若在下载https://github.com/dbeaver/dbeaver/releases/download/25.2.5/dbeaver-ce-25.2.5-win32.win32.x86_64.zip文件时遇到问题,可能是网络因素或代理设置等原因。 像下载https://github.com/electron-userland/electron-builder-binaries/releases/download/appimage-12.0.1/appimage-12.0.1.7z文件时,会因网络因素导致无法下载 [^1]。还有设置代理后失败,出现 “fatal: unable to access 'https://github.com/lucidrains/bottleneck-transformer-pytorch.git/': Failed to connect to 127.0.0.1 port 7890: Connection refused” 这类报错 [^2]。在使用Git进行代码管理,执行git clone或git pull等操作时,也会因网络连接问题或代理设置不正确,出现 “fatal: unable to access ‘https://github.com/…/.git’: Recv failure Connection was reset” 的报错 [^3]。 若遇到下载问题,可尝试以下操作: 1. 检查网络连接,确保网络稳定且能正常访问GitHub。 2. 检查代理设置,若设置了代理,可尝试关闭代理或者重新配置正确的代理信息。 3. 尝试更换下载工具或浏览器进行下载。 ```python # 若使用Python的requests下载文件示例 import requests url = 'https://github.com/dbeaver/dbeaver/releases/download/25.2.5/dbeaver-ce-25.2.5-win32.win32.x86_64.zip' response = requests.get(url) if response.status_code == 200: with open('dbeaver-ce-25.2.5-win32.win32.x86_64.zip', 'wb') as file: file.write(response.content) print('文件下载成功!') else: print(f'下载失败,状态码:{response.status_code}') ```
