pip 安装 jq 依赖项失败

Question

这是我关于stackoverflow的第一个问题。 我设法安装了其他需要的软件包，例如箭头，但我无法安装jq 。 https://pypi.org/project/jq/

我尝试使用以下命令在 Win10 上安装jq （有代理限制，python 3.7.7）：

(project) C:\project>pip --proxy=https://xxx:8080 install jq

Output：

我还将 pip 和 setuptools 升级到版本 47.3.0 谁能给我一个提示，我的问题有什么解决方案？ 非常感谢。

Answer 1

尝试升级您的 setuptools 和 pip 版本。

python -m pip --proxy=https://xxx:8080 install --upgrade pip setuptools jq

看看urllib.error.URLError: <urlopen error [Errno 11002] getaddrinfo failed>？

Answer 2

是不是您需要一个 https 代理？ 您可以通过在详细模式下运行命令来获取有关根本原因的更多信息。

pip -v --proxy=https://xxx:8080 install jq
