PEAR安装

看到PEAR章节，提到安装PEAR需要go-pear.bat，我机器上的PHP(v7.0.8)目录下，并没有go-pear.bat这个文件，网上查了一遍，怎么说的都有，最后还是在官网上找到解决方案。

Windows

After you have downloaded and installed PHP, you have to manually execute the batch file located in e.g. c:\php\go-pear.bat. Alternatively, download https://pear.php.net/go-pear.phar with your browser and save the output to a local file named go-pear.phar. You can then run

php go-pear.phar

in a Windows Command Prompt to start the installation.

The setup will ask you some questions and afterwards the PEAR Package Manager will be installed in the path, which you have specified during installation.

Finally you have to add that installation path to your PATH environment. Either do this manually (Start > Control Panel > System > Environment) or run (double-click) the newly generated PEAR_ENV.reg that's now found in the PHP source directory.

After that you can access the PEAR Package Manager by running the command pear in a Windows Command Prompt.

After changing php.ini, you will need to restart your web server.

Now check that PEAR works.

为什么目录下有可能不存在go-pear.bat？这是个问题。

大概是以下几个原因：

1.历史原因，曾经发布的包里是包含go-pear.bat的，现在新版本的已经取消【如此重要的扩展库，是不是天然包含更好一些？】

有待研究，慢慢补充

Instead use http://pear.php.net/go-pear.phar for a more stable and current

version of go-pear, more suited to your PHP version.

 

Thank you for your coopertion and sorry for the inconvenience!【这里有个错误单词，谁知道如何提交给PHP官方？】

ERROR: failed to mkdir C:\php\pear\data\Auth\Auth\Frontend

 

最后告诉我failed to mkdir C:\php\pear\data\Auth\Auth\Frontend，然而，我的PHP装在了D盘，这该如何是好？！？有没有提供一种指定路径的方式？或者，在哪里能改？

既然说failed to mkdir，有可能是因为权限，我是从“运行”中启动的cmd，找到快捷方式后，以管理员权限运行，这次报install ok:channel://pear.php.net/Auth-1.6.4，看来是安装成功。然后，按照刚才报错的理解，应该是装到C:\php\pear\里了，经查，确实在。那么，把C盘的pear目录复制到我的D盘PHP的pear目录。

这种方式，非常不智能。

 

http://pear.php.net/packages.php

这里是可安装的包

 

安装go-pear之后，会在php.ini中增加一行：

;***** Added by go-pear
include_path=".;D:\PHPx64\pear"
;*****

所以，使用require_once时，直接使用require_once("Numbers/Roman.php");即可。
