Windows7安裝nginx後，'nginx -t -c nginx.conf' 命令出現 「could not open error log file: CreateFile() "logs...

網上搜索安裝nginx的方法，按照步驟在 http://nginx.org/en/download.html 下載了安裝包，並配置了conf/nginx.conf，將nginx的根目錄添加進了環境變量path中；
打開命令行，進入 'D:\nginx-1.15.3\conf' 目錄，執行以下命令驗證配置文件的正確性：

nginx -t -c nginx.conf

結果提示錯誤：

nginx: the configuration file 'D:\nginx-1.15.3\conf/nginx.conf syntax is ok
nginx: [emerg] CreateDirectory() "'D:\nginx-1.15.3\conf/temp/client_body_temp" failed (3: The system cannot find the path specified)
nginx: configuration file 'D:\nginx-1.15.3\conf/nginx.conf test failed

而且運行以下命令：

nginx -t

也是出現錯誤提示：

nginx: [emerg] CreateFile() "'D:\nginx-1.15.3\conf/conf/nginx.conf" failed (3: The system cannot find the path specified)
nginx: configuration file 'D:\nginx-1.15.3\conf/conf/nginx.conf test failed

百思不得其解，後來在命令行上退出 conf 目錄，回到根目錄 'D:\nginx-1.15.3' ，以下運行命令：

D:\nginx-1.15.3> nginx -t -c conf\nginx.conf

則顯示配置文件正確：

nginx: the configuration file D:\nginx-1.15.3/conf\nginx.conf syntax is ok
nginx: configuration file D:\nginx-1.15.3/conf\nginx.conf test is successful

而且，運行命令：

D:\nginx-1.15.3> nginx -t

顯示nginx安裝正常

nginx: the configuration file D:\nginx-1.15.3/conf/nginx.conf syntax is ok
nginx: configuration file D:\nginx-1.15.3/conf/nginx.conf test is successful

附 nginx 經常使用命令：

驗證配置是否正確: nginx -t

查看Nginx的版本號：nginx -V

啓動Nginx：start nginx

快速中止或關閉Nginx：nginx -s stop

正常中止或關閉Nginx：nginx -s quit

配置文件修改重裝載命令：nginx -s reload
