推荐答案

如果您下载了二进制文件，那么您只需确保 ipopt 可执行文件位于您的 PATH 环境变量中.如果您尝试从源代码安装，则应按照此处的说明进行操作.您的最后一个选择是使用 anaconda 使用以下命令安装 ipopt 二进制文件:

If you downloaded a binary then you just have to make sure that the ipopt executable is in your PATH environment variable. If you are trying to install from source code you should follow the instructions here. Your last option is to use anaconda to install an ipopt binary using the command:

conda install -q -y --channel cachemeorg ipopt_bin

我认为 conda 安装了旧版本的 ipopt，所以请注意.

I think conda installs an old version of ipopt so be aware.

当您在终端窗口中键入 ipopt 并获得以下输出时，您将知道通过这些安装中的任何一个安装正确:

With any of these installations you will know it is installed correctly when you type ipopt in a terminal window and get the following output:

No stub!
usage: ipopt [options] stub [-AMPL] [<assignment> ...]

Options:
    --  {end of options}
    -=  {show name= possibilities}
    -?  {show usage}
    -e  {suppress echoing of assignments}
    -s  {write .sol file (without -AMPL)}
    -v  {just show version}
