在分叉过程中需要sqlite3本机模块时，电子崩溃 [英] Electron crashes when requiring sqlite3 native module in forked process

问题描述

我试图在带有电子的子进程中使用sqlite3模块，但是出现未定义符号的错误.而且，仅当我从电子的node.js运行程序时才会发生错误，但是当我从通常的node.js运行程序时，一切正常.我认为问题可能与sqlite3模块的本地性"有关，我尝试了 electron-rebuild ， npm --build-from-source ，它们没有帮助

I'm trying to use sqlite3 module in a child process with electron, but I get error of undefined symbol. Also, the error happens only when I run the program from electron's node.js, but when I run the program from usual node.js everything works fine. I think the problem may be related to 'nativeness' of sqlite3 module, and I tried electron-rebuild, npm --build-from-source, they didn't help.

main.js:

const { fork } = require('child_process');
fork('fork');

fork.js:

const sqlite3 = require('sqlite3');

package.json:

package.json:

{
  "name": "bugreproduce_sqlite",
  "version": "1.0.0",
  "description": "",
  "main": "main.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "sqlite3": "^4.0.2"
  },
  "devDependencies": {
    "electron": "^3.0.5"
  }
}

输出:

> ./node_modules/electron/dist/electron .
/home/myuser/Programming/javascript/bugreproduce_sqlite/node_modules/electron/dist/electron: symbol lookup error: /home/myuser/Programming/javascript/bugreproduce_sqlite/node_modules/sqlite3/lib/binding/node-v64-linux-x64/node_sqlite3.node: undefined symbol: _ZN2v816FunctionTemplate3NewEPNS_7IsolateEPFvRKNS_20FunctionCallbackInfoINS_5ValueEEEENS_5LocalIS4_EENSA_INS_9SignatureEEEiNS_19ConstructorBehaviorENS_14SideEffectTypeE

推荐答案

我找到了根本问题.这是相关的问题和

I found the root problem. Here is the relevant issue and pull request 1, pull request 2 on GitHub.

我要临时解决此问题的步骤是:

My steps to temporarily fixing the problem were:

• 克隆节点-gyp git仓库
• checkout 到sqlite3想要的版本(目前为0.10.3)
• 从第二个请求请求中应用补丁
• 从主项目文件夹中通过 npm install ../path/to/patched/node-pre-gyp 安装此修补的Node-pre-gyp
• npm i-从源构建sqlite3 (不确定是否需要此命令)和主项目中的 ./node_modules/.bin/electron-rebuild 文件夹(我安装了电子重建)

• 调用设置了电子版本的 fork ，如下所示:

• Clone node-pre-gyp git repository
• checkout to the version sqlite3 wants(0.10.3 at the moment)
• Apply patch from the second pull request
• Install this patched node-pre-gyp via npm install ../path/to/patched/node-pre-gyp from the main project folder
• npm i --build-from-source sqlite3(not sure this command is needed) and ./node_modules/.bin/electron-rebuild from the main project folder (I installed electron-rebuild)

• call fork with electron version set, like this:

fork('fork'，[]，{信封:{ELECTRON_VERSION:"3.0.5"}});

这是一个hack，但它似乎可以正常工作.希望这个问题能在上游得到解决.

This is a hack, but it seems to work. Hope the problem will be fixed in upstream.

已固定了拉取请求链接(我使用了第二个拉取请求，而不是第一个)

edited: fixed pull request link (I used the second pull request, not the first)
