从脚本启动 Mongo 的 NPM 问题

Question

我正在尝试在 Debian 9 中运行一个名为 Streetmix 的项目。我已尽我所能遵循安装说明。因此，当我在 streetmix 文件夹中使用 NPM Start 命令（带或不带 sudo）时，我得到：

> streetmix@1.3.0 prestart /home/dpowell/streetmix/streetmix
> npm run mongo:start


> streetmix@1.3.0 mongo:start /home/dpowell/streetmix/streetmix
> mongod --fork --logpath /dev/null

about to fork child process, waiting until server is ready for connections.
forked process: 2076

Streetmix 的说明说我需要将 mongodb/bin 文件夹添加到 $PATH，但是命令 mongo --version 可以在任何文件夹中使用，我认为这意味着因为 mongo 在 usr/ bin 文件夹，它已经在我的 $PATH 中，对吗？ （我还启动了 mongod，然后启动了 Mongo shell 以确保它正常工作。我还创建了 /data/db 文件夹。

有人知道我的问题可能是什么吗？

以下是错误末尾提到的日志内容：

问题出在 --fork 上。我遇到了同样的问题。

您需要做的是从 package.json 中删除 prestart 和 mongo:start 脚本，在单独的终端中打开 mongodb。然后就可以正常运行 npm start 了！

附：确保你没有提交这个修改过的文件
