自制软件 python@2 和 python 提供损坏的 sqlite3
homebrew python@2 and python provides broken sqlite3
我正在使用最新版本的 macOS 和 homebrew，brew doctor 没有发现任何问题。我只是使用 brew install python, brew install python@2 来获取最新版本的 python.
当我键入 python -c "import sqlite3" 时，我收到以下错误消息：
python2.7 -c "import sqlite3"

可能导致问题的原因是什么？我尝试下载 python 源代码并编译它，并将 _sqlite3.so 或 _sqlite3.cpython-37m-darwin.so 文件移动到 brew 安装文件夹中，一切正常。 brew 会忘记配方中的某些东西吗？除了从源码编译.so文件，手动解决问题还能怎么办？
我终于找到了漏洞所在。
我所有的 macOS 设备（包括 2 个 Pros 和 1 个 Air）都共享同一个 .zshrc 文件，出于某种原因，我添加了一个
export DYLD_LIBRARY_PATH="/Users/myname/Library/Developer/Xcode/iOS DeviceSupport/10.0.1 (14A403)/Symbols/usr/lib/:/usr/lib/"
这破坏了 python sqlite 共享库文件的构建，最近为 sqlite 添加了一个名为“_sqlite3_enable_load_extension”的功能。
当我将 DYLD_LIBRARY_PATH 删除到过时的目录，然后 brew 重新安装 python 一切正常。
顺便说一下，brew config 和 brew doctor 没有提供关于 DYLD_LIBRARY_PATH 的信息。下次我会遵守规则并提供这些信息。
问题已解决！
