jupyter笔记本找不到lpthread和lc

Question

这里的第一个问题，我对Python非常陌生。使用Ubuntu18.04，我在实验室里安装了一个新程序。我很难让编译器（比如gcc）在安装过程中正常工作。我终于安装了所有东西，但无法打开jupyter笔记本。为了解决这个问题，我已经在谷歌上试用了1.5天了。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

我已经确保安装了pthread和c，但是没有用。任何帮助都将不胜感激。下面是完整错误的图片。谢谢 enter image description here
