# Python 3.9 部署说明
|
||||
|
||||
本文档面向 **Ubuntu 20.04** 等仅自带 **Python 3.8**、需单独安装 **3.9** 的服务器。
|
||||
项目代码兼容 **Python 3.9~3.12**;**推荐 3.10+**,3.9 为最低可用版本。
|
||||
|
||||
完整业务部署(PM2、config、备份)仍以 **[部署说明.md](部署说明.md)** 为主;本文只讲 **解释器版本与 venv**。
|
||||
|
||||
---
|
||||
|
||||
## 1. 版本要求
|
||||
|
||||
| Python | 能否部署 | 说明 |
|
||||
|--------|----------|------|
|
||||
| **3.8** | ❌ | `matplotlib==3.9.2` 不支持;类型注解 `str \| None` 会报错 |
|
||||
| **3.9** | ✅ | Ubuntu 20.04 常用;执行器需 `eval-type-backport`(已写入 `requirements.txt`) |
|
||||
| **3.10~3.12** | ✅ 推荐 | 与开发环境一致,无需额外兼容包 |
|
||||
|
||||
---
|
||||
|
||||
## 2. Ubuntu 20.04 安装 Python 3.9
|
||||
|
||||
系统默认 `python3` 指向 **3.8**,不要用它建 venv。
|
||||
|
||||
```bash
|
||||
sudo apt update
|
||||
sudo apt install -y python3.9 python3.9-venv python3.9-dev
|
||||
|
||||
python3.9 --version
|
||||
# 期望:Python 3.9.x
|
||||
```
|
||||
|
||||
> **说明**:Ubuntu 20.04 官方源通常有 `python3.9`,没有 `python3.10` 包时不必强求;用 3.9 即可。
|
||||
> 若需 3.10,可用 [deadsnakes PPA](https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa) 或 pyenv(见 [§8](#8-可选升级到-python-310))。
|
||||
|
||||
---
|
||||
|
||||
## 3. 扫描端 onchain_scout_gate
|
||||
|
||||
```bash
|
||||
cd /opt/gate_scout_order/onchain_scout_gate
|
||||
chmod +x deploy/*.sh
|
||||
|
||||
# 删除旧 venv(尤其曾用 3.8 或从 Windows 拷来的 .venv)
|
||||
rm -rf .venv
|
||||
|
||||
python3.9 -m venv .venv
|
||||
source .venv/bin/activate
|
||||
|
||||
python --version # 必须是 3.9.x,不能是 3.8
|
||||
pip install -U pip
|
||||
pip install -r requirements.txt
|
||||
pip install "socksio>=1.0,<2" || true # config 里 proxy.enabled=true 时需要
|
||||
|
||||
deactivate
|
||||
```
|
||||
|
||||
**配置与启动**(与主文档相同):
|
||||
|
||||
```bash
|
||||
[ -f config.yaml ] || cp config.example.yaml config.yaml
|
||||
chmod 600 config.yaml
|
||||
# 编辑 config.yaml 后:
|
||||
cd /opt/gate_scout_order/onchain_scout_gate
|
||||
pm2 start deploy/ecosystem.config.cjs
|
||||
pm2 save
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 4. 执行器 gate_order_executor
|
||||
|
||||
```bash
|
||||
cd /opt/gate_scout_order/gate_order_executor
|
||||
chmod +x deploy/*.sh
|
||||
rm -rf .venv
|
||||
|
||||
python3.9 -m venv .venv
|
||||
source .venv/bin/activate
|
||||
python --version
|
||||
pip install -U pip
|
||||
pip install -r requirements.txt
|
||||
pip install "socksio>=1.0,<2" || true
|
||||
deactivate
|
||||
|
||||
[ -f config.yaml ] || cp config.example.yaml config.yaml
|
||||
chmod 600 config.yaml
|
||||
|
||||
cd /opt/gate_scout_order/gate_order_executor
|
||||
bash deploy/pm2-start.sh
|
||||
pm2 save
|
||||
```
|
||||
|
||||
`requirements.txt` 已包含 **`eval-type-backport`**,供 Pydantic 在 3.9 下解析 `float | None` 等注解。
|
||||
若仍报 `Unable to evaluate type annotation`,请确认已执行 `pip install -r requirements.txt` 且 venv 为 3.9。
|
||||
|
||||
---
|
||||
|
||||
## 5. 一键自检
|
||||
|
||||
```bash
|
||||
# 扫描端
|
||||
/opt/gate_scout_order/onchain_scout_gate/.venv/bin/python --version
|
||||
/opt/gate_scout_order/onchain_scout_gate/.venv/bin/python -c "
|
||||
from app.proxy_util import httpx_proxy_url
|
||||
from app.config import load_settings
|
||||
print('scout import ok')
|
||||
"
|
||||
|
||||
# 执行器
|
||||
/opt/gate_scout_order/gate_order_executor/.venv/bin/python --version
|
||||
/opt/gate_scout_order/gate_order_executor/.venv/bin/python -c "
|
||||
from app.models_signal import TradeSignal
|
||||
print('executor import ok')
|
||||
"
|
||||
|
||||
pm2 status
|
||||
curl -s -o /dev/null -w "%{http_code}\n" http://127.0.0.1:8088/api/status
|
||||
curl -s http://127.0.0.1:8090/health
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 6. 常见报错(3.9 环境)
|
||||
|
||||
| 报错 | 原因 | 处理 |
|
||||
|------|------|------|
|
||||
| `No matching distribution found for matplotlib==3.9.2` | 用了 **Python 3.8** 的 venv | `rm -rf .venv` 后用 **`python3.9 -m venv`** 重建 |
|
||||
| `TypeError: unsupported operand type(s) for \|: 'type' and 'NoneType'`(`proxy_util.py`) | 3.9 下未延迟求值联合类型 | 确保 `app/proxy_util.py` 含 `from __future__ import annotations`(当前仓库已包含) |
|
||||
| `Unable to evaluate type annotation 'float \| None'` | 执行器 Pydantic + 3.9 | `pip install eval-type-backport` 或重装 `requirements.txt` |
|
||||
| PM2 日志里路径是 `/usr/lib/python3.8/` | PM2 未用项目 `.venv` | 在子项目目录 `pm2 delete` 后重新 `pm2 start deploy/...` |
|
||||
| 从本机 Windows 整包上传后无法启动 | `.venv` 不能跨系统复用 | **只打包代码 + config + runtime**;到 Linux 上按本文重建 venv |
|
||||
|
||||
---
|
||||
|
||||
## 7. 与「整目录打包迁移」配合
|
||||
|
||||
可以 tar 整个 `/opt/gate_scout_order`(含 `config.yaml`、`runtime/`),上传到新机后:
|
||||
|
||||
1. **删除** 两个子目录下的 `.venv`
|
||||
2. 按 [§3](#3-扫描端-onchain_scout_gate)、[§4](#4-执行器-gate_order_executor) 用 **python3.9** 重建 venv
|
||||
3. `pm2 restart` 或重新 `pm2 start`
|
||||
|
||||
数据与配置无需单独恢复;**环境必须在新机重装一遍**。
|
||||
|
||||
---
|
||||
|
||||
## 8. 可选:升级到 Python 3.10+
|
||||
|
||||
若希望与开发机完全一致、少踩 3.9 注解兼容问题:
|
||||
|
||||
```bash
|
||||
# Ubuntu 20.04 + deadsnakes(若 apt 有 python3.10)
|
||||
sudo add-apt-repository -y ppa:deadsnakes/ppa
|
||||
sudo apt update
|
||||
sudo apt install -y python3.10 python3.10-venv python3.10-dev
|
||||
|
||||
cd /opt/gate_scout_order/onchain_scout_gate
|
||||
rm -rf .venv && python3.10 -m venv .venv
|
||||
source .venv/bin/activate && pip install -U pip && pip install -r requirements.txt
|
||||
```
|
||||
|
||||
执行器同样用 `python3.10 -m venv`。
|
||||
**3.10+ 不强制需要 `eval-type-backport`**,保留在 requirements 里也无害。
|
||||
|
||||
---
|
||||
|
||||
## 9. 使用 bootstrap 脚本(自动选 3.10 / 3.9)
|
||||
|
||||
子目录 `deploy/bootstrap.sh` 会优先 `python3.12` → `3.11` → `3.10` → `3.9`,均不满足则报错退出:
|
||||
|
||||
```bash
|
||||
cd /opt/gate_scout_order/onchain_scout_gate
|
||||
bash deploy/bootstrap.sh /opt/gate_scout_order/onchain_scout_gate
|
||||
|
||||
cd /opt/gate_scout_order/gate_order_executor
|
||||
bash deploy/bootstrap.sh /opt/gate_scout_order/gate_order_executor
|
||||
```
