我对让pyomo和gurobi在python中进行交互有问题。我正在运行一个优化问题，其中我使用pyomo来构建优化问题本身，然后使用gurobi来解决它。我一直在深入研究这些问题，但不幸的是，我没有成功地找到解决办法。我遇到了几个令我困惑的观察结果。它们是：

• 我能够解决gurobi从他们的网站提供的那些简单的优化问题之一。
• 可以将gurobi导入到python中，但不能从bash中输入gurobi.sh (gurobi.sh)。我得到了一个(命令未找到-错误)。另一方面，我能够使用grbgetkey命令添加许可证。这表明gurobi没有安装或路径设置不正确，但我可以将其导入python.

。

我正在运行python2.7，pyomo6.5和gurobi9.1

另外，下面是bashrc文件的外观。这是有点复杂，但我强烈地假设路径是正确的。

# User specific aliases and functions
export PATH=/usr/local/anaconda27/bin:$PATH
export LD_LIBRARY_PATH=/etc/glad-smail-liberr:$LD_LIBRARY_PATH
#export GUROBI_HOME="/opt/gurobi650/linux64"
export GUROBI_HOME="/usr/local/anaconda27"
export PATH="${PATH}:${GUROBI_HOME}/bin"
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:${GUROBI_HOME}/lib"
export GRB_LICENSE_FILE="${GUROBI_HOME}/lib/gurobi.lic"

下面，我插入了错误消息：
