类型错误:流未定义 [英] TypeError: stream is undefined

问题描述

无法向我的小型反应应用程序添加数据库连接，我尝试了一堆 npm 模块:sqlite、sqlite3、realm.全部退回类型错误:

Can't add a database connection to my small react app, i tried a bunch of npm modules: sqlite, sqlite3, realm. All fall back with type error:

TypeError: stream is undefined

我什么都不做，只是在我的组件案例中添加了一个 require 语句，该错误:

i do absolutely nothing, just added a require statement in my component case that error:

import db from 'sqlite';

或:

var sqlite = require('sqlite3').verbose();

最后一个跟踪字符串:

(function (process){
module.exports = function (blocking) {
  [process.stdout, process.stderr].forEach(function (stream) {
    if (stream._handle && stream.isTTY && typeof stream._handle.setBlocking === 'function') {
      stream._handle.setBlocking(blocking)
    }
  })
}

实际构建失败，出现错误:找不到模块AccessibilityInfo"

and real fails on building, with Error: Cannot find module 'AccessibilityInfo'

推荐答案

您的最后一个跟踪指向 set-blocking npm 模块的内容.通常由 npmlog 使用.它需要 process.stderr 和 process.stdout 存在.在你的情况下，他们不是.如果您在 Electron 中运行该应用程序，则可能是这种情况.

Your last trace points to the content of set-blocking npm module. Usually it is used by npmlog. It requires process.stderr and process.stdout to be present. In your case they aren't. If you are running the app in Electron that might be the case.
