用 conda 虚拟环境跑代码，import scipy 时报错：

ImportError: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /data/itom/miniconda3/envs/cu116_pt1131/lib/python3.9/site-packages/scipy/spatial/_ckdtree.cpython-39-x86_64-linux-gnu.so)

参考 [1]，一种解法是把所用的 conda 虚拟环境的 lib/ 加入到 LD_LIBRARY_PATH。为自动导入，可在 ~/.bashrc 中加入：

• 假设 miniconda3 的安装路径是 ~/miniconda3/

# ~/.bashrc 内
if [ -d $HOME/miniconda3/envs ]; thenld_lib_path=""for d in `ls $HOME/miniconda3/envs`; doif [ -z $ld_lib_path ]; thenld_lib_path=$HOME/miniconda3/envs/$d/libelseld_lib_path=$ld_lib_path:$$HOME/miniconda3/envs/$d/libfidoneif [ ! -z $ld_lib_path ]; thenif [ -z $LD_LIBRARY_PATH ]; thenexport LD_LIBRARY_PATH=$ld_lib_pathelseexport LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ld_lib_pathfifi
