No such device or address: '/dev/stdout'

问题

I'm executing a python script from within node using execSync like this:

execSync('python myScript.py -o "/dev/stdout"');

My script will send the result to the file specified at -o in this case /dev/stdout.

I get the error message "No such device or address: '/dev/stdout'".

If I execute the command manually from the terminal it runs fine, but not when started via node.

I'm running Ubuntu 12.04.

回答1:

When you run the command in a terminal, /dev/stdout redirects to the terminal stdout. When you spawn the python process with execSync there's no place for stdout to be redirected to.

If you read a bit further down the execsync page, it describes how to use a child process' stdout
