在 MacOS 10.15 上使用 Pip install 安装包

Question

使用 Python3.7.3、MacOS 10.15

无法安装包 - 羽毛 试过 pip3 安装羽毛

返回错误：

    ImportError

错误：命令出错，退出状态为 1：python setup.py egg_info 检查日志以获取完整的命令输出。

我要做的就是避免在 spyder 中出现这个错误

ModuleNotFoundError: 没有名为“羽毛”的模块

谁能帮我解释一下为什么我会遇到这样的问题

似乎缺少 setuptools。 试试pip3 install setuptools

这是报告错误的地方。

            # Setuptools 0.7b and later is a suitable (and preferable)
            # substitute for any Distribute version.
            try:
                pkg_resources.require("setuptools>=0.7b")
                return
            except (pkg_resources.DistributionNotFound,
                    pkg_resources.VersionConflict):
                pass

            if not hasattr(pkg_resources, '_distribute'):
                if not no_fake:
                    _fake_setuptools()
                raise ImportError

setuptools 的版本号是多少？
