安装Laravel时出现Composer错误:'mbstring'丢失了？

Question

我决定尝试使用Laravel,因为与OOP PHP相比它是多么乏味,所以我一直在进行安装.

尽管如此,我正在尝试在我的cmd(.~/wamp/www /)上执行'composer create-project laravel/laravel --prefer-dist'命令,它创建了Laravel文件夹但是给了我这个输出:

*Installing laravel/laravel (v5.1.4)
  - Installing laravel/laravel (v5.1.4)
    Loading from cache

我正在使用Windows.

我尝试过安装一个新的作曲家,我试过复制一个laravel目录并手动将它放在我的/ www中.

我确保WAMP根据我读到的内容使用所有模块和扩展.

我编辑了php.ini文件,并在必要时采用了分号.

现在经过一些Google搜索,我迷失了.

有人可以帮我解决这个问题,我很感激.

提前致谢!

Answer 1

我有同样的问题.这是解决方案.

1. 转到php.ini文件.
2. 找到扩展名"extension = php_mbstring.dll".(ctrl + f可能不起作用,只需在php.ini中找到包含扩展名的长列表)
3. 取消注释扩展,您可以通过删除同一行中的分号来完成此操作.
4. 保存您的php.ini文件.

这可能不会是你最后一次遇到这样的事情.根据经验,请仔细阅读错误并对php.ini文件进行适当的更改.

祝好运!

安装php-mbstring使用,

sudo apt-get install php-mbstring

应该解决这个问题
