To fix “permission denied” errors in Claude Code, run chmod +x on the failing command, verify your project directory has 755 permissions, and reset ownership of Claude’s data directory with sudo chown -R $(whoami). If the error persists, check your shell profile for broken sourced scripts and remove any macOS quarantine attributes with xattr -rd com.apple.quarantine. The detailed fixes below cover every common cause.

Understanding the Error
When Claude Code throws a permission denied error, it usually happens in one of three contexts: when executing shell commands through Claude Code, when accessing specific files or directories, or when Claude Code attempts to run its own internal processes. Identifying which context triggers your error determines the right fix.
The error message itself often includes the specific path or command that failed. Pay attention to this detail—it points directly to the source of the problem.
Fix 1: Verify Shell Command Execution Permissions
The most common cause involves Claude Code’s ability to execute shell commands. If your shell cannot run certain commands due to permission issues, Claude Code cannot use them either.
First, check if the command itself has executable permissions:
ls -la /usr/local/bin/your-command
If you see a dash (-) instead of an x in the permissions string, the file is not executable. Fix this with:
chmod +x /path/to/command
For commands installed via Homebrew on macOS, you may need to reinstall them:
brew reinstall package-name
Fix 2: Check Directory and File Access
Claude Code needs read access to your project files and write access to create or modify files. Permission errors occur when the user running Claude Code lacks these permissions.
For Project Files
Verify your project directory permissions:
ls -la /path/to/your/project
If you see permissions like drwx------ or drwxr-x---, only the owner can access the directory. Fix this for your user:
chmod 755 /path/to/your/project
For files within the project:
chmod 644 /path/to/your/project/file
For Sensitive Files
If you are working with files in protected directories (like ~/.ssh or /etc), Claude Code needs explicit permission. Add your user to the appropriate group or adjust permissions carefully:
chmod 700 ~/.ssh
chmod 600 ~/.ssh/id_rsa
Fix 3: Fix Claude Code’s Internal Permissions
Claude Code stores configuration and cache data in specific directories. If these become corrupted or have incorrect permissions, you may see permission denied errors when Claude Code tries to access its own files.
macOS
Check Claude Code’s data directory:
ls -la ~/Library/Application\ Support/Claude/
If permissions look wrong, reset them:
sudo chown -R $(whoami) ~/Library/Application\ Support/Claude/
Linux
Similarly, check the config directory:
ls -la ~/.config/Claude/
Reset permissions with:
sudo chown -R $USER ~/.config/Claude/
Fix 4: Resolve Shell Profile Issues
Sometimes the issue stems from your shell profile (.bashrc, .zshrc, .bash_profile) having commands that fail due to permission errors. When Claude Code spawns a new shell, it may encounter these failures.
Diagnostic Steps
Run your shell profile in verbose mode to identify problematic lines:
bash -x ~/.bashrc
or for Zsh:
zsh -x ~/.zshrc
Look for errors in the output—particularly anything marked “permission denied” or “command not found.”
Common Culprits
-
Commands that write to directories without write permission
-
Sourced scripts that are not executable
-
Environment variables pointing to non-existent or protected paths
Comment out or fix any problematic lines, then restart your terminal session.
Fix 5: Handle macOS Gatekeeper and Quarantine
On macOS, security features can prevent Claude Code or its components from running. If you recently installed Claude Code or updated it, Gatekeeper may have flagged it.
Remove Quarantine Attribute
Check if the Claude Code binary is quarantined:
xattr -l $(which claude)
If you see com.apple.quarantine in the output, remove it:
sudo xattr -rd com.apple.quarantine /Applications/Claude.app
Or for the CLI:
sudo xattr -rd com.apple.quarantine $(which claude)
Allow Claude Code in Security Preferences
If Gatekeeper is blocking Claude Code, open System Preferences → Security & Privacy → General and click “Allow Anyway” next to the blocked software.
Fix 6: Check Sudo and Root Access Issues
If Claude Code attempts to run commands with elevated privileges, your user may lack sudo permissions. Verify your sudo access:
sudo -v
Enter your password when prompted. If this fails, contact your system administrator to add your user to the sudoers file.
For Claude Code itself, avoid running with sudo unless absolutely necessary. Running as root can cause permission issues with files in your home directory.
Fix 7: npm and Node.js Global Package Permissions
A frequently overlooked source of permission errors is npm’s global package directory. If Claude Code uses Node.js tools installed globally via npm, and those tools were installed as root, you will see permission denied errors when Claude Code tries to invoke them as your regular user.
Check where npm stores global packages:
npm config get prefix
If the output is /usr/local or /usr, global npm packages were likely installed as root. The cleanest fix is to redirect npm’s global prefix to a user-owned directory:
mkdir -p ~/.npm-global
npm config set prefix '~/.npm-global'
Then add to your shell profile:
export PATH=~/.npm-global/bin:$PATH
Reload your shell and reinstall any globally needed tools as your regular user (without sudo). Claude Code will then be able to invoke them without permission errors.
Fix 8: Python Virtual Environment and pip Issues
Similar permission conflicts occur with Python tooling. If Claude Code invokes Python scripts or pip-installed CLI tools, and those tools live in a system Python installation, you may see permission denied when Claude Code tries to execute them.
Diagnose which Python is being used:
which python3
which pip3
If these point to /usr/bin/python3 or similar system paths, create a virtual environment for your project and install dependencies there:
python3 -m venv .venv
source .venv/bin/activate
pip install your-dependencies
Claude Code will inherit the activated virtual environment when you launch it from that shell session, eliminating permission conflicts with system-level Python packages.
Diagnostic Tips
When troubleshooting permission errors, gather as much information as possible. Note the full error message text including any file paths or command names, and record what you were asking Claude Code to do when the error occurred. Check whether you recently updated your OS, installed new tools, or modified permissions. Review Claude Code’s log files for more detailed error information.
You can often find logs in:
-
macOS:
~/Library/Logs/Claude/ -
Linux:
~/.config/Claude/logs/
Preventing Future Issues
Once you have resolved the permission error, take steps to prevent recurrence:
-
Use version control to track permission changes in your projects
-
Avoid running Claude Code with elevated privileges unnecessarily
-
Keep your operating system and development tools updated
-
Periodically verify that your project directories have correct permissions
Permission denied errors in Claude Code usually stem from executable permissions on commands, file and directory access, or Claude Code’s own internal data. Start with chmod +x and directory permissions before moving to shell profile debugging or Gatekeeper quarantine removal.
