I tried so solve it like explained in this github issue

我试着解决它，就像这个GitHub问题中解释的那样

using

使用

$ conda update anaconda-navigator
$ conda update navigator-updater

But getting the same error.
I tried adding
-c conda-forge to all the commands
And tried using
conda update anaconda
conda upgrade anaconda

但得到了同样的错误。我尝试将-c conda-forge添加到所有命令中，并尝试使用conda更新anaconda conda升级anaconda

and getting the same error all the time.

并且总是得到相同的错误。

Here is my github issue on this

这是我在GitHub上的问题

Thanks!

谢谢!

update:
even when trying to use this to install anaconda-clean and removing anaconda, I am getting the same error when trying to install conda-clean that should help me remove anaconda from my machine

更新：即使在尝试使用它来安装Anaconda-Clean和删除Anaconda时，我也得到了相同的错误，当我尝试安装Conda-Clean时，应该可以帮助我从我的机器上删除Anaconda

The issue of Conda yielding unexpected errors across different environments is well-known. Often, the default settings clash with one's own, or if self-configured, an incorrect path may have been set in one's shell configuration file (in my case, for instance, the ~/.zshrc file).

Conda在不同环境中产生意外错误的问题是众所周知的。通常，默认设置与用户自己的设置冲突，或者如果是自行配置的，则可能是在用户的外壳配置文件中设置了不正确的路径(在我的例子中，是~/.zshc文件)。

One could meticulously analyze the causes, set the correct path, and then restart the shell (for zsh, this would be executed via zsh -l).

用户可以仔细分析原因，设置正确的路径，然后重新启动外壳(对于zsh，这将通过zsh-L执行)。

Quick solution

快速解决方案

However, if you're in a hurry and wish to make all the necessary configurations later, a more expedient solution exists on Linux-based systems; you can simply try the following:

但是，如果您很匆忙，并且希望稍后进行所有必要的配置，那么在基于Linux的系统上有一个更方便的解决方案；您可以简单地尝试以下方法：

source activate <env-name>

Understanding the issues

了解问题

Upon initializing Conda, it would also be prudent to specify the name of one's own shell, such as

在初始化conda时，指定自己的外壳的名称也是明智的，例如

conda init zsh

After restarting one's own shell (as previously mentioned, with zsh -l where -l stands for load), the command

在重新启动自己的外壳之后(如前所述，使用zsh-L，其中-L代表加载)，命令

conda activate <env-name> 

should then operate as desired.

然后应该按照预期的方式运行。

In conclusion, a brief summary:

最后，简要总结如下：

1. Initialisation

conda init <shell-name> # e.g., zsh or bash

2. Apply the changes by restarting the terminal.

If it is zsh, then

如果是zsh，那么

zsh -l

3. Create a new environment for a certain python version

conda create --name <env-name> python=3 

4. Check if the environment is already created

conda env list 

An example would be:

例如：

base                     /opt/homebrew/anaconda3
codellama             *  /opt/homebrew/anaconda3/envs/codellama
llama2                   /opt/homebrew/anaconda3/envs/llama2

The * indicates that codellama is currently active

*表示Codellama当前处于活动状态

5. Active the environment

conda activate <env-name>

This should function without any issues.

这应该可以正常运行，没有任何问题。

I had the same issue, just run

我也有同样的问题，快跑吧

conda init

Saved me after one whole hour of troubleshooting. Turns out my C:\Users\**\miniconda3\Scripts\activate and C:\Users\**\miniconda3\Scripts\deactivate weren't updated.

在进行了整整一个小时的故障排除后救了我一命。原来，我的C：\USERS\**\miniconda3\Script\Activate和C：\USERS\**\minicda3\Script\Deactive没有更新。

UPDATED ANSWER:

更新答案：

For Linux users I actually found that deleting all the lines added by conda in the .bashrc other than export PATH="/home/<user>/anaconda3/bin:$PATH"
to be the best solution for this.

对于Linux用户，我发现删除除导出路径=“/home/ /anaconda3/bin：$PATH”之外的.bashrc中由Conda添加的所有行是解决此问题的最佳解决方案。

PREVIOUS ANSWER:

上一个答案：

Not sure it's a fix for everyone, but I got around this by running /home/<user>/anaconda3/bin/conda install anaconda-clean (or wherever your conda file is stored), and from the packages this installed, the problem magically disappeared.

不确定它是否适用于所有人，但我通过运行/home/ /anaconda3/bin/conda Install anaconda-lean(或存储conda文件的任何位置)解决了这个问题，并且从这个安装的包中，问题神奇地消失了。

If that doesn't work, try doing a 'full' uninstall of anaconda (https://docs.anaconda.com/anaconda/install/uninstall/), reinstall it, then try doing what I suggested above.

如果这不起作用，试着对蟒蛇(https://docs.anaconda.com/anaconda/install/uninstall/)，重新安装一次“完全”卸载，然后试着按照我上面的建议做。

Add this on top of your bash script:

在您的bash脚本上添加以下代码：

source  ~/miniconda3/etc/profile.d/conda.sh

Functions are not exported by default to be made available in subshells. See: https://github.com/conda/conda/issues/7980

默认情况下，函数不会被导出以在子外壳中可用。请参阅：https://github.com/conda/conda/issues/7980
