我喜欢拥有极小的base conda环境。我意外地在这个环境中安装了一堆包，所以我尝试删除它们：

我按照conda: remove all installed packages from base/root environment的建议运行了以下命令：conda install --revision 0 -n base

但是，当我运行以下脚本重新安装要点时：

代码语言：javascript
运行
复制
conda install -c conda-forge wget rsync pv ipython jupyter jupyterlab pandas numpy biopython r-recommended python=3 -y

conda install -c bioconda pullseq samtools bbmap hmmer ncbi-genome-download -y

它坏了，我甚至无法访问我的conda。

代码语言：javascript
运行
复制
-bash-4.1$ which conda
/usr/local/devel/ANNOTATION/jespinoz/anaconda3/condabin/conda
-bash-4.1$ conda -h
Traceback (most recent call last):
  File "/usr/local/devel/ANNOTATION/jespinoz/anaconda3/bin/conda", line 12, in <module>
    from conda.cli import main
ModuleNotFoundError: No module named 'conda'

有几篇文章指出，这与我的PYTHONPATH和PYTHONHOME环境变量有关，但我没有这些设置：

代码语言：javascript
运行
复制
-bash-4.1$ echo $PYTHONHOME

-bash-4.1$ echo $PYTHONPATH

我认为这是因为我的默认python版本现在是3.8，它没有安装conda。但是，3.7确实安装了conda。

代码语言：javascript
运行
复制
-bash-4.1$ ls -l /usr/local/devel/ANNOTATION/jespinoz/anaconda3/lib/python3.8/site-packages/  | grep "conda"
-bash-4.1$ ls -l /usr/local/devel/ANNOTATION/jespinoz/anaconda3/lib/python3.7/site-packages/  | grep "conda"

drwxr-xr-x  2 jespinoz tigr     188 Dec  9 14:49 conda_verify-3.1.1-py3.7.egg-info

我能用这个来弥补坏掉的设置吗？

我差点就开始工作了：

第一个符号链接从python3.7站点到3.8的conda二进制文件

代码语言：javascript
运行
复制
-bash-4.1$ ln -s /usr/local/devel/ANNOTATION/jespinoz/anaconda3/lib/python3.7/site-packages/cond* /usr/local/devel/ANNOTATION/jespinoz/anaconda3/lib/python3.8/site-packages/

当您尝试还原python3.7时，它不起作用：

代码语言：javascript
运行
复制
-bash-4.1$ conda install python=3.7
Traceback (most recent call last):
  File "/usr/local/devel/ANNOTATION/jespinoz/anaconda3/lib/python3.8/site-packages/conda/common/serialize.py", line 19, in get_yaml

During handling of the above exception, another exception occurred:

    import ruamel.yaml as yaml
ModuleNotFoundError: No module named 'ruamel'

During handling of the above exception, another exception occurred:

    from .serialize import yaml_load

    raise ImportError("No yaml library available.\n"
ImportError: No yaml library available.
To proceed, conda install ruamel_yaml

当然，您不能真正做conda install ruamel_yaml，因为这太简单了。而是使用pip

代码语言：javascript
运行
复制
-bash-4.1$ pip install ruamel_yaml
Collecting ruamel_yaml

然后我尝试了以下几点：

代码语言：javascript
运行
复制
-bash-4.1$ conda install python=3.7 -n base

我修好了。我试着下载最新的安装，然后运行-u进行升级(这花费了很长时间)，但没有成功。

我最后所做的是使用我的同事安装conda：

代码语言：javascript
运行
复制
source /path/to/their/conda/activate /path/to/my/anaconda3

然后我设置了我的~/.condarc，这样它就知道我的pkgs和环境应该放在哪里了(我们的主目录中有一个有限的空间，所以如果我不这样做，它就会崩溃)

代码语言：javascript
运行
复制
(/usr/local/devel/ANNOTATION/jespinoz/anaconda3) -bash-4.1$ cat ~/.condarc
channels:
  - bioconda
  - conda-forge
  - defaults
  - etetoolkit
  - r
channel_priority: true
report_errors: true

envs_dirs:
  - /usr/local/devel/ANNOTATION/jespinoz/anaconda3/envs/

pkgs_dirs:
  - /usr/local/devel/ANNOTATION/jespinoz/anaconda3/pkgs/

在那之后，我做了以下工作：

代码语言：javascript
运行
复制
conda install python=3.7 -y

不过，我收到了以下错误/警告：

代码语言：javascript
运行
复制
Executing transaction: / Traceback (most recent call last):
  File "/usr/local/devel/ANNOTATION/jespinoz/anaconda3/bin/jupyter-nbextension", line 7, in <module>
    from notebook.nbextensions import main
ModuleNotFoundError: No module named 'notebook'

WARNING conda.core.link:run_script(1098): pre-unlink script failed for package conda-forge::widgetsnbextension-3.5.1-py38_0
consider notifying the package maintainer
| Enabling notebook extension jupyter-js-widgets/extension...
      - Validating: OK

最后还是起作用了。

现在，由于所有的包冲突，我正在运行conda update --all。希望它不会再次破坏我的环境。
