The codes I've tried: #!/usr/bin/env python # coding: utf8 import subprocess import os #os.environ.setdefault("XAUTHORITY", "/home/guillaume" + "/.Xauthority") #os.environ.setdefault('DISPLAY', ':0.0') # do not work #os.environ['DISPLAY'] = ':0.0' # do not work print = os.environ

问题 This question already has answers here : How to access environment variable values? (10 answers) Closed 6 years ago . I'm new to Python and would like reproduce a convenience I used when working in Perl. When calling a Perl script I usually set some $ENV variables (like VERBOSE, DEVELOP and DEBUG). Inside the called script I recover their values using my $verbose=$ENV{VERBOSE}; my $develop=$ENV{DEVELOP}; my $debug=$ENV{DEBUG}; This allow print stmts conditional on these variables. Can I do

问题 What I'm trying to do is as follows: (let ((pj-path (concat src haxe-project-generator))) (when (file-exists-p pj-path) (shell-command (concat "env " (haxe-build-env-vars <more arguments>) (format "'%s'" pj-path))))) I.e. I want to call a program pj-path in environment populated with some variables. In the line (format "'%s'" pj-path) I tried single and double quotes - but env doesn't do path expansion and if it is quoted, it will treat it as a string, not finding the file. However, if it is

问题 So, I made a simply ruby script, #!/usr/bin/env ruby puts "Hello!" When I try to run it in terminal it doesn't put "Hello!" on the screen. I have tried entering chmod +x test.rb ( test.rb is the name of my file). When I run it, it doesn't give me an error, it just doesn't display "Hello!". Any help will be much appreciated. I have looked everywhere for a possible answer, and I have found nothing so far. 回答1: I'd guess that you're trying to run it as just test like this: $ test But test is a

问题 Will there be any difference or it's just a personal choice? 回答1: #!<interpreter> <arguments> tries to run <interpreter> <arguments> to read and run the rest of the file. So #!/usr/bin/env means that there must be a program called /usr/bin/env ; #!/bin/env means that there must be a program called /bin/env . Some systems have one and not the other. In my experience, most have /usr/bin/env , so #!/usr/bin/env is more common. Unix systems will try to run <interpreter> using execve , which is
