升级梨认为我是1.9.3，但梨说是1.9.0版本
我是一个非常新手，但希望能有所帮助。
我刚才刚刚成功安装了 PHPUnit。
我的环境是Wamp2.1。
我不知道这是如何工作的，但它对我有用，所以试试这个。
pear clear-cache 那么，
pear install -a -f phpunit/PHPUnit
在失败消息的某个地方，我看到了有关缓存的内容，所以我使用了clear-cache.
我猜它在安装过程中做了一些技巧。
祝你好运！
来自手册页
pear channel-discover pear.phpunit.de
pear channel-discover components.ez.no
pear channel-discover pear.symfony-project.com
pear install phpunit/PHPUnit
确保您具有所需的两个额外通道。
编辑：
请尝试遵循以下建议：pear update-channels

.tgz" Unable to create directory 'C:/Program/tmpFA83.tmp'
Unable to create path for C:/Program/tmpFA83.tmp/package.xml
这是梨安装程序中的一个错误。它无法处理路径中的空间并尝试读取错误的文件。将 php 安装在没有空格的文件夹中是我所知道的唯一"修复"：/
更新 5：
pear install --force --alldeps pear/pear
执行它要求的所有频道更新
pear install --force --alldeps phpunit/PHPUnit
如果系统要求频道更新，请执行这些操作并重复
如果Pear命令不起作用，请尝试以下操作：
首先，我假设 xampp 已安装到 C：''xampp
- 打开命令提示符并转到 C：''xampp''php
- 键入"梨更新通道"(更新通道定义(
- 键入"梨升级"(升级所有现有软件包和梨(
- 键入"梨通道发现 components.ez.no"(PHPUnit 需要这样做(
- 键入"梨通道-发现 pear.symfony-project.com"(PHPUnit 也需要(
- 键入"梨通道-发现 pear.phpunit.de"(这是 PHP unit(
- 键入"pear install --alldeps phpunit/PHPUnit"(安装 PHPUnit 和所有依赖项(
您安装了多个 PEAR 版本，但执行了错误的版本。看窗户上的梨显示不同的版本号，以了解如何修复它。
请确保您以管理员身份运行命令提示符并按照此操作进行操作
pear channel-discover pear.phpunit.de
pear channel-discover components.ez.no
