python - Mojave 上的 pyenv 在安装 3.5.6、3.6.7 时抛出未声明的标识符“CLOCK_REALTIME”和其他错误

问题描述

我正在尝试在 macOS Mojave 上安装各种版本的 python3 10.14.2 Beta (18C52a)。

3.6.7 失败：

我试过了，通过brew：

  1. 重新安装所有pyenv, python, python3, xz, readline, openssl（根据这个答案）
  2. 我已经尝试安装和重新安装 macOS 开发者工具
  3. 我试过sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /（根据 pyenv 文档）
  4. 我在一个新的 Mojave running 版本上尝试了这个10.14.1 (18B75)，我遇到了同样的问题。

哦，该死的，我正在使用 Fish。我将不得不看看这是否是鱼特定的问题（更新：不，它不是鱼，它发生在标准中/bin/sh）

解决方案

我不知道这是否是问题所在，但是当我尝试安装多个 pip 包时遇到了类似的错误，这些 pip 包的构建步骤依赖于time.h. 问题是我有一个流浪者，里面缺乏必要的出口/usr/local/include。如果您（错误）使用 brew，您可能会在/usr/local/*. 我建议获取详细的输出，找到产生错误的确切构建命令，查看每个-I标志，然后递归搜索time.h. 我敢打赌，其中一个是你想要摆脱的遗物。
