在 Python 3 上安装 pycairo

我正在尝试安装pycairo，但是我的符号链接将其发送到 python 2，尽管它需要 3。我该如何解决这个错误？

# ./waf build
  ./options()
The project was not configured: run "waf configure" first!
root@Archimedes:/home/archimedes/Downloads/pycairo-1.10.0# ./waf configure
  ./options()
Setting top to                           : /home/archimedes/Downloads/pycairo-1.10.0 
Setting out to                           : /home/archimedes/Downloads/pycairo-1.10.0/build_directory 
  ./configure()
Checking for 'gcc' (c compiler)          : ok 
Checking for program python              : /usr/bin/python 
Checking for python version              : (2, 7, 3, 'final', 0) 
The python version is too old, expecting (3, 1, 0)
(complete log in /home/archimedes/Downloads/pycairo-1.10.0/build_directory/config.log)

当检查 python 时，有没有办法将它发送到/usr/bin/python3而不是(符号链接)？谢谢！/usr/bin/python

将环境变量设置$PYTHON为要使用的二进制文件的路径，例如

export PYTHON=/usr/bin/python3
./waf configure
