Here are the last 10 lines from the log:

-----------------------------------------

No package 'krb5-gssapi' found
No package 'krb5' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables KERBEROS_CFLAGS
and KERBEROS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

インストールできない。。

いまいち原因が分からず調べていると以下のページを見つけた。

https://scrapbox.io/takoba/PHP7.4.2%E3%82%92macOS_Catalina%E3%81%ABphpenv%E3%81%A7%E3%82%A4%E3%83%B3%E3%82%B9%E3%83%88%E3%83%BC%E3%83%AB%E3%81%99%E3%82%8B

7.4.2だけどまあ大体同じでしょってことでこのコマンドで実行。

```
$ PHP_BUILD_CONFIGURE_OPTS="--with-zlib-dir=$(brew --prefix zlib) --with-bz2=$(brew --prefix bzip2) --with-iconv=$(brew --prefix libiconv) --with-libedit --with-tidy=$(brew --prefix tidy-html5) --with-openssl" PKG_CONFIG_PATH="$(brew --prefix krb5)/lib/pkgconfig:$(brew --prefix openssl)/lib/pkgconfig:$(brew --prefix icu4c)/lib/pkgconfig:$(brew --prefix libedit)/lib/pkgconfig:$(brew --prefix libxml2)/lib/pkgconfig" phpenv install 7.4.5
```

待つこと20分
