Estou tentando instalar o opencv usando o comando
conda install opencv
Este comando funcionou no meu laptop, mas estou recebendo o seguinte erro quando eu tento no meu computador desktop. Ambos os sistemas estão executando o Ubuntu 14.04

Error: Missing write permissions in: /home/ws2/anaconda2
#
# You don't appear to have the necessary permissions to install packages
# into the install area '/home/ws2/anaconda2'.
# 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=/home/ws2/anaconda2
O problema é que, de alguma forma, a pasta "anaconda2", onde o "anaconda" está instalado, foi definida como "access only", porque o proprietário da pasta "anaconda2" era "root". Agora mudei a propriedade da pasta "anaconda2" usando o comando
sudo chown -R ws2 anaconda
sudo chown -R usr foldername
Por favor, tente executar o seu comando usando sudo , assim:
sudo conda install opencv
