[英]Trying to install php-mbstring on ubuntu 20.04
I'm just trying to create a new laravel project and faced with this message我只是想创建一个新的 laravel 项目并遇到此消息
Creating a "laravel/laravel" project at "./example-app"
Installing laravel/laravel (v8.5.22)
- Installing laravel/laravel (v8.5.22): Extracting archive
Created project in /home/alifirhas/0_Work/Belajar/postgresql/example-app
> @php -r "file_exists('.env') || copy('.env.example', '.env');"
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.
Problem 1
- laravel/framework[v8.40.0, ..., 8.x-dev] require ext-mbstring * -> it is missing from your system. Install or enable PHP's mbstring extension.
- Root composer.json requires laravel/framework ^8.40 -> satisfiable by laravel/framework[v8.40.0, ..., 8.x-dev].
To enable extensions, verify that they are enabled in your .ini files:
- /etc/php/8.0/cli/php.ini
- /etc/php/8.0/cli/conf.d/10-opcache.ini
- /etc/php/8.0/cli/conf.d/10-pdo.ini
- /etc/php/8.0/cli/conf.d/20-calendar.ini
- /etc/php/8.0/cli/conf.d/20-ctype.ini
- /etc/php/8.0/cli/conf.d/20-exif.ini
- /etc/php/8.0/cli/conf.d/20-ffi.ini
- /etc/php/8.0/cli/conf.d/20-fileinfo.ini
- /etc/php/8.0/cli/conf.d/20-ftp.ini
- /etc/php/8.0/cli/conf.d/20-gettext.ini
- /etc/php/8.0/cli/conf.d/20-iconv.ini
- /etc/php/8.0/cli/conf.d/20-phar.ini
- /etc/php/8.0/cli/conf.d/20-posix.ini
- /etc/php/8.0/cli/conf.d/20-readline.ini
- /etc/php/8.0/cli/conf.d/20-shmop.ini
- /etc/php/8.0/cli/conf.d/20-sockets.ini
- /etc/php/8.0/cli/conf.d/20-sysvmsg.ini
- /etc/php/8.0/cli/conf.d/20-sysvsem.ini
- /etc/php/8.0/cli/conf.d/20-sysvshm.ini
- /etc/php/8.0/cli/conf.d/20-tokenizer.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
Looks like I have to install php-mbstring on my computer, so I run the command看起来我必须在我的电脑上安装 php-mbstring,所以我运行命令
sudo apt-get install php-mbstring
as i found in this thread: laravel/framework requires ext-mbstring正如我在这个线程中发现的: laravel/framework requires ext-mbstring
But there is another error message但是还有另一个错误信息

So does anyone know how to install php-mbstring?那么有人知道如何安装 php-mbstring 吗? or how can i make a laravel project?或者我怎样才能制作一个 laravel 项目?
I hope you guys can help me with this problem, please.我希望你们能帮我解决这个问题,拜托。 I've been working on this problem for almost 8 hours and still can't find a solution.我已经在这个问题上工作了将近 8 个小时,但仍然找不到解决方案。
Turns out i have to enabled universe repository to my system, like this原来我必须为我的系统启用 Universe 存储库,就像这样
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"
sudo apt-get update #to update my system
As Jarad said in this thread Cannot install php-mbstring on ubuntu 18.04 .正如 Jarad 在此线程中所说, Cannot install php-mbstring on ubuntu 18.04 。 And then i can just run然后我就可以跑了
sudo apt-get install php-mbstring
But turns out, i have to be specific what version that i want to install.但事实证明,我必须具体说明我要安装的版本。 If i just run php-mbstring
, will just install mbstring for php 8.0 not version installed on system.如果我只是运行php-mbstring
,只会为 php 8.0 安装 mbstring,而不是系统上安装的版本。 I have to be specific, then i run command我必须具体,然后我运行命令
sudo apt-get install php7.4-mbstring
(I moved to php7.4) (我搬到了php7.4)
And it run perfectly.它运行完美。 Also thank you @Nico Haase and @Peter Krebs for helping.还要感谢@Nico Haase 和@Peter Krebs 的帮助。
What works for me is to specify the version, and don't forget to update:对我有用的是指定版本,并且不要忘记更新:
sudo apt update
sudo apt install php7.4-mbstring
Have you tried a system update?你试过系统更新吗?
sudo apt-get upgrade
I used this just today, hope it helps you as well.我今天才用这个,希望对你也有帮助。
I came to this issue today for php8.0-mbstring module, and I found that the correct repository i not available in my system so my method was this and it worked for me, hope it will hep you too:我今天为 php8.0-mbstring 模块遇到了这个问题,我发现我的系统中没有正确的存储库,所以我的方法是这样的,它对我有用,希望它也能帮助你:
