当进入Ubuntu环境时，调用conda info --envs 命令查看已有conda环境时，出现以下错误。

No report sent. To permanently opt-out, use

通过报错信息得知，错误的点存在以下两个：

关于ruamel.yaml的调用错误

AttributeError: 
    "load()" has been removed, use
    
      yaml = YAML(typ='rt')
      yaml.load(...)
    
    and register any classes that you use, or check the tag attribute on the loaded data,
    instead of file "/home/star/envs/lib/python3.7/site-packages/conda/common/serialize.py", line 54
    
        return yaml.load(string, Loader=yaml.RoundTripLoader, version="1.2")

conda命令发生预期之外的错误

An unexpected error has occurred. Conda has prepared the above report

另外，日常正确的加载情况应该如下，直接激活conda的base环境，如下所示。但是报错的时候并没有(base)。

(base) star@b404-3090:~$

2. 解决办法

注：我的conda安装目录是`/home/star/envs` 请自行比对

第一步：通过以下命令检查conda相关信息

export

返回信息如下所示：

(base) star@b404-3090:~$ export
declare -x CONDA_DEFAULT_ENV="base"
declare -x CONDA_EXE="/home/star/envs/bin/conda"
declare -x CONDA_HOME="/home/star/envs"
declare -x CONDA_PREFIX="/home/star/envs"
declare -x CONDA_PROMPT_MODIFIER="(base) "
declare -x CONDA_PYTHON="/home/star/envs/bin/python"
declare -x CONDA_PYTHON_EXE="/home/star/envs/bin/python"
declare -x CONDA_SHLVL="1"
declare -x CUDA_VISIBLE_DEVICES="0,1,2"

请确认以上有关CONDA的字段指向的路径是你conda正确安装的路径。再次强调，我的conda安装路径是/home/star/envs,请自己比对后修改以上字段。

第二步：通过以下命令修改不正确的字段

# vim 是编辑器，如果有其他的编辑器例如nano也可以使用
sudo vim /etc/profile

# 然后再/etc/profile文件中添加需要修改的内容，根据自己的实际情况
export NODE_HOME=/home/star/data/cxy/node-v18.18.0-linux-x64
export PATH=$PATH:$NODE_HOME/bin
export CONDA_HOME=/home/star/envs
export PATH=$PATH:$CONDA_HOME/bin
export CONDA_EXE=/home/star/envs/bin/conda
export PATH=$PATH:$CONDA_EXE
export CONDA_PREFIX=/home/star/envs
export PATH=$PATH:$CONDA_PREFIX
export CONDA_PYTHON=/home/star/envs/bin/python

# 修改完毕后，输入以下命令使其生效
source /etc/profile

# 使用export 再次查看更改是否生效

小插曲

我更改完环境变量后，在export命令返回的内容中是正确的，但是使用conda命令时出现

-bash: /home/star/anaconda3/bin/conda: 没有那个文件或目录

这是因为我的服务器中安装了两个anaconda，这个anaconda3是后面安装的，也许覆盖掉了之前的安装路径，但是我也找不到它具体是哪个变量绑定的，所以通过别名的方式进行修改，如果你也有一样的问题，可以尝试

# 注 envs是我最早安装的，anaconda3是后面安装的，所以这条指令的目的是使得conda指向最初的envs安装目录。
alias conda='/home/star/envs/bin/conda'

第三步: 确保文件有执行权限

# 使用以下指令添加权限
chmod +x /home/star/envs/bin/conda

第四步：检查是否存在ruamel包

# 如果看见了ruamel那就是已经有了，但是报错一般来说是没有的
conda list | grep "ruamel"

第四步：下载ruamel文件

打开链接：ruamel下载
由于服务器当前处于断网的情况，所以我是通过在本地下载之后，通过Xftp上传到服务器的。如果你的服务器连接了网络，那么你可以通过wget 或者curl命令下载

第五步：安装ruamel文件

使用mv命令将第四步下载的ruamel文件移动到conda安装目录下的bin目录中，我的是/home/star/envs/bin，请自行比对，移动完毕后，通过pip install 下载的文件名.whl命令进行安装。

第六步：查看是否安装成功

(base) star@b404-3090:~$ conda list |grep "ruamel"
ruamel.yaml               0.17.21                   <pip>
ruamel.yaml.clib          0.2.8                     <pip>
ruamel_yaml               0.15.46          py37h14c3975_0    https://repo.anaconda.com/pkgs/main

安装成功！到此，重新连接，就会发现再次进入时已经没有报错，并且初始是base环境~
