当我尝试使用以下命令行将pytorch版本更新到0.4时

conda install pytorch=0.4.0 -c pytorch

我得到以下错误：

我在网上看到我应该使用chown功能，但我不知道如何使用它。我该怎么办？你知道吗

除非有多个用户使用同一个anaconda环境，否则您应该已将anaconda安装到主目录，但这里有一个快速修复程序，终端类型：

sudo chown -R USERNAME /anaconda

然后更新你的conda，这个命令将把根目录下的anaconda目录的所有权转移给你的用户。如果多个用户需要使用相同的anaconda环境，请执行以下步骤

#  create a new user group  
sudo groupadd anacondausers
#  add all users to group
sudo usermod -a -G anacondausers USER1
sudo usermod -a -G anacondausers USER2
#  make your group owner of folder
sudo chown -R :anacondausers /anaconda
