按照http://www.coin-or.org/PuLP/main/installing_pulp_at_home.html#installation的指示，我使用“从源代码安装Windows”安装了PuLP。
当我尝试在页面上运行测试时(页面上的说明:“要测试您的 PuLP 安装是否正常工作，请在python解释器中输入以下内容，并注意输出应类似。如果您还没有安装任何其他求解器以及与制浆厂捆绑在一起的CoinMP求解器，我会期望的。”)
我的结果:
根据网页，这应该是我的输出:
我在Windows 7 64位上使用Python 2.7.1，PuLP 1.4.7。
我猜这是因为与PuLP捆绑在一起的CoinMP求解器无法正常工作。我一周前才刚开始使用Python，但是我只是编程的业余爱好者。
最佳答案
Afaik您需要安装任何受支持的求解器，例如
sudo aptitude install glpk
或者
sudo aptitude install coinor-libcbc0
刚刚在(K)ubuntu 11.10上进行了测试，并得到了
