在 Mac M1 上安装 python 3.6.*

Question

我正在尝试运行需要 python < 3.7 的旧应用。我目前使用的是 python 3.9，需要使用 python.

的多个版本

我已经安装了 pyenv-virtualenv 和 pyenv 并成功安装了 python 3.7.13。但是，当我尝试安装 3.6.* 时，我得到了这个：

$ pyenv install 3.6.13
python-build: use openssl@1.1 from homebrew
python-build: use readline from homebrew
Downloading Python-3.6.13.tar.xz...
-> https://www.python.org/ftp/python/3.6.13/Python-3.6.13.tar.xz
Installing Python-3.6.13...
python-build: use tcl-tk from homebrew
python-build: use readline from homebrew
python-build: use zlib from xcode sdk

BUILD FAILED (OS X 12.3.1 using python-build 2.2.5-11-gf0f2cdd1)

有办法解决吗？我看过了，好像 Mac M1 不允许安装 3.6.*

我使用以下设置在 Apple M1 MacBook Pro 运行 Monterey 上成功安装了 Python 3.6。这里可能有些东西可以 removed/refined... 但它对我有用！

#Install Rosetta

# Install x86_64 brew
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

# Providing an incorrect openssl version forces a proper openssl version to be downloaded and linked during the build

注意，构建成功但给出以下警告

WARNING: The Python readline extension was not compiled. Missing the GNU readline lib?

运行 pyenv versions说明3.6.15可以被系统正常使用
