+This issue commonly arises when building for Linux and using a conda environment, due to some libraries in the conda environment having compilation parameter problems. The solution is to not use conda, or to individually locate the problematic library within conda and replace it with the system's version or simply delete it (the system will then locate the necessary library).

+一般在为 Linux 构建时并且使用 conda 环境时容易出现，conda 环境中的一些库编译参数问题，解决方法就是不用 conda 即可， 或者单独找到 conda 中的那个库，替换成系统的或者直接删掉（会从系统找）
