问题 I haven't used my python/virtual environments in a while, but I do have virtualenvironment wrapper installed also.

What does this shell test achieve

由 独自空忆成欢 提交于 2021-02-05 09:25:32
问题 I have a very simple question that I can't answer. In shell, what would this command do: test -d $VIRTUAL_ENV || virtualenv $VIRTUAL_ENV It seems like it tests if the virtualenv directory exists, but I dont understand what if does with that information.

If not, it will run virtualenv $VIRTUAL_ENV . Other

问题 Here's my problem. I can't install MatPlotLib both via pip and from source (Matplotlib installation on Mavericks). I tried brew install matplotlib and the installation successfully ended. However, it installed MatPlotLib globally and not inside the currently activated VirtualEnv. Is it possible to tell brew to install a package inside the current VirtualEnv? 回答1: I help maintain the homebrew-python tap. This is not and will not be supported and there probably isn't an easy way to do it. This
