已安装setuptools，使用--use-pep517安装pygwalker仍失败求助

执行安装命令：

pip install pygwalker --use-pep517  --proxy=<proxy>:<port>

执行pip show setuptools结果：

Name: setuptools

Home-page: https://github.com/pypa/setuptools

必须指定--use-pep517参数，否则会出现要求使用该参数的错误，请求协助解决安装失败问题。

解决方法 #

1. 复用本地已安装的setuptools #

添加--no-build-isolation参数，让pip直接使用当前环境已有的依赖，无需重新下载build依赖：

pip install pygwalker --use-pep517 --no-build-isolation --proxy=<proxy>:<port>

2. 验证代理配置有效性 #

从错误日志看，连接pypi.org超时，需确认：

• 代理地址、端口是否正确，能正常访问外网
• 若代理需用户名密码，格式应为--proxy=http://<username>:<password>@<proxy>:<port>
• 可先测试代理连通性：

curl -x <proxy>:<port> https://pypi.org/simple/setuptools/

3. 手动预安装duckdb的wheel包 #

失败根源是安装duckdb时编译依赖下载超时，可先手动下载对应Python版本和系统的duckdb wheel包，本地安装后再装pygwalker：

# 示例：假设下载的wheel包为duckdb-0.8.1-cp312-cp312-win_amd64.whl
pip install duckdb-0.8.1-cp312-cp312-win_amd64.whl
pip install pygwalker --use-pep517 --proxy=<proxy>:<port>

4. 延长pip超时时间 #

若因网络不稳定导致超时，可增加超时参数：

pip install pygwalker --use-pep517 --proxy=<proxy>:<port> --default-timeout=60
