set to the exit code instead of error message)
|
||
|
|
- `result.stderr` = "" (empty)
|
||
|
|
|
||
|
|
### Regression Hypothesis
|
||
|
|
|
||
|
|
The async execution result object is incorrectly populating the `error` field with the numeric exit code instead of the actual error message from stderr. This appears to be a regression in subprocess output parsing.
|
||
|
|
|
||
|
|
### Timeline
|
||
|
|
|
||
|
|
- **Working**: Last week (user confirmed)
|
||
|
|
- **Broken**: Current version (2.0.59+)
|
||
|
|
- **Likely introduced**: Between versions 2.0.59-2.0.70
|
||
|
|
|
||
|
|
## Environment
|
||
|
|
|
||
|
|
- Running in Homespace (containerized environment)
|
||
|
|
- VSCode Remote development setup
|
||
|
|
|
||
|
|
## Temporary Workaround
|
||
|
|
|
||
|
|
If experiencing this issue, try:
|
||
|
|
|
||
|
|
1. Manually install the Claude Code extension in VS Code:
|
||
|
|
- Open VS Code Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
|
||
|
|
- Type "Extensions: Install Extension"
|
||
|
|
- Search for "Claude Code" (by Anthropic)
|
||
|
|
- Install manually
|
||
|
|
|
||
|
|
2. After manual installation, restart your IDE and try `/ide` again
|
||
|
|
|
||
|
|
## Related Changes in CHANGELOG
|
||
|
|
|
||
|
|
Potentially relevant recent changes:
|
||
|
|
- 2.0.64: VSCode: Fixed extension not working on Windows ARM64
|
||
|
|
- 2.0.62: Fixed IDE diff tab not closing when rejecting file changes
|
||
|
|
- 2.0.61: Reverted VSCode support for multiple terminal clients
|
||
|
|
- 2.0.60: VSCode: Added support for multiple terminal clients
|
||
|
|
- 2.0.59: VS Code: Fixed .claude.json config file being read from incorrect location
|
||
|
|
|
||
|
|
## Fix Required
|
||
|
|
|
||
|
|
The fix needs to address how subprocess execution results are parsed, specifically ensuring that:
|
||
|
|
1. The `error` field contains the actual error message (from stderr), not the exit code
|
||
|
|
2. Proper error handling for when VS Code CLI fails in containerized environments
