Error: Cannot find module 'x' (MODULE_NOT_FOUND)
Node can’t resolve the module path — the package isn’t installed, or a relative path/extension is wrong.
bash: command not found
The shell can’t find an executable with that name in any directory on your PATH.
Windows Error 0x80070002: The system cannot find the file specified
A file or registry entry Windows expected is missing — common in Windows Update, backups and app installs.
fatal: not a git repository (or any of the parent directories): .git
You ran a Git command outside a Git working tree.
Author identity unknown *** Please tell me who you are.
Git doesn’t know your name and email for commits.
ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.
Build tools (Gradle, Maven, Android tools) can’t find a JDK.
Git: ! [rejected] … (fetch first) — error: failed to push some refs
The remote branch has commits you don’t have locally, so Git refuses to overwrite them. Pull (merge or rebase) first, then push.
You are in 'detached HEAD' state.
HEAD points at a commit instead of a branch, so new commits won’t belong to any branch.
fatal: couldn't find remote ref main
The branch you tried to pull/fetch doesn’t exist on the remote.
java.nio.file.AccessDeniedException: /path
The OS denied a file operation to the Java process.

Node tried to create a file/directory/symlink that already exists.
npm ERR! code ENOTEMPTY — ENOTEMPTY: directory not empty, rename

npm tried to write to a read-only location (read-only container filesystem, mounted volume, or system path).
Warning: include(x.php): Failed to open stream: No such file or directory
PHP couldn’t open a file for include/require/fopen — wrong path, missing file, or no permission.
FileNotFoundError: [Errno 2] No such file or directory: 'data.csv'
Python couldn’t find the file at that path — usually because relative paths resolve from the working directory, not the script.
Error: EPERM: operation not permitted, rename / unlink
The OS refused a file operation — on Windows usually because another process (antivirus, editor, indexer) has the file locked.
No space left on device, but df shows free space (inodes exhausted)
The filesystem has run out of inodes — the slots for files — even though there are gigabytes free, usually because of millions of…
bash: /bin/rm: Argument list too long
A glob like * expanded to more file names than the kernel allows in one command (ARG_MAX), so the command never ran.
mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program
mount couldn’t mount the device — the filesystem type isn’t supported/installed, the partition is wrong, or the filesystem is dam…
Error 0x80070570: The file or directory is corrupted and unreadable
Windows can’t read a file because the disk, USB stick or installation media has corrupted data or bad sectors.
0x80070020: The process cannot access the file because it is being used by another process
Another program has the file open (locked), so Windows can’t modify, delete or replace it.

Yarn isn’t installed (or not enabled through Corepack) on this machine.
