使用conda安装kofamscan之后，在运行时发现出了一些问题。

在对应的kofamscan github 有提交的一个issues也有类似的问题，不过按照那个人的方法并没有解决。
应该是环境出了问题，后面检查了一些依赖的软件，ruby, hmmscan, parallel这些软件，发现又有新的问题了。
perl: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory
有新错误就好办，重新在当前的kofamscan环境中安装libnsl，安装完成后还是不行。根本找不到libnsl.so.1，不过找到了libnsl.so, libnsl.so.3和libnsl.so.3.0.0其实前两者都是连接，指向最后一个文件。同样也可以尝试使用软连接创建一个libnsl.so.1。完成后所有的就可以了。
