在Ubuntu 16.04上安装laravel 5

有人在Ubuntu 16.04上安装了laravel 5吗？ 我刚刚切换到Ubuntu 16.04，我正在尝试使用composer在其上安装laravel 5框架。 但每次我尝试创建一个项目时，它都会给我这个错误

我读过文章其中一个人说Ubuntu 16.04默认配备PHP7，但我们仍然可以使用PHP5。 但是我尝试了PHP7和PHP5并仍然得到相同的错误！ 有任何想法吗？ 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的bash脚本来安装Laravel所需的一切（这个是与NGINX一起使用的）

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

您可以随意复制并编辑它…也许您已经安装了一些在脚本中的组件，如果是这样，您可以自由删除您不需要的部分。

Laravel 5.2低于：

基本东西安装（可选） 

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

灯 

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

curl 

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

启用mods 

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

composer php 

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

安装phpmyadmin 

 sudo apt-get install phpmyadmin

以后可以通过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  ServerName work.com DocumentRoot /var/www/html/work/public  AllowOverride All Require all granted

启用该网站 

 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

或使用此命令 

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

这就是laravel安装！

我已经在youtube上制作了一个如何使其正确的教程….所有你需要使用laravel的东西。 这是链接： https ： //www.youtube.com/watch？v = A6TdaRIsG6g

我已经将PHP 5.6.11升级到5.6.21。

所以，在我的情况下，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以下： 

 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：在composer php更新期间zend_mm_heap损坏 。

这些是我在新升级后在Ubuntu Server 16.04上安装Laravel 5时必须采取的步骤

首先，我必须完全删除所有PHP，因为Mohammad Barhoush说：

  • sudo apt-get -y purge php.*

然后我重新安装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推荐的其他相关软件包：

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

并启用了mod

  • sudo phpenmod mcrypt

  • sudo phpenmod mbstring

    最后，在所有这位composer php仍抱怨之后，它还没有用于composer update的zip扩展，所以我安装了以下内容：

  • sudo apt-get install php7.0-zip

之后它运行得很好，没有错误！

这些是我从前一个LTS版本的Ubuntu Server获得laravel 5function所需的步骤。 希望这有帮助！ 最好的祝福 ：）

PHP mbstring扩展现在位于一个单独的包中，因此您需要执行以下操作： 

 apt-get install php-mbstring

oerdnj的解决方案有效，在安装mbstring你应该在运行composer install之前在php.ini启用它。 在我的情况下，laravel需要ext-mbstring和ext-dom：
apt-get install php-dom

所以我遇到了与上面那个我需要安装php-dom的人一样的问题，所以我试着运行apt-get install php-dom但是它只是想出了消息 

 Package php-dom is a virtual package provided by: php5.5-xml 5.5.35-1+donate.sury.org~xenial+2 php7.0-xml 7.0.6-1+donate.sury.org~xenial+1 php5.6-xml 5.6.21-1+donate.sury.org~xenial+2 You should explicitly select one to install.

由于我有点新的终端我发现这有点令人困惑，但我运行unbuntu 16.04与php7所以我只是运行： apt-get install php7.0-xml ，这对我apt-get install php7.0-xml …希望有助于某人！

谢谢大家的回复..我终于能够通过以下方式解决这个问题：

  • 首先完全删除php：

    sudo apt-get -y purge php.*

  • 重新安装php和这些重要的相关包：

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

  • 启用mods（感谢lewis4uvideo）：

    sudo phpenmod mcrypt

    sudo phpenmod mbstring

你需要在配置文件中手动执行某些操作..我发现这篇文章真的很有帮助。 首先，需要检查天气mbstring.dll库已经在系统中使用’phpinfo（）’函数安装。 如果启用了，而不是取消注释’extension = php_mbstring.dll’，只需将其注释在php.ini配置文件中，或者如果它不存在，请通过sudo apt-get install php-mbstring php7.0-mbstring

然后只需配置以下内容。 

 ; mbstring.language = All ;mbstring.internal_encoding = UTF-8 ;mbstring.http_output = UTF-8 ;mbstring.encoding_translation = On ;mbstring.func_overload = 0

就是这样..我想你知道其他的事情，比如如何安装laravel和所有..

要在Urantu Ubuntu 16.04上安装Laravel 5.4 ，就像在Laravel文档中使用check一样：

  1. 在终端上检查你的PHP版本： php -v ，你的php版本必须是PHP >= 5.6.4
  2. 使用php -m检查终端，以获取OpenSSL PHP Extension和PDO PHP Extension 。

  3. 终端： sudo apt install php-mbstring并再次通过php -m检查Mbstring PHP Extension和Tokenizer PHP Extension 。

  4. 终端： sudo apt install php-xml并再次通过php -m检查XML PHP Extension

  5. 通过终端中的以下4个步骤下载Composer：

    • php -r“copy（’ https://getcomposer.org/installer'，'composer-setup.php ‘）;”

    • php -r“if（hash_file（’SHA384’，’composer-setup.php’）===’669656bab3166a7aff8a7506b8cb2d1c292f042046c5a994c43155c0be6190fa0355160742ab2e1c88d40d5be660b410’）{echo’Installer verified’;} else {echo’Installer corrupt’; unlink（’composer-setup。 php’）;} echo PHP_EOL;“

    • php composer-setup.php

    • php -r“unlink（’composer-setup.php’）;”

  6. 检查终端中的php composer.phar ： php composer.phar

  7. 在终端安装Laravel：

    php composer.phar global require "laravel/installer"
    终端中的输出将显示当前目录到/home/yourname/.config/composer ，转到当前目录并按ctrl+h显示隐藏文件。
    转到.config文件夹然后转到composer文件夹，其中包含以下内容： composer文件夹内容

  8. 在终端的/var/www/html中创建Laravel project ：

    php composer.phar create-project --prefer-dist laravel/laravel /var/www/html/myLaravel

  9. 在终端打开myLaravel然后粘贴： php artisan serve并在浏览器中复制http://127.0.0.1:8000
