编译Substrate node-template执行cargo build --release时出现磁盘空间不足错误求助

Hey there, sorry you're stuck with this disk space hiccup while compiling the Substrate node-template. Let's work through some practical fixes to get your build back up and running:

1. First, verify your disk is actually full #

Run this command to check available space across all your system's partitions:

df -h

Look at the /home row (since your project lives in ~/project/) — if the Use% column is hovering near 100%, that's exactly why you're hitting this error.

2. Clean up Cargo's build artifacts #

Cargo piles up tons of intermediate build files in the target directory. Clear your project's local build cache first:

cargo clean

If you want to free up even more space, install the cargo-cache tool to prune global unused dependencies and old build artifacts:

cargo install cargo-cache
cargo cache --autoclean

This will wipe out redundant files you don't need anymore.

3. Clear system-level junk from Kali #

Free up space by removing unused packages and cached installation files:

sudo apt autoremove --purge
sudo apt clean

You can also safely delete temporary files in /tmp (these are usually auto-cleaned, but manual cleanup gives an immediate boost):

sudo rm -rf /tmp/*

4. Redirect the target directory to a partition with more space #

If your /home partition is permanently low on space, you can point Cargo's build output to another drive/partition using a symlink:

1. Create a directory on the partition with free space (e.g., /data):

   sudo mkdir -p /data/substrate-target
   sudo chown $USER:$USER /data/substrate-target
   

2. Delete the existing target folder in your project:

   rm -rf ~/project/substrate-node-template/target
   

3. Create a symlink linking your project to the new directory:

   ln -s /data/substrate-target ~/project/substrate-node-template/target
   

Now when you run cargo build --release, all build files will go to the space-rich location instead.

5. Hunt down and delete large, unnecessary files #

Use the ncdu tool to scan your /home directory and spot big files you can get rid of:

1. Install it first:

   sudo apt install ncdu
   

2. Run it on your home directory:

   ncdu ~/
   

Navigate through the results to find old archives, unused projects, or other large files taking up space, then delete them to free up room.
