pip install matplotlib:“无pkg-config"； [英] pip install matplotlib: "no pkg-config"

问题描述

当我运行 pip install matplotlib (在virtualenv内)时，输出的第一行是:

When I run pip install matplotlib (within a virtualenv), the first lines of output are:

Downloading/unpacking matplotlib
  Running setup.py egg_info for package matplotlib
    basedirlist is: ['/usr/local/', '/usr', '/usr/X11', '/opt/local']
    ============================================================================
    BUILDING MATPLOTLIB

                     Cairo: no

注意

1. 无pkg-config"和
2. 缺少的Qt库.

首先，与上面的输出相反，pkg-config is 实际上已安装并在 PATH 上:

First, contrary to what the output above says, pkg-config is in fact installed and on the PATH:

% pkg-config --version
0.27.1
% which pkg-config
/usr/local/bin/pkg-config

第二， qt 在找到 freetype 和 libpng 的同一目录中可用:

Second, qt is available in the same directory where freetype and libpng were found:

% ls -l /usr/local/opt/{freetype,libpng,qt} | cut -c43-
/usr/local/opt/freetype -> ../Cellar/freetype/2.4.10/
/usr/local/opt/libpng -> ../Cellar/libpng/1.5.13/
/usr/local/opt/qt -> ../Cellar/qt/4.8.4/

我的问题分为三个部分:

My question has three parts:

1. pip在何处安装matplotlib 会得到该 basedirlist (上面输出的第三行)?
2. 为了使 pip install matplotlib 能够找到 pkg-config ，我该怎么做?
3. 我必须做些什么才能使 pip install matplotlib 找到 qt ?

1. Where does pip install matplotlib get that basedirlist (3rd line of the output above)?
2. What must I do differently so that pip install matplotlib will find pkg-config?
3. What must I do differently so that pip install matplotlib will find qt?

推荐答案

在 Mac OS 上:我使用 which pkg-config 来检查安装.如果没有，请使用brew安装，并且可以正常工作:

On Mac OS: I use which pkg-config to check installation. If not, use brew to install and it works:

brew install pkg-config
