我收到了这条消息

connect() failed (111: Connection refused

这是我的日志：

我正在使用 nodejs/express Elastic Beanstalk 环境。

我有一个 nginx 相关文件

.ebextensions/nginx/conf.d/proxy.conf

上层文件包含：

client_max_body_size 50M;

每当我尝试获取我的网页时，我都会收到 502 错误的网关。

我的应用程序有什么问题？

我用mac和我安装了gatsby-cli:

npm install --global gatsby-cli

和'npm root -g'命令打印:

/usr/local/lib/node_modules/npm/lib/node_modules

npm成功安装了gatsby但是,我无法运行gatsby命令(gatsby --version,gatsby --help)每当我键入并运行"gatsby --version"时它会打印:

-bash: gatsby: command not found

有什么办法可以解决这个问题吗？
