devcontainer: fix pnpm install EACCES on first container creation#2346
Merged
Conversation
Docker named volumes mounted at ts/node_modules, the pnpm global store, and the Claude config directory are created as root:root, which prevented the non-root codespace user from running pnpm install on first container creation. post-create.sh now sudo chowns these mount points to codespace before invoking pnpm install. README gains a troubleshooting entry with manual recovery steps. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Problem
On first creation of the devcontainer,
pnpm installfails withEACCES: permission deniedwriting intots/node_modules.Root cause
.devcontainer/devcontainer.jsonmounts three Docker named volumes:${containerWorkspaceFolder}/ts/node_modules/home/codespace/.local/share/pnpm/store/home/codespace/.claudeDocker creates the mount-point directories owned by
root:root. The container'sremoteUseriscodespace(UID 1000), so whenpost-create.shrunspnpm installascodespaceit can't write intots/node_modules(or populate the global pnpm store).Fix
.devcontainer/scripts/post-create.sh: before runningpnpm install,sudo chown -R codespace:codespacethe three mounted volume paths. Thetsworkspace path is discovered dynamically so worktrees keep working..devcontainer/README.md: document the symptom and a manual recovery command in the Troubleshooting section.Reviewer notes
