bash 默认情况下，如何防止 Conda 激活基础环境？

How do I prevent Conda from activating the base environment by default?

提问by DryLabRebel

I recently installed anaconda2 on my Mac. By default Conda is configured to activate the base environment when I open a fresh terminal session.

我最近在 Mac 上安装了 anaconda2。默认情况下，Conda 配置为在我打开新的终端会话时激活基本环境。

I want access to the Conda commands (i.e. I want the path to Conda added to my $PATH which Conda does when initialised so that's fine).

我想访问 Conda 命令（即，我希望将 Conda 的路径添加到我的 $PATH 中，Conda 在初始化时会这样做，这样很好）。

But I don't ordinarily program in python, and I don't want Conda to activate an environment by default.

但是我一般不会用python编程，也不希望Conda默认激活一个环境。

When first executing conda initfrom the prompt, Conda adds the following to my .bash_profile:

首次conda init从提示执行时，Conda 将以下内容添加到 my .bash_profile：

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/Users/geoff/anaconda2/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
if [ -f "/Users/geoff/anaconda2/etc/profile.d/conda.sh" ]; then
    . "/Users/geoff/anaconda2/etc/profile.d/conda.sh"
else
    export PATH="/Users/geoff/anaconda2/bin:$PATH"
fi
# fi
unset __conda_setup
# <<< conda initialize <<<

If I comment out the whole block, then I can't activate any Conda environments.

如果我注释掉整个块，那么我将无法激活任何 Conda 环境。

I tried to comment out the whole block except for

我试图注释掉整个块，除了

export PATH="/Users/geoff/anaconda2/bin:$PATH"

But then when I started a new session and tried to activate an environment, I got this error message:

但是当我开始一个新的会话并尝试激活一个环境时，我收到了这个错误消息：

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.

This question(and others like it) are helpful, but doesn't ultimately answer my question and is more suited for linux users.

这个问题（以及其他类似问题）很有帮助，但最终并没有回答我的问题，更适合 linux 用户。

For clarification, I'm not asking to remove the (base)from my $PS1I'm asking for Conda not to activate base when I open a terminal session.

为了澄清起见，我不是要求(base)从我$PS1要求 Conda 在打开终端会话时不要激活 base 中删除。

I have conda 4.6 with a similar block of code that was added by conda. In my case, there's a conda configuration setting to disable the automatic base activation:

我有 conda 4.6，其中包含由 conda 添加的类似代码块。就我而言，有一个 conda 配置设置来禁用自动基本激活：

conda config --set auto_activate_base false

The first time you run it, it'll create a ./condarcin your home directory with that setting to override the default.

第一次运行它时，它会./condarc在您的主目录中创建一个使用该设置覆盖默认值的设置。

This wouldn't de-clutter your .bash_profilebut it's a cleaner solution without manual editing that section that conda manages.

这不会使您的内容.bash_profile变得混乱，但它是一种更简洁的解决方案，无需手动编辑 conda 管理的部分。

The answer depends a little bit on the version of condathat you have installed. For versions of conda >= 4.4, it should be enough to deactivatethe conda environment after the initialization, so add

答案在一定程度上取决于conda您安装的版本。conda>=4.4的版本，deactivate初始化后的conda环境应该就够了，所以添加

conda deactivate

So in the end I found that if I commented out the Conda initialisation block like so:

所以最后我发现，如果我像这样注释掉 Conda 初始化块：

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
# __conda_setup="$('/Users/geoff/anaconda2/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
# if [ $? -eq 0 ]; then
    # eval "$__conda_setup"
# else
if [ -f "/Users/geoff/anaconda2/etc/profile.d/conda.sh" ]; then
    . "/Users/geoff/anaconda2/etc/profile.d/conda.sh"
else
    export PATH="/Users/geoff/anaconda2/bin:$PATH"
fi
# fi
# unset __conda_setup
# <<< conda initialize <<<

It works exactly how I want. That is, Conda is available to activate an environment if I want, but doesn't activate by default.

它完全按照我想要的方式工作。也就是说，如果需要，Conda 可用于激活环境，但默认情况下不会激活。

There're 3 ways to achieve this after conda4.6. (The last method has the highest priority.)

在conda4.6之后有 3 种方法可以实现这一点。（最后一种方法具有最高优先级。）

1. Use sub-command conda configto change the setting.

   conda config --set auto_activate_base false
   

2. In fact, the former conda configsub-command is changing configuration file .condarc. We can modify .condarcdirectly. Add following content into .condarcunder your home directory,

   # auto_activate_base (bool)
   #   Automatically activate the base environment during shell
   #   initialization. for `conda init`
   auto_activate_base: false
   

3. Set environment variable CONDA_AUTO_ACTIVATE_BASEin the shell's init file. (.bashrcfor bash, .zshrcfor zsh)

   CONDA_AUTO_ACTIVATE_BASE=false
   

   To convert from the condarcfile-based configuration parameter name to the environment variable parameter name, make the name all uppercaseand prependCONDA_. For example, conda's always_yesconfiguration parameter can be specified using a CONDA_ALWAYS_YESenvironment variable.

   The environment settings take precedenceover corresponding settings in .condarcfile.

1. 使用子命令conda config更改设置。

   conda config --set auto_activate_base false
   

2. 实际上，前一个conda config子命令正在更改配置文件.condarc. 我们可以.condarc直接修改。将以下内容添加到.condarc您的主目录下，

   # auto_activate_base (bool)
   #   Automatically activate the base environment during shell
   #   initialization. for `conda init`
   auto_activate_base: false
   

3. CONDA_AUTO_ACTIVATE_BASE在 shell 的 init 文件中设置环境变量。（.bashrc对于 bash，.zshrc对于 zsh）

   CONDA_AUTO_ACTIVATE_BASE=false
   

   要将condarc基于文件的配置参数名称转换为环境变量参数名称，请将名称全部设为大写并在前面加上CONDA_。例如，always_yes可以使用CONDA_ALWAYS_YES环境变量指定conda 的配置参数。

   环境设置优先于.condarc文件中的相应设置。

If you want to keep your bashrc simple, you can remove all the conda initgenerated clutter, and keep only a single line:

如果你想保持你的 bashrc 简单，你可以删除所有conda init生成的混乱，只保留一行：

. "/Users/geoff/anaconda2/etc/profile.d/conda.sh"

See Recommended change to enable conda in your shell.

请参阅在 shell 中启用 conda 的推荐更改。

This will make the conda command available without activating the base environment.

这将使 conda 命令可用而无需激活基本环境。

If you want to use your bashrc on other systems where conda is not installed in the same path, you can keep the if/filines as well to avoid error messages, i.e.:

如果要在 conda 未安装在同一路径中的其他系统上使用 bashrc，也可以保留if/fi行以避免错误消息，即：

if [ -f "/Users/geoff/anaconda2/etc/profile.d/conda.sh" ]; then
    . "/Users/geoff/anaconda2/etc/profile.d/conda.sh"
fi

I faced the same problem. Initially I deleted the .bash_profile but this is not the right way. After installing anaconda it is showing the instructions clearly for this problem. Please check the image for solution provided by Anaconda
