Anaconda python 继续使用 2.7

我正在使用 ubuntu 16.04。我安装了蟒蛇使用bash ~/Downloads/Anaconda3-5.1.0-Linux-x86_64.sh。

然后我创建一个新环境conda create -n python35 python=3.5 anaconda

然后我激活conda activate python35。然后我通过输入启动python python，但它仍然说我正在使用python 2.7。

答案1

这是因为您的.bashrc文件中有此行。

alias python=python2.7

用以下命令删除该行：

sed -i.bak '/python=python2.7/d' ~/.bashrc

然后运行此命令：

source ~/.bashrc
