文章详细记录了Miniconda3在Linux系统的安装过程，包括选择安装路径、确认安装、初始化conda以及配置环境变量。安装完成后，提到了conda命令未找到的问题，解决办法是通过指定路径执行源激活。此外，还讨论了conda环境管理和包缓存路径的设置，以及处理磁盘空间不足导致的错误。

安装&start up

==============================================
https://conda.io/projects/conda/en/latest/user-guide/install/linux.html


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

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

[/root/miniconda3] >>> /data/miniconda3
PREFIX=/data/miniconda3

==> For changes to take effect, close and re-open your current shell. <==

If you'd prefer that conda's base environment not be activated on startup, 
   set the auto_activate_base parameter to false: 

conda config --set auto_activate_base false

Thank you for installing Miniconda3!

conda: command not found
去到 /data/miniconda3/bin 执行 source activate
./conda init
source ~/.bashrc

envs_dirs:
  - /data/miniconda3/envs

pkgs_dirs:
  - /data/miniconda3/pkgs

如果报错NoWritablePkgsDirError: No writeable pkgs directories configured.需要对文件夹进行权限的分配

pip install遇到"No space left on device"

原因：linux出现tmp空间满的情况解决
可用pip config set global.cache-dir ./tmpbak/ 或 pip install … --no-cache-dir
