没找到解决方法。遂放弃。

conda 安装

1
conda install -y -c conda-forge openbabel

安装还挺快。接下来绑定python
从pypi上下载openbabel的源码包（pip install直接安装会报错），下载地址https://pypi.org/project/openbabel/#files
解压后安装命令如下

1

5
cd openbabel-3.1.1.1
# -I 指定conda安装openbabel的include的路径，-L 指定conda安装openbabel的lib的路径
python setup.py build_ext -I$CURR_DIR/envs/Sdocking/include/openbabel3/ -L$CURR_DIR/envs/Sdocking/lib/openbabel/3.1.0
# --prefix指定安装路径，最好指定下，默认会安装到当前目录，后续执行 import openbabel的时候会报错找不到
python setup.py install --prefix=$CURR_DIR/envs/Sdocking/lib/python3.7/site-packages

安装完确认是否安装成功

1
python -c 'import openbabel'
