python - 无法使用npm在Windows 10上安装zerorpc

Question

首先，我检查了How to install zeroRPC (python) on windows，但是找不到我的问题的答案。

我正在尝试使用以下方法安装zerorpc以将Electronjs与python结合使用:

npm install zerorpc --save

这是错误:

npm ERR! path git
npm ERR! code ENOENT
npm ERR! errno ENOENT
npm ERR! syscall spawn git
npm ERR! enoent Error while executing:

另外，这是我的package.json:

{
  "name": "pretty-calculator",
  "main": "main.js",
  "scripts": {
    "start": "electron ."
  },
  "dependencies": {
    "zerorpc": "git+https://github.com/fyears/zerorpc-node.git"
  },
  "devDependencies": {
    "electron": "^5.0.7",
    "electron-rebuild": "^1.8.5"
  }
}

我一直在关注本教程:

我的系统:

操作系统:Windows10。

Visual Studio 2017的

Python 3.7和2.7

Node LTS的最新版本

Electron的最新版本

编辑:我已经安装了Windows-build-tools。

npm install -g zerorpc

C:\Users\TXJ0890\OneDrive - Shire PLC\Desktop\python\Electronjs>npm install -g zerorpc

Answer 1

这是因为您安装了python3而不是python2(您应该这样做)，但是zeromq需要python2。

在您的计算机上安装Python2并修改PATH变量，以便它在python3之前找到python2。之后，您应该能够运行安装命令。记住以后要更改它!

如果这个答案来不及，我很抱歉。
