Generating symlink...

Done. Phalcon Developer Tools installed!

Thank you for using Phalcon Developer Tools!

We hope that Phalcon Developer Tools helps to make your life easier.

To start using Phalcon Developer Tools you need to run ‘source /root/.bash_profile‘

/web/phalcon-devtools-3.2.12/phalcon.sh: line 150: php: command not found

[root@localhost phalcon-devtools-3.2.12]# php -v

bash: php: command not found

当报上面的错时，是没有添加路径。

所以，php -v 会报错。

通过phpinfo()查看到：php目录在：/usr/local/php/etc/php.ini

cd /usr/local/php

里面的bin目录。

将 /usr/local/php/bin目录添加到PATH中

修改：

cd ~

我这里的 ~ 即是 /root目录。你要注意用自己的。

vim .bash_profile

添加一句。

export PATH=$PATH:/usr/local/php/bin

保存之后。

source /root/.bash_profile

[root@localhost ~]# source /root/.bash_profile

[root@localhost ~]# php -v
