Yep! Got the same issue, not sure why

I also encountered the same issue. I'm using IDEA 2024.3.7, Claude plugin 0.1.14-beta, and Claude Code CLI 2.1.5

Windows same, and I add tmpclaude-* to .gitignore。

same here on windows. it's making claude code unusable for tonight, many manual clean-ups

same here on windows.

Same issue

As I assume the claude team will look at this issue, PLEASE also fix this related tmpdir issue: https://github.com/anthropics/claude-code/issues/15700

I suspect you can fix this by having this env variable set to your tmp although i didn't try it yet
export CLAUDE_CODE_TMPDIR=

Actually, this is a path conversion issue, not a problem with the path itself.

And I’ve already provided the fix earlier.

Why does it seem like none of you can see it?

It's really sad, I can't even temporarily switch to OpenCode now.

rollback to the older version helps

$ claude install stable

rollback to the older version helps `` $ claude install stable ``

 $ claude install stable --force

It's work

If you’re using the bun version of Claude Code, this won’t work for you. please use the npm package version instead.

If you’re using the npm package version of Claude Code,
you can also adjust the scan path specified at the beginning of the script yourself.

same issue here.

Just ran the update from 2.1.2 to 2.1.5 and experienced this issue immediately after updating.

Additional Technical Details

Observed behavior:

• Every Bash tool invocation creates a tmpclaude-XXXX-cwd file in the working directory
• File contains just the current working directory path

Root cause identified:
Claude Code appends this to every bash command:

pwd -P >| \tmp\claude-XXXX-cwd

The backslash path \tmp\claude is being mangled - the \t appears to be interpreted/stripped, resulting in tmpclaude written to the CWD instead of /tmp/claude-XXXX-cwd.

Reproduction:

• Windows 11 with Git Bash
• Claude Code 2.1.5 (appears to be a regression in this version)
• Working directory on H: drive (network/mapped drive), though may affect C: drive as well

Workaround:
Added tmpclaude* to .gitignore to prevent them from being tracked.

Process evidence:

wmic process get commandline | grep claude

Shows the bash wrapper command with the problematic \tmp\claude-XXXX-cwd path.

Sorry about that folks, I have a fix up for this.

still broken

this should be a hotfix

still broken

FYI, still not fixed in v2.1.6

sorry @amorriscode , I didn't understand why this issue was closed. I have this version and it's also broken for me, which is a bit annoying 😟. Could you share if your patch is planned for the next weeks?
It's sad to see "shipping fast" be more important than quality software, I really like claude code...

why do these issues keep getting closed when there is no resolution?

Because 2.1.7 has already been fixed.

1 hour ago

我在wsl環境沒問題，結果今天把環境換到powershell也一樣遇到了

2.1.7 still creates tmp files in the project (I'm using Powershell).

Sometimes, it even creates a file named nul.

EDIT: after a major testing, I din't had any new tmp file. Fixed for me

2.1.7 still creates tmp files in the project (I'm using Powershell). Sometimes, it even creates a file named nul.

nul file is because it outputs to null and you're on windows not linux... e.g. /dev/null 2>&1 has nothing to do with this problem.

Then, there is an issue somewhere in Claude’s code that tries to use Linux syntax on Windows, right?

@amorriscode sorry folks, the issue got auto-merged when the PR was merged but the fix doesn't go out until the following Claude Code release. This was fixed in 2.1.7.

@amorriscode - the issue looks like closed by you, as a person, in https://github.com/anthropics/claude-code/issues/17568#issuecomment-3740527447 https://github.com/anthropics/claude-code/issues/17568#event-22000218933

It does not look like auto-closed by a bot, unless I'm wrong by looking at the appearance.
Could you provide more details so the release process will be better understood in the future?

Also this still is broken in 2.1.7 for me, windows machine

@amorriscode各位，不好意思啊，这个问题在 PR 合并时自动关闭了，但修复要到下一个 Claude Code 版本发布才会生效。这个 bug 已经在 2.1.7 版本里修好啦。

My version is 2.1.7, but it still creates files in the project directory

I'm having the same issue on Windows 11 with Claude Code 2.1.7

same....
