在更新Conda后遇到'libarchive'模块找不到的问题，尝试从Miniconda重新安装修复。下载Miniconda安装脚本，选择不初始化，进入Miniconda3/bin目录，使用其conda命令修复Anaconda3。通过安装miniconda3中的conda_package_handling、requests和urllib3等缺失包。然而，在执行修复步骤时遇到错误，无法继续。

During handling of the above exception, another exception occurred:

非常僵硬，去github上搜到相应解决方案

里面有个方法是这样：

downloaded Miniconda3-latest-Linux-x86_64.sh from https://repo.continuum.io/miniconda/
bash Miniconda3-latest-Linux-x86_64.sh
“Do you wish the installer to initialize Miniconda3 by running conda init?” NO If you choose this, I think the default environment when startup should be in miniconda3 but not the original anaconda3.
cd ~/miniconda3/bin This conda from miniconda3 should work perfectly without bugs.
Use the conda from miniconda3 to ‘heal’ your anaconda3. Like this:
./conda install --prefix ~/anaconda3/ ~/anaconda3/pkgs/conda_package_handling_XXX.tar.bz2
This should allow you to reinstall the packages that are missing in the error output of anaconda3.
In my case, I reinstall conda_package_handling, requests, and urllib3.
Try your anaconda3 conda using conda info or conda install PACKAGE.
If you can get a normal output from conda info, you should be able to revert to previous version of conda using conda install --revision. Please see: link

但是我到第四步就挂了了，显示如下：

Miniconda3 will now be installed into this location:
/Users/miniconda3

  - Press ENTER to confirm the location
  - Press CTRL-C to abort the installation
  - Or specify a different location below

[/Users/miniconda3] >>> 
PREFIX=/Users/miniconda3

好的，不晓得为啥了，我死了。
