我收到此错误“无法解压缩数据；在MacOS 10.15上安装AWS EB CLI时，zlib不可用”

Question

我正在尝试安装AWS Elastic Beanstalk CLI（https://github.com/aws/aws-elastic-beanstalk-cli-setup），但在理解为什么它不起作用时遇到了最大的麻烦（我对这类东西不满意，所以可能很容易。）

我已遵循所有设置说明，但是运行此命令./aws-elastic-beanstalk-cli-setup/scripts/bundled_installer时得到以下输出和错误：

我的.zshrc文件中包含以下内容：

CFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix readline)/include -I$(xcrun --show-sdk-path)/usr/include"
LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix readline)/lib -L$(brew --prefix zlib)/lib"
CPPFLAGS="-I$(brew --prefix openssl)/include -I$(brew --prefix zlib)/include"

所以我不知道发生了什么...

唯一可以解释这一点的是在通过brew安装zlib时得到的以下消息：

==> Caveats
zlib is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

但是然后转到/usr/local/opt时，可以将zlib视为符号链接，所以我不明白。。

$ ll /usr/local/opt/

您可以尝试安装EB CLI via Homebrew。在我的情况下，这有效，而其他详细方法here没有。
