[yes|no]  >>> no    添加“export PATH=/usr/local/anconda3/bin:$PATH“ 到/etc/profile,这样所有用户都可以使用Anaconda python3.7了。    上面的.bashrc在刚才安装时添加了如下内容:    # added by Anaconda3 5.3.0 installer  # >>> conda init >>>  # !! Contents within this block are managed by 'conda init' !!  __conda_setup="$(CONDA_REPORT_ERRORS=false '/usr/local/anaconda3/bin/conda' shell.bash hook 2> /dev/null)"  if [ $? -eq 0 ]; then   eval "$__conda_setup"  else   if [ -f "/usr/local/anaconda3/etc/profile.d/conda.sh" ]; then    . "/usr/local/anaconda3/etc/profile.d/conda.sh"    CONDA_CHANGEPS1=false conda activate base   else    export PATH="/usr/local/anaconda3/bin:$PATH"   fi  fi  unset __conda_setup~/.bashrc  # <<< conda init <<<

验证安装

通过重新登陆或者执行'source ~/.bashrc"加载环境变量。

  $ conda info    active environment : base   active env location : /usr/local/anaconda3     shell level : 1    user config file : /home/andrew/.condarc   populated config files :      conda version : 4.5.11   conda-build version : 3.15.1     python version : 3.7.0.final.0    base environment : /usr/local/anaconda3 (read only)     channel URLs : https://repo.anaconda.com/pkgs/main/linux-64         https://repo.anaconda.com/pkgs/main/noarch         https://repo.anaconda.com/pkgs/free/linux-64         https://repo.anaconda.com/pkgs/free/noarch         https://repo.anaconda.com/pkgs/r/linux-64         https://repo.anaconda.com/pkgs/r/noarch         https://repo.anaconda.com/pkgs/pro/linux-64         https://repo.anaconda.com/pkgs/pro/noarch     package cache : /usr/local/anaconda3/pkgs         /home/andrew/.conda/pkgs    envs directories : /home/andrew/.conda/envs         /usr/local/anaconda3/envs      platform : linux-64      user-agent : conda/4.5.11 requests/2.19.1 CPython/3.7.0 Linux/4.15.0-36-generic ubuntu/18.04 glibc/2.27      UID:GID : 1000:1000      netrc file : None     offline mode : False  $ python  Python 3.7.0 (default, Jun 28 2018, 13:15:42)   [GCC 7.2.0] :: Anaconda, Inc. on linux  Type "help", "copyright", "credits" or "license" for more information.  >>>
