Question

当我尝试在Ubuntu 16.04 LTS的终端内安装：alphaunlimitedg@AUNs-PC:~/chatapplication$ npm install时。

这是我的聊天应用程序，我正在努力：

    {
    "name":"chat",
    "version":"0.0.1",
    "private":"true",
    "dependencies":
    {
        "socket.io":"1.4.8",
        "express":"4.14.0",
    }
}

我收到此错误：

alphaunlimitedg@AUNs-PC:~$ npm info express version

我已经尝试过多次尝试，因为您可以看到执行npm install命令行。

但由于某种原因，这并没有起作用，我猜测它是不是我的操作系统在Ubuntu中不支持或.json必须是一个真正的JSON文件的版本错误/问题在代码中还没有完成？而不只是JavaScript，因为错误描述了自己。

有人可以帮我解决这个问题吗？

您的文件无效，请删除依赖项中的最后一个逗号：

{
    "name":"chat",
    "version":"0.0.1",
    "private":"true",
    "dependencies":
    {
        "socket.io":"1.4.8",
        "express":"4.14.0"
    }
}

下次使用JSON验证器，例如this，您就会发现文件中存在错误：

Error: Parse error on line 7:
...ss": "4.14.0",       }    }
----------------------^
Expecting 'STRING', got '}'

另外，查看输出，如果创建一个带空格的目录，则需要将其转义才能访问它，所以：

cd chat application/

应该是

cd chat\ application/

当尝试安装NPM时，得到一个＆＃34; npm ERR！＆＃34;
