Question

我正在尝试安装pyglpk-0.3以与cobrapie一起使用，它是matlab眼镜蛇工具箱的python版本。每次我开始安装时，都会出现以下错误:(其中一部分）

这是上述c文件的一部分：

static PyObject* Environment_getblocks_peak(EnvironmentObject *self,
                       void *closure) {
  int cpeak;
  glp_mem_usage(NULL, &cpeak, NULL, NULL);
  return PyInt_FromLong(cpeak);
}

#if GLPK_VERSION(4,28)
#define GLP_LONG glp_long
#else
#define GLP_LONG glp_ulong
#endif

static PyObject* long2py(GLP_LONG l) {
  if ((l.hi==0 && l.lo>=0) || (l.hi==-1 && l.lo<0))
    return PyInt_FromLong(l.lo);
  PY_LONG_LONG ll = l.hi;
  ll <<= 32;
  ll |= (unsigned int)l.lo;
  return PyLong_FromLongLong(ll);
}

static PyObject* Environment_getbytes(EnvironmentObject *self,void *closure) {
  GLP_LONG b;
  glp_mem_usage(NULL, NULL, &b, NULL);
  return long2py(b);
}

我想念安装的东西吗？我使用Python 2.7.5 | Anaconda 1.6.1（x86_64）|和glpk @ 4.48_0（活动）与osx 10.8.4

Answer 1

对我来说，我要做的就是将glpk降级到4.39，因为以后的版本会遇到glp_long问题。

Answer 2

有几个人在github上克隆了pyglpk代码并更新了它以使用最新版本的glpk。我一直在使用https://github.com/bradfordboyle/pyglpk并且知道它适用于glpk-4.61

未知类型名称'glp_long'（mac osx python，pyglpk）
