安装3.5.6,3.6.7时,Mojave上的pyenv抛出未声明的标识符'CLOCK_REALTIME'和其他错误

Question

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

我试过,通过brew:

1. 重新安装所有的pyenv,python,python3,xz,readline,openssl(每此答案)
2. 我已经尝试安装并重新安装macOS开发人员工具
3. 我试过了sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /(根据pyenv文档)
4. 我尝试了一个新的Mojave运行版本10.14.1 (18B75),我遇到了同样的问题.

哦,而且,我正在使用Fish.我将不得不查看这是否是鱼类特定的问题(更新:不,它不是鱼,它发生在标准中/bin/sh)

Answer 1

如果您想要维护不同版本的 python，asdf是一个不错的选择。您可以使用以下步骤进行安装。

git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.6.2

由于您似乎使用鱼，您可以执行以下操作

echo 'source ~/.asdf/asdf.fish' >> ~/.config/fish/config.fish
mkdir -p ~/.config/fish/completions; and cp ~/.asdf/completions/asdf.fish ~/.config/fish/completions

此时，您需要重新启动终端以使 asdf 生效。您可能需要自制安装一台 mac 操作系统coreutils automake autoconf openssl libyaml readline libxslt libtool unixodbc，因为某些插件可能需要它们。

然后你现在就可以安装 python 插件了。首先需要拉它。

asdf plugin-add python

安装插件后，就可以安装所需的版本了。

asdf install python 3.5.6
asdf install python 3.6.7

成功安装后，您可以使用以下命令在它们之间切换

asdf global python <version-of-your-choice: eg. 3.5.6>

例如。asdf 全局 python 3.5.6

我希望这有帮助。
