（接下来全是这样子重复
换一个文件尝试，下载SRR11940382，也报出来这个
考虑是不是之前sratoolkit的路径设置的错误，尝试了各种而样的，都列在下边（刚接触linux系统第二天,疯狂试错见笑了）
echo 'export export PATH=$PATH:/root/sratoolkit/sratoolkit.2.10.9-ubuntu64/bin' >> ~/.bash_profile
echo 'export export PATH=$HOME:/root/sratoolkit/sratoolkit.2.10.9-ubuntu64/bin' >> ~/.bash_profile
echo 'export export PATH=$PATH:/sratoolkit/sratoolkit.2.10.9-ubuntu64/bin' >> ~/.bash_profile
echo 'export export PATH=$HOME:/sratoolkit/sratoolkit.2.10.9-ubuntu64/bin' >> ~/.bash_profile
然后安装放置sratoolkit的地址是这个：/root/sratoolkit/
