Mac上pyenv的安装及使用

安装

brew update

brew install pyenv

报错

复制代码

  git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
  git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow

那就执行这2句

还报错

复制代码

git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow

remote: Counting objects: 100% (365455/365455), done.

需要换源

参考 https://blog.csdn.net/u013549582/article/details/120887331

复制代码

## 更新 homebrew-cask（如果提示 No such file or directory 可以先跳过前三个命令）
cd "$(brew --repo)"/Library/Taps/homebrew/homebrew-cask
# 更换源
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git 
# 更新
git fetch --unshallow 
 
## 更新 homebrew-core
cd "$(brew --repo)"/Library/Taps/homebrew/homebrew-core
# 更换源
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
# 更新
git fetch --unshallow

再次执行

brew update

报错

复制代码

==> `brew cleanup` has not been run in 30 days, running now...

需要授权

复制代码

sudo chown -R $(whoami):admin /usr/local/* && sudo chmod -R g+rwx /usr/local/*

当然这里尽量缩小授权的范围

然后执行

brew install pyenv

终于执行完了

可能需要多执行几次

然后查看版本

pyenv versions

查看可以安装的版本

pyenv install -l

安装

pyenv install 3.8.8

然后报错

复制代码

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LC_ALL = (unset),
        LANG = "en_CN.utf-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
python-build: use openssl@1.1 from homebrew
python-build: use readline from homebrew

需要执行

复制代码

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

然后重新执行pyenv install 3.8.8

还是报错，见鬼了

复制代码

python-build: use openssl@1.1 from homebrew
python-build: use readline from homebrew

最后还是放弃了

https://www.python.org/downloads/macos/ 下载一个版本，手动安装，哭死

换了版本之后，

python3 -V

pip3 --version
