运行 rdagent collect_info 时报告 找不到 litellm>=1.73的错误

经过大模型查找并修正后可以正常运行了，将错误现象和修复信息发在这里，供参考：

故障说明

在已正确安装rdagent及其依赖包的conda环境中，执行 rdagent collect_info 命令时出现 PackageNotFoundError: No package metadata was found for litellm>=1.73 错误，导致命令执行失败。

环境信息

• 操作系统: Linux
• Python版本: 3.13.9
• rdagent版本: 0.8.0
• litellm版本: 1.80.7 (已正确安装且满足>=1.73要求)

原因定位

问题出现在 /rdagent/app/utils/info.py 文件的 rdagent_info() 函数中：

1. 错误代码位置: 第74行 version = importlib.metadata.version(package)
2. 根本原因: 代码直接使用requirements.txt中包含版本要求的包名（如 litellm>=1.73）作为参数传递给 importlib.metadata.version() 函数
3. 技术细节: importlib.metadata.version() 函数只接受纯包名（如 litellm），不能处理包含版本约束符号（>=, ==, < 等）的字符串

修复方案

在第70-75行之间添加包名解析逻辑：

python

修复前的问题代码

for package in package_list:
if package == "typer[all]":
package = "typer"
version = importlib.metadata.version(package) # 这里会失败
package_version_list.append(f"{package}=={version}")

修复后的代码

for package in package_list:
if package == "typer[all]":
package = "typer"
# 从版本要求中提取纯包名
import re
package_name = re.split(r'[<>=!]', package)[0].strip()
try:
version = importlib.metadata.version(package_name)
package_version_list.append(f"{package_name}=={version}")
except importlib.metadata.PackageNotFoundError:
logger.warning(f"Package {package_name} not found in current environment")
continue

修改备注

• 添加正则表达式解析，从版本约束字符串中提取纯包名
• 增加异常处理，避免因个别包缺失导致整个命令失败
• 保持向后兼容性，不影响现有功能

English Bug Report

Issue Description

When executing rdagent collect_info command in a conda environment with rdagent and its dependencies properly installed, the command fails with
PackageNotFoundError: No package metadata was found for litellm>=1.73 error.

Environment Information

• OS: Linux
• Python Version: 3.13.9
• rdagent Version: 0.8.0
• litellm Version: 1.80.7 (properly installed and meets >=1.73 requirement)

Root Cause Analysis

The issue occurs in the rdagent_info() function within /rdagent/app/utils/info.py:

1. Error Location: Line 74 version = importlib.metadata.version(package)
2. Root Cause: The code directly passes package names with version constraints (e.g., litellm>=1.73) from requirements.txt to the importlib.metadata.version() function
3. Technical Details: importlib.metadata.version() only accepts pure package names (e.g., litellm) and cannot handle strings containing version constraint operators (>=, ==, <, etc.)

Fix Implementation

Add package name parsing logic between lines 70-75:

python

Problematic code before fix

for package in package_list:
if package == "typer[all]":
package = "typer"
version = importlib.metadata.version(package) # This fails
package_version_list.append(f"{package}=={version}")

Fixed code

for package in package_list:
if package == "typer[all]":
package = "typer"
# Extract pure package name from version requirements
import re
package_name = re.split(r'[<>=!]', package)[0].strip()
try:
version = importlib.metadata.version(package_name)
package_version_list.append(f"{package_name}=={version}")
except importlib.metadata.PackageNotFoundError:
logger.warning(f"Package {package_name} not found in current environment")
continue

Modification Notes

• Added regex parsing to extract pure package names from version constraint strings
• Implemented exception handling to prevent command failure due to missing individual packages
• Maintains backward compatibility without affecting existing functionality
