Laravel 中的 `php artisan migrate` 出错

Question

从 Laravel 4 开始，我一直使用 Laravel 项目，直到 7。但这是我第一次在新下载的 Laravel 中迁移数据库时遇到错误。这是我迁移时的错误：

        $e = $event->getThrowable();

        if (!$event->hasResponse()) {
            $this->finishRequest($request, $type);

            throw $e;
        }

        $response = $event->getResponse();

        // the developer asked for a specific status code
        if (!$event->isAllowingCustomResponseCode() && !$response->isClientError() && !$response->isServerError() && !$response->isRedirect()) {
            // ensure that we actually have an error response
            if ($e instanceof HttpExceptionInterface) {
                // keep the HTTP status code and headers
                $response->setStatusCode($e->getStatusCode());
                $response->headers->add($e->getHeaders());
            } else {
                $response->setStatusCode(500);
            }
        }

        try {
            return $this->filterResponse($response, $request, $type);
        } catch (\Exception $e) {
            return $response;
        }
    }

    /**
     * Returns a human-readable string for the specified variable.
     */
    private function varToString($var): string
    {
        if (\is_object($var)) {
            return sprintf('an object of type %s', \get_class($var));
        }

        if (\is_array($var)) {
            $a = [];
            foreach ($var as $k => $v) {
                $a[] = sprintf('%s => ...', $k);
            }

            return sprintf('an array ([%s])', mb_substr(implode(', ', $a), 0, 255));
        }

        if (\is_resource($var)) {
            return sprintf('a resource (%s)', get_resource_type($var));
        }

        if (null === $var) {
            return 'null';
        }

        if (false === $var) {
            return 'a boolean value (false)';
        }

        if (true === $var) {
            return 'a boolean value (true)';
        }

        if (\is_string($var)) {
            return sprintf('a string ("%s%s")', mb_substr($var, 0, 255), mb_strlen($var) > 255 ? '...' : '');
        }

        if (is_numeric($var)) {
            return sprintf('a number (%s)', (string) $var);
        }

        return (string) $var;
    }
}

错误

在此之前，我从 IIS 管理器启动 IIS。我不知道这是否会影响。我打开它是因为我运行我端有一个 C# web 应用程序。

看来这是作曲家的问题。只需尝试运行这个 bash 脚本：

composer dump-autoload
