为什么此错误仅在构建docker镜像时发生

Question

我已经将我的Laravel应用程序从6更新到7，然后是8，没有问题。但是，当我尝试构建我的docker映像时，composer install --no-dev -o命令失败。如果我在我的终端上运行相同的命令，就不会出现错误。错误是

In Request.php line 335:
                                                                               
  Argument 1 passed to Symfony\Component\HttpFoundation\Request::create() mus  
  t be of the type string, null given, called in /app/vendor/laravel/framewor  
  k/src/Illuminate/Foundation/Bootstrap/SetRequestForConsole.php on line 32

用来构建镜像的命令是@docker build $(DOCKER_BUILD_ARG) -t $(IMAGE_TAG) -f $(DOCKERFILE) .，它看起来像是laravel框架文件的问题。我谷歌了这个错误，但没有找到任何解决方案。我尝试运行composer dump autoload，php artisan cache:clar和php artisan config:clear，这些都没有解决我的问题。

我的dockerfile看起来像这样：

FROM armcanada/php7-mssql:latest

# Copy files
ADD . /app/
ADD php.ini /etc/php.ini
ADD arm-http.conf /etc/httpd/conf.modules.d/arm-http.conf

# Install app dependencies
RUN composer install --no-dev -o

# Fix permissions
RUN chmod -R 777 ./storage
RUN chmod -R 777 ./bootstrap/cache

# Cache route & views
RUN php artisan route:cache
RUN php artisan view:cache

CMD ["start_httpd"]

和我的composer.json：

Answer 1

我设法通过编辑app/config.php文件解决了这个问题。错误是url键为空，因此我在env()函数中添加了一个默认值：

'url' => env('APP_URL', 'default'),

Answer 2

在运行composer安装之前，当我将.env文件放入其中时，我得到了相同的错误，然后它工作正常
