メモ: PHP 学習：PEARのインストール

公開：2026.04.18 11:37

PEAR

PEAR と書いて "ペア"(梨) と呼ぶ。 PEAR = PHP Extension and Application Repository
PHPのライブラリやパッケージを管理するシステムのこと。

いまさらながらPEARを使おうと思っていたが、もう昔のものらしい。
今の主流はComposerとのこと。

図書館で「プロになるためのPHPプログラミング入門」という本を借りたが、出版は2012年2月。
HTML_Template_Flexyというのを使っていて(これも現在は非推薦)、そしてこれを使うにはPEARが必要、ということで先に進むためPEARとHTML_Template_Flexyを入れることにした。

こういう技術本はなるべく最新のものを読まないと苦労する。

PHP環境

過去記事：Docker 学習 #4：Docker Composeを学ぶで作成したPHPコンテナを使用する。
以下コマンドでコンテナを起動。

docker compose up -d

コンテナのbashに接続する。

docker exec -it (CONTAINER ID) /bin/bash

※ (CONTAINER ID)は "docker ps" コマンドで確認。

PEAR環境を作る

Geminiに聞いてみた。

[方法1] パッケージマネージャを使ってインストールする。

apt update
apt install php-pear

実行結果：インストールできなかった

3 packages can be upgraded. Run 'apt list --upgradable' to see them.
root@05fa4e42bbcd:/var/www/html# apt install php-pear
Package php-pear is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Error: Package 'php-pear' has no installation candidate

[方法2] go-pear.pharを使って直接インストールする。

wget http://pear.php.net/go-pear.phar

実行結果：

root@05fa4e42bbcd:/var/www/html# wget http://pear.php.net/go-pear.phar
bash: wget: command not found

wgetが無いらしいのでインストール：

root@05fa4e42bbcd:/var/www/html# apt install wget

もう一度 go-pear.phar のダウンロードをやってみる。
今度はOK!

続いてインストール実行

php go-pear.phar

実行結果：なにやら色々聞いてきた。[Enter]押せばいいとのこと。

Below is a suggested file layout for your new PEAR installation.  To
change individual locations, type the number in front of the
directory.  Type 'all' to change all of them or simply press Enter to
accept these locations.

 1. Installation base ($prefix)                   : /usr/local
 2. Temporary directory for processing            : /tmp/pear/install
 3. Temporary directory for downloads             : /tmp/pear/install
 4. Binaries directory                            : /usr/local/bin
 5. PHP code directory ($php_dir)                 : /usr/local/lib/php
 6. Documentation directory                       : /usr/local/docs
 7. Data directory                                : /usr/local/data
 8. User-modifiable configuration files directory : /usr/local/cfg
 9. Public Web Files directory                    : /usr/local/www
10. System manual pages directory                 : /usr/local/man
11. Tests directory                               : /usr/local/tests
12. Name of configuration file                    : /usr/local/etc/pear.conf

1-12, 'all' or Enter to continue:

PEAR: To install optional features use "pear install pear/PEAR#featurename"

The 'pear' command is now at your service at /usr/local/bin/pear

** The 'pear' command is not currently in your PATH, so you need to
** use '/usr/local/bin/pear' until you have added
** '/usr/local/bin' to your PATH environment variable.

Run it without parameters to see the available actions, try 'pear list'
to see what packages are installed, or 'pear help' for help.

Thanks for using go-pear!
