在带有M1芯片的Mac上安装python@2

Question

长话短说，我想在带有M1芯片组的MacBook Pro上安装Apache Cassandra。

为了安装它，必须先安装其他软件，其中一个是python，必须更新到最新版本。

当询问python现有版本时，终端显示如下:

> python --version 
Python 2.7.16

在教程中他们更新到2.7.17，所以我试着做同样的:

> brew install python@2

，这是输出:

Warning: No available formula or cask with the name "python@2". Did you mean bpython, ipython, jython or cython?
==> Searching for similarly named formulae...
These similarly named formulae were found:
bpython             ipython             jython              cython
To install one of them, run (for example):
brew install bpython
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.

有什么办法可以解决这个问题吗?

Answer 1

我可以在M1上安装2.7.18

brew install pyenv
pyenv install 2.7.18

设置python版本。

pyenv global 2.7.18

必要时导出PATH

export PATH="$(pyenv root)/shims:${PATH}"

必要时添加:

echo 'PATH=$(pyenv root)/shims:$PATH' >> ~/.zshrc

Answer 2

有时你会得到一些错误，比如缺少一些东西如果你正在使用Rosetta，那么运行:

arch -arm64 pyenv install 2.7.18

Answer 3

对于asdf版本管理器用户，可以安装python插件。

asdf plugin add python

然后你可以通过调用 来安装python2

asdf install python 2.7.18
# Then you can declare the local python
asdf local python 2.7.18
