  • 一些可能有用的log
  • readline
  • sqlite
  • 其它

安装方式

homebrew

命令行

brew install python3 && cp /usr/local/bin/python3 /usr/local/bin/python

依赖

gdbm, readline, sqlite, xz

一些可能有用的log

readline

readline is keg-only, which means it was not symlinked into /usr/local,
because macOS provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.

For compilers to find readline you may need to set:
  export LDFLAGS="-L/usr/local/opt/readline/lib"
  export CPPFLAGS="-I/usr/local/opt/readline/include"

sqlite

  sqlite is keg-only, which means it was not symlinked into /usr/local,
because macOS provides an older sqlite3.

If you need to have sqlite first in your PATH run:
  echo 'export PATH="/usr/local/opt/sqlite/bin:$PATH"' >> ~/.bash_profile

For compilers to find sqlite you may need to set:
  export LDFLAGS="-L/usr/local/opt/sqlite/lib"
  export CPPFLAGS="-I/usr/local/opt/sqlite/include"

其它

命令行会先更新 homebrew，如果嫌慢可以先 ctrl+c 跳过
