无法使用npm安装zerorpc

Question

我需要安装zerorpc。正如文档中提到的，我首先安装了zeromq，然后尝试了这个命令：npm install -g zerorpc，但我得到了这个错误:-

C:\WINDOWS\system32>npm install -g zerorpc

> zeromq@4.6.0 install C:\Users\Admin\AppData\Roaming\npm\node_modules\zerorpc\node_modules\zeromq
> node scripts/prebuild-install.js || (node scripts/preinstall.js && node-gyp rebuild)


prebuild-install WARN install No prebuilt binaries found (target=10.15.1 runtime=node arch=x64 platform=win32)

如何解决，请帮帮忙！

Answer 1

不要使用'zerorpc‘，而要使用'zeromq’来与nodejs和python通信。

请使用'https://zeromq.org/languages/python/‘安装Python，使用'https://zeromq.org/languages/java/’安装nodejs

python : pip install pyzmq

nodejs : npm install zeromq@5

- python代码

import zmq

context = zmq.Context()
socket = context.socket(zmq.REQ)
socket.connect("tcp://127.0.0.1:5502")

for counter in range(0, 100001):
    socket.send(b"Hello")
    message = socket.recv()

    if counter % 1000 == 0:
        print(message, counter)

- nodejs代码

var zeromq = require("zeromq");

var socket = zeromq.createSocket('rep');

socket.bind("tcp://127.0.0.1:5502",
            function(err)
            {
                if (err) throw err;
                console.log("Bound to port 5502.");

                socket.on('message', function(envelope, blank, data)
                          {
                              console.log(envelope.toString('utf8'));
                              socket.send(envelope.toString('utf8') + " Blancmange!");
                          });

                socket.on('error', function(err) {
                    console.log("Error: "+err);
                });
            }
);

操作系统: Mac

最终解决方案:将node版本从v13.5.0降级到v8.17.0

Answer 3

从您的日志中看，zeromq似乎没有成功安装，我建议您再次运行

npm install --save zeromq

在成功安装之后，您可以继续运行您的npm install --save zerorpc。

编辑:我建议你在这里使用你的package.json，完全删除node_modules目录，然后打开你的package.json并替换

"dependencies": {
  "zerorpc": "git+https://github.com/0rpc/zerorpc-node.git"
},

使用

  "dependencies": {
    "zeromq": "^5.1.0",
    "zerorpc": "^0.9.8"
  },

然后运行npm install

让我知道进展如何。
