Question

我尝试安装ipopt槽pip install ipopt

这是我的错误：

    Collecting ipopt

ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

命令pkg-config --variable pc_path pkg-config给出：

/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/lib/pkgconfig:/usr/local/Homebrew/Library/Homebrew/os/mac/pkgconfig/10.15

做到了这一点（但我认为链接很奇怪），但没有解决问题

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/lib/pkgconfig:/usr/local/Homebrew/Library/Homebrew/os/mac/pkgconfig/10.15

您必须执行以下命令：

sudo apt-get install gcc g ++ gfortran git patch wget pkg-config liblapack-dev libmetis-dev

PKG_CONFIG_PATH环境变量（安装ipopt错误）
