第一个问题，我对Python很陌生。使用Ubuntu 18.04，我已经设置为从实验室运行新程序。我很难让编译器（例如gcc）在安装中工作。我终于安装了所有东西，但是无法打开jupyter笔记本。我已经尝试了1.5天，以解决Google上的所有问题。第一个错误是：
/home/sarah/anaconda3/envs/celloracle_env/compiler_compat/ld: cannot find -lpthread
/home/sarah/anaconda3/envs/celloracle_env/compiler_compat/ld: cannot find -lc
collect2: error: ld returned 1 exit status

我已确保安装了pthread和c，但无济于事。任何帮助将不胜感激。以下是完整错误的图片。谢谢！ enter image description here
