Java couldn’t open the file — wrong path relative to the working directory, missing file, or a classpath resource read as a file.
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.
Error: EEXIST: file already exists, mkdir
Node tried to create a file/directory/symlink that already exists.
No space left on device, but df shows free space (inodes exhausted)

bash: command not found
The shell can’t find an executable with that name in any directory on your PATH.

A file or registry entry Windows expected is missing — common in Windows Update, backups and app installs.
npm ERR! code EACCES — permission denied
npm can’t write to a directory — usually global installs into a root-owned folder.
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
The docker CLI can’t talk to the Docker engine — it isn’t running, or your user can’t access the socket.
Linux: Permission denied
Your user (or the service user) lacks read/write/execute permission on a file, directory or one of its parents.
error: pathspec 'x' did not match any file(s) known to git

The OS refused the file operation — no permission, a directory passed to open(), or (on Windows) the file is open elsewhere.

Python read bytes that aren’t valid in the encoding it assumed (usually UTF-8).
Blue Screen: MEMORY_MANAGEMENT (Stop code 0x0000001A)

java.nio.file.AccessDeniedException: /path
The OS denied a file operation to the Java process.
npm ERR! code ENOTEMPTY — ENOTEMPTY: directory not empty, rename
npm couldn’t rename a folder in node_modules because it wasn’t empty — usually a corrupted or concurrently modified node_modules.

npm tried to write to a read-only location (read-only container filesystem, mounted volume, or system path).
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

The filesystem is mounted read-only — often because the kernel remounted it after detecting disk errors.

Node isn’t allowed to bind that port — ports below 1024 need root on Linux/macOS, and some Windows ports are reserved.
Error: spawn EACCES

A global install can’t create its command link because a file with that name already exists.
no space left on device (Docker / Linux)
The disk (or inode table) is full — Docker images, build cache, logs and volumes are common culprits.
umount: target is busy / Device or resource busy
The filesystem or device can’t be unmounted or removed because a process is still using it.
Disk quota exceeded (EDQUOT)
Your user or group has used its storage quota on this filesystem, even if the disk itself has space.
