エラー解決の方法をまとめる

エラー概要

下記コマンドを実行後エラーが出力された。
```
$ brew install php@7.4
```

エラー文を下記に記載する。

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
Error: The following formula
  [#<Dependency: "python" []>, #<Options: []>]
cannot be installed as binary package and must be built from source.
Install the Command Line Tools:
  xcode-select --install

エラー文の和訳を下記に記載する。

    xcrun：エラー：無効なアクティブな開発者パス（/ Library / Developer / CommandLineTools）、xcrunがありません：/ Library / Developer / CommandLineTools / usr / bin / xcrun
    エラー：次の式
      [＃<依存関係： "python" []>、＃<オプション：[]>]
    バイナリパッケージとしてインストールすることはできず、ソースからビルドする必要があります。
    コマンドラインツールをインストールします。
      xcode-select --install
    ```

原因

xcrunと言うものがないことが原因らしい。

解決方法

下記コマンドを実行して必要な物をインストールする。
```
$ xcode-select --install
```
下記のようなポップアップが表示されるので「インストール」をクリックする。
下記のウインドウが開いたら「同意する」をクリックする。
インストールが開始されるので少々待つ。
下記のウインドウが開いたらインストールが完了している。「完了」をクリックする。
今一度下記コマンドを実行する。(下記のエラーが出ればOK、すでにインストールされているという内容のエラーである。)
```
$ xcode-select --install
>xcode-select: error: command line tools are already installed, use "Software Update" to install updates
```
再度PHPをインストールするコマンドを実行する。
```
$ brew install php@7.4
```

`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python/libexec/bin

You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.7/site-packages

icu4c is keg-only, which means it was not symlinked into /usr/local,
because macOS provides libicucore.dylib (but nothing else).

If you need to have icu4c first in your PATH run:

  echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> ~/.bash_profile

For compilers to find icu4c you may need to set:
  export LDFLAGS="-L/usr/local/opt/icu4c/lib"
  export CPPFLAGS="-I/usr/local/opt/icu4c/include"

For pkg-config to find icu4c you may need to set:

To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php7_module /usr/local/opt/php/lib/httpd/modules/libphp7.so

    <FilesMatch \.php$>
        SetHandler application/x-httpd-php
    </FilesMatch>

Finally, check DirectoryIndex includes index.php
    DirectoryIndex index.php index.html

The php.ini and php-fpm.ini file can be found in:
    /usr/local/etc/php/7.4/

To have launchd start php now and restart at login:
  brew services start php
Or, if you don't want/need a background service you can just run:
  php-fpm

==> Caveats
==> apr
apr is keg-only, which means it was not symlinked into /usr/local,
because Apple's CLT package contains apr.

If you need to have apr first in your PATH run:
  echo 'export PATH="/usr/local/opt/apr/bin:$PATH"' >> ~/.bash_profile

==> apr-util
apr-util is keg-only, which means it was not symlinked into /usr/local,
because Apple's CLT package contains apr.

If you need to have apr-util first in your PATH run:
  echo 'export PATH="/usr/local/opt/apr-util/bin:$PATH"' >> ~/.bash_profile

==> libidn
Emacs Lisp files have been installed to:
  /usr/local/share/emacs/site-lisp/libidn
==> openldap
openldap 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.

If you need to have openldap first in your PATH run:
  echo 'export PATH="/usr/local/opt/openldap/bin:$PATH"' >> ~/.bash_profile
  echo 'export PATH="/usr/local/opt/openldap/sbin:$PATH"' >> ~/.bash_profile

For compilers to find openldap you may need to set:
  export LDFLAGS="-L/usr/local/opt/openldap/lib"

==> curl-openssl
curl-openssl is keg-only, which means it was not symlinked into /usr/local,

parallel can cause all kinds of trouble.

If you need to have curl-openssl first in your PATH run:

For compilers to find curl-openssl you may need to set:
  export LDFLAGS="-L/usr/local/opt/curl-openssl/lib"

For pkg-config to find curl-openssl you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/curl-openssl/lib/pkgconfig"

==> libtool
In order to prevent conflicts with Apple's own libtool we have prepended a "g"
so, you have instead: glibtool and glibtoolize.
==> libffi
libffi is keg-only, which means it was not symlinked into /usr/local,
because some formulae require a newer version of libffi.

For compilers to find libffi you may need to set:
  export LDFLAGS="-L/usr/local/opt/libffi/lib"

For pkg-config to find libffi you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"

==> readline
readline is keg-only, which means it was not symlinked into /usr/local,
because macOS provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.

For compilers to find readline you may need to set:
  export LDFLAGS="-L/usr/local/opt/readline/lib"
  export CPPFLAGS="-I/usr/local/opt/readline/include"

For pkg-config to find readline you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/readline/lib/pkgconfig"

==> sqlite
sqlite is keg-only, which means it was not symlinked into /usr/local,
because macOS provides an older sqlite3.

If you need to have sqlite first in your PATH run:
  echo 'export PATH="/usr/local/opt/sqlite/bin:$PATH"' >> ~/.bash_profile

For compilers to find sqlite you may need to set:
  export LDFLAGS="-L/usr/local/opt/sqlite/lib"
