Composer global require Laravel/Installer not working on Ubuntu
提问by JonnySerra
I'm trying to run composer global require "laravel/installer"on my Ubuntu machine (Trenta OS Distro) and for some reason I can't get it to install.
我正在尝试composer global require "laravel/installer"在我的 Ubuntu 机器（Trenta OS Distro）上运行，但由于某种原因我无法安装它。
file_put_contents(./composer.json): failed to open stream: Permission denied
file_put_contents(./composer.json)：无法打开流：权限被拒绝
I get the error above on every attempt. I've been unable to find any help on google so I'm guessing this isn't a very common problem. I tried whereiscommand on that file and it gives me a location
每次尝试时我都会收到上述错误。我一直无法在谷歌上找到任何帮助，所以我猜这不是一个很常见的问题。我whereis在那个文件上试过 命令，它给了我一个位置
/usr/local/bin/composer
I tried running chmod -R 777on that file but it did nothing. I don't know what else to do.
我尝试chmod -R 777在该文件上运行但它什么也没做。我不知道还能做什么。
Composer was installed on my machine with the following command
使用以下命令在我的机器上安装了 Composer
curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
I thought composer.jsononly comes with projects, but I shouldn't need an existing project in order to simply set up the Laravel Installer right?
我以为composer.json只附带项目，但我不应该需要一个现有的项目来简单地设置 Laravel 安装程序，对吗？

I had the same problem and after reading this answerI solved it updating the .composerfolder permissions:
我遇到了同样的问题，在阅读此答案后，我解决了更新.composer文件夹权限的问题：
sudo chown -R $USER:$USER /home/$USER/.composer
Where $USERis your machine's username.
$USER你机器的用户名在哪里。
Update: As @Lucas Bustamante pointed, you don't need to change $USER for your username, its an environment variable already.
更新：正如@Lucas Bustamante 所指出的，您不需要为您的用户名更改 $USER，它已经是一个环境变量。
As Ian Warnercommented out, is not a good idea to run composer as sudo user, because it can lead to security issues.
正如Ian Warner评论的那样，以 sudo 用户身份运行 composer 不是一个好主意，因为它会导致安全问题。

I think this may solve your problem as it did for me.
我认为这可能会像对我一样解决您的问题。
I made a bash file for the whole process of global installation of Laravel. download it from here, open a terminal in the bash file directory and run the command below:
我为Laravel全局安装的整个过程制作了一个bash文件。 从这里下载它，在bash 文件目录中打开一个终端并运行以下命令：
bash Laravel_Global_Installer.sh
This bash file manages installations of:
这个 bash 文件管理安装：
- Latest version of PHP and its extensions
- Latest version of Composer (Global)
- Latest version of Laravel (Global)
- 最新版本的 PHP 及其扩展
- Composer 最新版本（全球）
- Laravel 最新版本（全球）
This will help you install Composer Globally and without sudo. Therefore you will be able to install Laravel Globally.
这将帮助您在没有 sudo 的情况下全局安装 Composer。因此，您将能够全局安装 Laravel。

usr/local/bin/composer composer global require "laravel/installer"
usr/local/bin/composer composer create-project --prefer-dist laravel/laravel myblog
回答by Nitin
use sudo before the command,
在命令前使用 sudo，
for e.g.: sudo composer global require "laravel/installer"
例如：sudo composer global 需要“laravel/installer”
