如何在 Ubuntu 16.04 中安装 Laravel

有人在 Ubuntu 16.04 上安装了 laravel 5 吗?我刚刚切换到 Ubuntu 16.04,我正尝试使用 composer 在其上安装 laravel 5 框架。但每次我尝试创建项目时,都会出现此错误

Installation failed, deleting ./composer.json.

我读过文章其中之一Ubuntu 16.04 默认自带 PHP7,但我们仍然可以使用 PHP5。但是我尝试了 PHP7 和 PHP5,仍然出现相同的错误!有什么想法吗?谢谢

如何在 Ubuntu 16.04 中安装 Laravel

更新:Laravel 5.4

由于对这个问题非常感兴趣,我决定更新它并创建一个小型 bash 脚本来安装使用 Laravel 所需的一切(这个是使用 NGINX 的)

https://github.com/emilas44/laravel-5.4-on-Ubuntu/blob/master/script.sh

您可以简单地复制并根据需要编辑它...也许您已经安装了一些脚本内的组件,如果是这样,您可以自由删除不需要的部分。


Laravel 5.2 如下:

安装基本内容(可选)

sudo apt-get install git
sudo apt-get install zip

sudo apt-get install tasksel
sudo tasksel install lamp-server

卷曲

sudo apt-get install curl php-curl php-mcrypt php-mbstring php-gettext

启用模组

sudo phpenmod mcrypt
sudo phpenmod mbstring
sudo a2enmod rewrite
sudo systemctl restart apache2

作曲家

curl -sS https://getcomposer.org/installer | php
sudo mv composer.phar /usr/local/bin/composer

安装 phpmyadmin

sudo apt-get install phpmyadmin     

稍后可通过 localhost/phpmyadmin 访问

创建 Laravel 项目

cd /var/www/html/
sudo composer create-project laravel/laravel work --prefer-dist
sudo chmod -R 777 work (do not set 777 on "live" server!)

创建虚拟主机 work.com

sudo gedit /etc/apache2/sites-available/work.com.conf

并将其粘贴到该文档中


#/etc/apache2/sites-available/work.com.conf contains following lines
<VirtualHost *:80>
        ServerName work.com
        DocumentRoot /var/www/html/work/public

        <Directory /var/www/html/work/public>
            AllowOverride All
            Require all granted
        </Directory>
</VirtualHost>

启用该站点

sudo a2ensite work.com
service apache2 reload

修复 hosts 文件,以便您可以通过 Web 浏览器访问它

sudo gedit /etc/hosts //space between gedit and destination!

        #/etc/hosts contents following lines                                
        127.0.0.1       work.com

或者使用此命令

sudo -- sh -c "echo '\n127.0.0.1 \twork.com'>> /etc/hosts"

就这样 laravel 就安装完成了!

我在 youtube 上制作了一个教程,教你如何正确使用 laravel。这里是链接: https://www.youtube.com/watch?v=A6TdaRIsG6g

答案2

我已经将 php 5.6.11 升级到 5.6.21。

因此,就我而言,我必须运行:

sudo apt-get install php5.6-mbstring

PS:我如何从 5.6.11 升级到 5.6.21 如下:

sudo LC_ALL=C.UTF-8 add-apt-repository ppa:ondrej/php 
sudo apt-get update 
sudo apt-get install php5.6

升级原因:zend_mm_heap 已损坏在作曲家更新期间。

答案3

这些是我在全新升级后在 Ubuntu Server 16.04 上安装 Laravel 5 的步骤

首先我必须彻底删除所有 PHP,正如 Mohammad Barhoush 所说:

  • sudo apt-get -y purge php.*

然后我使用以下命令重新安装了 PHP:

  • sudo apt install php libapache2-mod-php
  • sudo apt install php-cli
  • sudo apt install php-mysql

重新安装 PHP ver.7.0 后,我安装了 Mohhammad 推荐的附加相关软件包:

  • sudo apt-get install curl php-curl php-mcrypt php-mbstring php-gettext php-gd

并启用了模组

  • sudo phpenmod mcrypt

  • sudo phpenmod mbstring

    最后,毕竟这个作曲家仍然很痛苦,抱怨它没有 zip 扩展名,所以composer update我安装了以下内容:

  • sudo apt-get install php7.0-zip

此后它运行良好,没有任何错误!

这些是我从之前的 Ubuntu Server LTS 版本运行 laravel 5 所需的步骤。希望这对您有所帮助!谨致问候 :)

答案4

oerdnj 的解决方案有效,安装后你应该在运行之前mbstring启用它。在我的例子中,laravel 需要 ext-mbstring 和 ext-dom:php.inicomposer install
apt-get install php-dom
