如何才能正确找到python3.3库？

Answer 1

我遇到了与python 3.4相同的问题。

这是因为waf试图用python执行python3.4-config而python3.4-config是shell脚本。

事实上，单独启动python3.4-config非常有效。

    [dusserm@l92-ci-e pycairo-1.10.0]$ python3 /Produits/publics/x86_64.Linux.RH6/python/3.4.1/bin/python3.4-config --includes
      File "/Produits/publics/x86_64.Linux.RH6/python/3.4.1/bin/python3.4-config", line 7
        echo "Usage: $0 --prefix|--exec-prefix|--includes|--libs|--cflags|--ldflags|--extension-suffix|--help|--abiflags|--configdir"
                                                                                                                                    ^

问题来自waf没有正确使用python3.X-config。

我找到的解决方法是直接修改waf脚本解压缩的隐藏目录（在我的例子中是.waf3-1.6.4-e3c1e08604b18a10567cfcd2d02eb6e6）。转到这个目录，更改文件waflib / Tools / python.py，直接调用python3.X-config而不用python。

我遇到了同样的问题。我通过添加系统变量来修复：
[＆＃39; /usr/local/bin/python3.4' ;,＆＃39; /usr/local/bin/python3.4-config'，＆＃39; - 包括＆＃39;]返回1

export PYTHON_CONFIG="/usr/local/lib/python3.4/config-3.4m/python-config.py"

waf构建系统找不到python库
