Using Node.js I get, "Error: EISDIR, read"

When ever I try to open a file I get,

events.js:72
        throw er; // Unhandled 'error' event
Error: EISDIR, read

This error is simple,

cd /tmp
mkdir dir
node -e "var fs = require('fs'); fs.createReadStream( 'dir' );"

EISDIR means that the target of the operation is a directory in reality but that the expected filetype of the target is something other than a directory.

EISDIR error occurs when you try to open a file, but the path given is a directory.

You can fix this by checking if is it directory-

if (fs.lstatSync(filePath).isDirectory()) {
  return;
}

For more reference see docs here.

Just came across this error and in my case it was due having used bower link previously to link to local sources which then creates a symlink in the directory. Once I've bower unlinked all the components, it worked again as expected.

Hope this might help someone.

You might get lucky checking for such error codes by running something like:

grep EISDIR -r /usr/include

When I do this, I get a line that says:

/usr/include/uv.h:  XX(EISDIR, "illegal operation on a directory")
