问题 I am trying to use the library matplotlib, but can't get it to work with python3. The python 2.7.3 interpreter I have finds it without a problem though. What steps do I need to take for python3 to have access to this library? 回答1: To handle your Python packages, I suggest you rather use pip than your OS package manager. To install pip, just follow the instructions. wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py python ez_setup.py wget https://raw.github.com/pypa/pip

问题 I recently started using Ubuntu 12.04 and I found it very cool and easy to use for web development, but I have a problem with FONTS! Why do they look so ugly in Ubuntu? If you check a website in Firefox Ubuntu and one in Firefox Windows 7 you realize that on Windows looks better every time. Even with ttf-mscorefonts installed will look ugly. My question is how is your workflow when you develop a web app in Ubuntu knowing that the font you are using will look different on Windows. Do you

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.

问题 I'm using Ubuntu 12.04 and the binary I'm trying to run needs glibc2.16, I tried updating glibc by using apt-get install libc6 but only glibc2.15 got installed , can someone suggest me how to get glibc 2.16 in my machine.
