【问题描述】:
我在使用 brew 时遇到了 openssl 和 python@2 问题,which have explained here (unresolved)。记录的重新安装 Python 和 openssl 的解决方法不起作用,所以我决定卸载并重新安装 Python。
问题是,当您尝试使用 brew 安装 Python 2 时,您会收到以下消息:
brew install python@2
Error: No available formula with the name "python@2"
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
git -C "$(brew --repo homebrew/core)" fetch --unshallow
python@2 was deleted from homebrew/core in commit 028f11f9e:
python@2: delete (https://github.com/Homebrew/homebrew-core/issues/49796)
EOL 1 January 2020.
We gave it 1 month more to live so that people had time to migrate.
All in all, developers had 11 years to do their migration.
You can use the `brew extract` command and maintain python@2 in your own
tap if necessary:
https://docs.brew.sh/How-to-Create-and-Maintain-a-Tap
To show the formula before removal run:
git -C "$(brew --repo homebrew/core)" show 028f11f9e^:Formula/python@2.rb
If you still use this formula consider creating your own tap:
https://docs.brew.sh/How-to-Create-and-Maintain-a-Tap
不幸的是,我仍然有许多依赖于 Brew 的 python@2 的 brew 公式。其中包括awscli、letsencrypt、公关sshuttle 例如
aws
zsh: /usr/local/bin/aws: bad interpreter: /usr/local/opt/python@2/bin/python2.7: no such file or directory
我不知道如何使用他们记录的这个brew extract 命令来重新安装 Python@2。它需要一个公式和一个水龙头。我想公式是python@2。我不确定水龙头需要是什么。
另外重新安装诸如aws或letsencrypt之类的水龙头也不能很好地工作。
重新安装awscli (brew reinstall awscli) 后,运行aws 命令仍然报错。
aws

if original_result is 0:
usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:
aws help
aws <command> help
aws <command> <subcommand> help
aws: error: the following arguments are required: command
