无法在macOS Catalina 10.15.4上安装bsddb3 Python包

Question

我已经使用Homebrew安装了berkeley-db，现在正在努力安装bsddb3 Python包。任何帮助都将不胜感激。

bash-3.2$ BERKELEYDB_DIR=/usr/local/Cellar/berkeley-db/18.1.32_1 pip install bsddb3

Answer 1

对我来说，诀窍是使用Homebrew安装berkeley-db@4，而不是berkeley-db。

brew install berkeley-db@4
BERKELEYDB_DIR=$(brew --prefix berkeley-db@4) pip install bsddb3

Answer 2

请勿将此问题报告给Homebrew/brew或Homebrew/core！

错误:您正在使用macOS 11.1。我们不提供对此预发布版本的支持。你会遇到一些公式的构建失败。请创建拉取请求，而不是在Homebrew的GitHub、Discourse、Twitter或IRC上请求帮助。您有责任解决在运行此预发布版本时遇到的任何问题。
