China Mirror

One-stop configuration and installation for all development tools in China.

All scripts are bundled under this skill's scripts/ directory — invoked via bash, not loaded into context.

Steps

1. Determine SKILL_DIR

SKILL_DIR="<absolute path to china-mirror skill directory>"

Use the directory where this SKILL.md resides.

---

2. Identify intent: INSTALL vs CONFIGURE

Ask the user (or infer from context) which operation they need:

Intent	Signal	Action
Install tool	"安装", "没有", "install", "从零"	Run install.sh
Configure mirror	"太慢", "换源", "配置镜像", "timeout"	Run setup.sh
Both	New machine setup	Run install.sh then setup.sh

---

3a. INSTALL TOOL — download and install via Chinese mirrors

For users who don't have the tool yet or want to install a specific version:

Tool	Script	Default Mirror	Notes
Python	scripts/python/install.sh	huawei (pyenv)	Installs pyenv + Python version
Node.js	scripts/node/install.sh	npmmirror (nvm)	Installs nvm + Node.js version
Conda/Miniconda	scripts/conda/install.sh	tuna	Downloads Miniconda installer
Rust	scripts/rust/install.sh	tuna (rustup)	Sets RUSTUP_DIST_SERVER
Go	scripts/go/install.sh	tuna	Downloads Go tarball
Docker CE	sudo scripts/docker/setup.sh	tuna	Uses docker-ce apt repo mirror

Examples:

# Install Python 3.12 via Huawei Cloud pyenv mirror
bash "$SKILL_DIR/scripts/python/install.sh" -v 3.12.0

# Install Node.js LTS via npmmirror
bash "$SKILL_DIR/scripts/node/install.sh" -v lts

# Install Miniconda from TUNA
bash "$SKILL_DIR/scripts/conda/install.sh" -y

# Install Rust (stable) via TUNA rustup mirror
bash "$SKILL_DIR/scripts/rust/install.sh" -y

# Install Go 1.22.4 from TUNA
bash "$SKILL_DIR/scripts/go/install.sh" -v 1.22.4

# List available Python versions
bash "$SKILL_DIR/scripts/python/install.sh" -v list

# Dry run
bash "$SKILL_DIR/scripts/go/install.sh" -d

All install scripts support: -v/--version, -m/--mirror, -d/--dry-run, -y/--yes

---

3b. CONFIGURE MIRROR — point package managers to Chinese sources

For users who have tools but want to speed up package downloads:

Tool	Script	Default Mirror
pip/uv/poetry	scripts/python/setup.sh	tuna
npm/yarn/pnpm	scripts/node/setup.sh	npmmirror
APT (Ubuntu/Debian)	sudo scripts/apt/setup.sh	tuna
Docker CE (install repo)	sudo scripts/docker/setup.sh	tuna
Docker Hub (image pull)	sudo scripts/docker/setup.sh	tuna
Homebrew	scripts/homebrew/setup.sh	tuna
Conda channels (.condarc)	scripts/conda/setup.sh	tuna
Cargo (crates.io)	scripts/rust/setup.sh	ustc
Go modules (GOPROXY)	scripts/go/setup.sh	goproxy
Flutter/Dart	scripts/flutter/setup.sh	cfug
GitHub Releases/Clone	scripts/github/setup.sh	tuna
Hugging Face downloads	scripts/huggingface/download.sh	hf-mirror

Examples:

bash "$SKILL_DIR/scripts/python/setup.sh" --mirror tuna
bash "$SKILL_DIR/scripts/node/setup.sh" --mirror npmmirror
sudo bash "$SKILL_DIR/scripts/apt/setup.sh" --mirror tuna
bash "$SKILL_DIR/scripts/rust/setup.sh" --mirror ustc
bash "$SKILL_DIR/scripts/go/setup.sh"

All setup scripts support: -m/--mirror, -f/--force, -d/--dry-run, -y/--yes

---

4. Diagnose (when user wants to troubleshoot or audit)

bash "$SKILL_DIR/scripts/diagnose.sh"

Tests connectivity, shows current mirror status, and generates prioritized recommendations.

---

5. Quick environment scan (before configuring)

# Detect installed tools
for tool in pip uv npm yarn pnpm docker cargo go conda flutter brew; do
  which $tool 2>/dev/null && echo "✓ $tool found" || echo "✗ $tool not found"
done

# Check proxy conflicts
[[ -n "$HTTP_PROXY$HTTPS_PROXY$http_proxy$https_proxy" ]] && echo "⚠️ Proxy detected"

If a tool is not found and the user wants to use it → suggest running the appropriate install.sh first, then setup.sh.

---

6. Proxy conflict warning

If HTTP_PROXY or HTTPS_PROXY is set:

Proxy environment variables are set. In China, using a VPN/proxy alongside mirrors can cause conflicts. Consider: unset http_proxy https_proxy HTTP_PROXY HTTPS_PROXY

---

7. Hugging Face downloads

bash "$SKILL_DIR/scripts/huggingface/download.sh" gpt2 --tool hfd
bash "$SKILL_DIR/scripts/huggingface/download.sh" wget2 --dataset --tool cli --local-dir ./wget2

Injects HF_ENDPOINT=https://hf-mirror.com only for that command.

---

8. Verify configurations

pip config get global.index-url 2>/dev/null
npm config get registry 2>/dev/null
go env GOPROXY 2>/dev/null
cat ~/.cargo/config.toml 2>/dev/null | grep index
cat ~/.condarc 2>/dev/null | head -5
rustup show active-toolchain 2>/dev/null
go version 2>/dev/null

---

9. Summary to user

Report:

• Tool installs: which tools were installed, their version, install path
• Mirror configs: tool → mirror URL mapping
• Warnings: proxy conflicts, permission issues, tool not found
• Restore: bash "$SKILL_DIR/scripts/restore_config.sh" --tool <name> --latest

---

Backup & Restore

bash "$SKILL_DIR/scripts/backup_config.sh" --all
bash "$SKILL_DIR/scripts/backup_config.sh" --tool pip
bash "$SKILL_DIR/scripts/restore_config.sh" --tool pip --latest
bash "$SKILL_DIR/scripts/restore_config.sh" --list

Dry Run

Add --dry-run to any script to preview changes:

bash "$SKILL_DIR/scripts/python/install.sh" --dry-run
bash "$SKILL_DIR/scripts/python/setup.sh" --dry-run
