当我创建一个laravel项目时，作曲家的一切都很顺利。但是，当我尝试访问默认的index.php页面时，我收到500错误。检查日志后，我发现这是Laravels源代码中的语法错误。我发现变量前面是'......'。
[Wed Nov 02 01：47：45.658110 2016] [：error] [pid 4561] [客户 70.66.236.55:55751] PHP解析错误：语法错误，意外'。'，期待'＆amp;'或变量（T_VARIABLE）in /var/www/html/proj-dir/vendor/laravel/framework/src/Illuminate/Foundation/helpers.php 在第475行
修好后会弹出一个新的。这又重复了几次。不确定他们是否应该在那里，但我认为'... $ args'不是一个有效的语法（即使对于laravel）
在“修复”所有错误后，我会在浏览器中收到实际的错误消息！

我尝试过多次重建项目，但总是在同一个地方。不确定如何继续。
答案 0 :(得分：4)
仅供参考，这些都没有语法错误。很可能你正在使用旧版本的PHP。确保您的服务器符合以下要求：
PHP＆gt; = 5.6.4
OpenSSL PHP扩展
PDO PHP扩展
Mbstring PHP扩展
Tokenizer PHP扩展
XML PHP扩展
也不要忘记为存储，bootstraps等目录提供必要的权限。
安装Laravel后，您可能需要配置一些权限。 存储和 bootstrap / cache 目录中的目录 您的网络服务器应该可写，否则Laravel将无法运行。如果你 正在使用Homestead虚拟机，这些权限应该 已经确定了。
在这里，您可以快速找到启动和运行laravel项目所需的一切。
