error: Distribution `psycopg-binary==3.2.2 can‘t be installed for the current platform

在Mac OS上执行如下命令时，很意外地报错了 

git clone git@github.com:fastapi/full-stack-fastapi-template.git
cd full-stack-fastapi-template/backend
uv sync

 错误内容：

$ uv sync
Using CPython 3.12.5 interpreter at: /usr/local/opt/python@3.12/bin/python3.12

error: Distribution `psycopg-binary==3.2.2 @ registry+https://mirrors.cloud.tencent.com/pypi/simple/` can't be installed because it doesn't have a source distribution or wheel for the current platform

原因：

当前系统在镜像源里，没有psycopg-binary==3.2.2的安装包

(我电脑比较老，新版的psycopg不支持）

解决：

$ uv pip install "psycopg[binary]"
Resolved 3 packages in 3.26s
Prepared 1 package in 2.71s
Installed 3 packages in 5ms
 + psycopg==3.1.19
 + psycopg-binary==3.1.19
 + typing-extensions==4.12.2

可以看到支持mac11.7的psycopg最高是到3.1.19

于是只需把pyproject.toml中的版本依赖改成<3.1.20即可

-    "psycopg[binary]<4.0.0,>=3.1.13",
+    "psycopg[binary]<3.1.20,>=3.1.13",

然后，再重新执行uv sync即可
