报错：
ondaIOError: Missing write permissions in: /usr/local/anaconda3
#
# You don't appear to have the necessary permissions to install packages
# into the install area '/usr/local/anaconda3'.
# However you can clone this environment into your home directory and
# then make changes to it.
# This may be done using the command:
#
# $ conda create -n my_root --clone="/usr/local/anaconda3"
例子：
问题在于 anaconda所在文件夹只有root 才有权限，而 sudo 对于conda没用，
解决方案是修改文件夹权限给当前用户
sudo chown -R usr foldername
比如我的用户名是 adrianna, anaconda 的安装目录是/usr/local/anaconda3：
adrianna@adrianna-ubuntu:~$ sudo chown -R adrianna /usr/local/anaconda3
