修改TMPDIR仍触发Errno 28设备无剩余空间问题求助

Your root partition (/) is nearly full (99% used), and while redirecting TMPDIR to /media/sd makes sense for temporary files, Conda has a few other critical storage spots that are still tied to your cramped root drive. Let’s break down the likely issues and how to fix them:

1. Conda’s Package Cache Is Still Clogging the Root Partition #

By default, Conda stores downloaded packages in ~/.conda/pkgs — which lives on your root partition (/) since your home folder is part of /dev/root. Even if you set TMPDIR, Conda will first download packages to this cache, filling up your root drive before it ever touches the temporary directory.

Fixes: #

• Clear existing cache immediately: Free up space by deleting unused packages and cached files:

  conda clean -a
  

• Move the cache to /media/sd: Redirect Conda’s package storage to your spacious SD partition:

  # Create a dedicated cache folder on the SD partition
  mkdir -p /media/sd/conda_pkgs
  # Tell Conda to use this new location for packages
  conda config --add pkgs_dirs /media/sd/conda_pkgs
  

2. Your Conda Virtual Environment Lives on the Root Partition #

If your virtual environment was created in the default location (like ~/miniconda3/envs or ~/.conda/envs), it’s still residing on the root partition. Installing Bokeh requires writing files directly to the environment directory — which will fail if / is full, regardless of your TMPDIR setting.

Fixes: #

• Create a new environment on /media/sd: Install Bokeh directly into an environment on the SD partition:

  conda create --prefix /media/sd/my_bokeh_env bokeh
  

• Migrate an existing environment: If you want to keep your current setup, export it and recreate it on the SD partition:

  # Export your environment configuration to a YAML file
  conda env export > environment.yml
  # Recreate the environment in the new location
  conda env create --prefix /media/sd/my_bokeh_env -f environment.yml
  

3. Conda Isn’t Recognizing Your TMPDIR Setting #

Sometimes Conda ignores the system’s TMPDIR variable and uses its own configured temporary directory instead.

Fixes: #

• Check Conda’s current tmp_dir configuration:

  conda config --show tmp_dir
  

• Set Conda’s tmp_dir to /media/sd:

  # Create a temporary directory on the SD partition
  mkdir -p /media/sd/conda_tmp
  # Configure Conda to use this directory for temp files
  conda config --set tmp_dir /media/sd/conda_tmp
  

• Or specify TMPDIR inline when running Conda:

  TMPDIR=/media/sd/conda_tmp conda install bokeh
  

Quick Checks to Confirm Fixes #

• Verify TMPDIR is set correctly in your terminal:

  echo $TMPDIR
  

• Ensure Conda has write permissions for the new directories on /media/sd:

  ls -ld /media/sd/conda_pkgs /media/sd/conda_tmp
