MacOS 通过 Brew 升级完 Python 打开终端出现一堆错误。

打开终端就出现如下错误，求帮助：

[TimePPT]

卸了重装吧
另外，建议用 pyenv 直接管理 Python 版本吧，想咋折腾咋折腾

[wangyzj]

哈哈
你犯了大忌了

[misaka19000]

降低 openssl 的版本

[Hanggi]

放弃 py 吧，真的是一坨浆糊，不想用。

[oahebky]

重装警告
重装警告
重装警告

[Ccbeango]

用 py 版本管理工具多好啊。

[abelzyp]

@wangyzj 对于你这种在一旁冷笑，站着说话不腰疼的这类人。我只能对你说：大佬，我是真不知道这是啥报错啊？救救孩子吧😭

[wangyzj]

环境变量改成 /Library/Frameworks/Python.framework/Versions 下面的试试

[U7Q5tLAex2FI0o0g]

https://github.com/Homebrew/legacy-homebrew/issues/22816

[jiejiss]

brew install openssl
brew link openssl --force
brew uninstall python
brew install python --with-brewed-openssl

[abelzyp]

我刚才照着这个帖子 https://www.jianshu.com/p/98383a7688a5 删除了 Python3.7 和 2.7，还是不行。求指教啊？
我现在 ls /Library/Frameworks/Python.framework/Versions 只有一个 Current，剩下啥都没了。

[WoodenRobot]

[]( https://zhuanlan.zhihu.com/p/117457048) 试试这个，我之前遇到过

[abelzyp]

@jiejiss 在执行 brew uninstall python 的时候，错误如下：
Error: Refusing to uninstall /usr/local/Cellar/python/2.7.13
because it is required by macvim and vim, which are currently installed.
You can override this and force removal with:
brew uninstall --ignore-dependencies python

我是应该按照提示进行么？

[Cuo]

可以换用 pyenv 管理 python 版本，将 pyenv 下的 python 路径设为全局变量后就可以无视 brew 安装的 python 了。

[wangyzj]

@abelzyp 有 timemachine 吗？

[U7Q5tLAex2FI0o0g]

我想问一下你一开始有 brew update 么

[Cuo]

@abelzyp 你在删除的是系统自带的 python，如果按照提示强制删除的话，之后可能出现依赖问题

[abelzyp]

@littleylv 执行 brew install python --with-brewed-openssl 的时候报错：Error: invalid option: --with-brewed-openssl，这块是命令不对么？我着实不太了解这块。

[abelzyp]

@Cuo 那可否装回来啊？我看通过 10 楼的最后一条命令，应该是装回来的意思吧？

[abelzyp]

@littleylv 有的，这块有什么联系么？

[gitopen]

pyenv 最好用！

[ivyliner]

conda 真香

[wzwwzw]

Python 别升级啊，直接重装啊。

[jiejiss]

@abelzyp #19 是的。按照提示来

[justin2018]

不要删除系统自带的

可以 brew install python3

安装好了后 python3 就是 3.xx 版本 python 是 2.xx 版本

[abelzyp]

@misaka19000
@WoodenRobot
两位大佬，我想问下，我这个错误与 OpenSSL 的关系是啥呢？我这边对这个问题不是很了解，刚接触。

[Livid]

[misaka19000]

@abelzyp #25 因为我前几天遇到了和你一模一样的问题，后来在网上查找资料，最后就是通过给 openssl 降级解决的，从 1.1.1 降级到 1.0.2

[abelzyp]

现在看来，下面四条命令是最好用的：
brew install openssl
brew link openssl --force
brew uninstall python
brew install python --with-brewed-openssl
但是我最后一条命令执行不成功，原因在上面我说了。
现在执行完成前三条命令后，我现在的报错信息已经是下面这个了，有人遇到过吗🤦‍♂️

/usr/local/lib/python2.7/site-packages/powerline/bindings/bash/powerline.sh:99: /usr/local/bin/powerline-config: bad interpreter: /usr/local/opt/python/bin/python2.7: no such file or directory
/usr/local/lib/python2.7/site-packages/powerline/bindings/bash/powerline.sh:102: /usr/local/bin/powerline-config: bad interpreter: /usr/local/opt/python/bin/python2.7: no such file or directory

[xingheng]

用 brew 安装 python 的你就是作死，死的透透的你就顿悟了。

[wangyzj]

@abelzyp 复制一份过去吧
最好的办法是恢复
你的系统自带的已经不见了
不知道为啥
或者给你打个包你放到那个路径试试

[Mark24]

brew 安装会编译，这是编译 Python 的时候，依赖有点问题。

卸掉，先装上编译 Python 需要的依赖，再安装 Python
