【中文标题】Mac Xcode 没有安装 python 库【英文标题】：Mac Xcode not installing python libraries 【发布时间】：2020-10-31 08:27:24 【问题描述】：我试图通过 pip 在我的新 mac 机器上安装 python 库。但由于某些 xcode 错误，它无法安装。我已经安装了 Xcode 应用程序和 Xcode 命令行工具。
Mac os 版本：- Catalina 10.15.7 我已经安装了最新的 xcode 命令行工具。
这里我分享命令行的回溯。
主要错误如下：
fatal error: too many errors emitted, stopping now [-ferror-limit=]
20 errors generated.
error: command 'xcrun' failed with exit status 1
这里我分享命令行的回溯。
