electron-builder没有绑定python文件

这是我的目录结构,其中renderer.js包含在index.html中。python脚本visitor.pydownload.py是通过python-shellrenderer.js调用的。一旦我捆绑,它就无法找到python脚本

|_ index.html
  |_ styles.css
  |_ main.js
  |_ package.json
  |_ dist/
  |_ node_modules/
  |_ renderer.js
  |_ visitor.py
  |_ download.py

字符串
我试着把files: [...]中的所有东西都放在build > files下的package.json中,然后运行npm run dist。我还试着把python文件显式复制到dist文件夹中,然后运行npm run dist。没有一个工作。
test.app/Contents/Resources/app.asar/remderer.js:226错误:python:无法打开文件'visitor.py':[错误2]没有这样的文件或目录
这是我的package.json

Please makeure not your typo

/Application/test.app/Contents/Resources/app.asar/remderer.js:226 Error: python: can't open file 'visitor.py': [Error 2] No such file or directoryremderer.js,但其他地方是renderer.js,所以请确保不是您的错别字。如果是,请更正。

原因

实际上electron-builder捆绑你的python文件,但由于asar,你的python-shell无法找到你的python文件,所以导致错误。

如何修复

解决方案一:

最好但官方不推荐:禁用asar

如何使用disable asar

package.json更改为:

{
...
  "build": {
    "appId": "com.example.app",
...
    "asar": false,

字符串
然后在你的renderer.js,其中包含python-shell代码,可能像这样:

import {PythonShell} from 'python-shell';

PythonShell.run('visitor.py', null, function (err) {
  if (err) throw err;
  console.log('finished');
});


现在应该工作了。

内部逻辑

禁用asar后,所有相关的文件路径都不包含asar,变成这样:

  • /Application/test.app/Contents/Resources/app/visitor.py
  • /Application/test.app/Contents/Resources/app/renderer.js

也就是说,.app文件结构为:

|_ test.app
    |_ Contents
        |_ Resources
            |_ app
                |_ styles.css
                |_ main.js
                |_ package.json
                |_ dist/
                |_ node_modules/
                |_ renderer.js
                |_ visitor.py
                |_ download.py
                ...

方案二:

继续启用asar,将额外文件放入unpack

asar解压方法

package.json更改为:

{
...
  "build": {
    "appId": "com.example.app",
...
    "asar": true,
    "asarUnpack": [
      "visitor.py",
      "download.py"
      "renderer.js"
    ],


打包的.app文件结构是:

|_ test.app
    |_ Contents
        |_ Resources
            |_ app.asar             # a single compressed binary file
            |_ app.asar.unpacked    # a folder/directory, contain unpacked origin files
                |_ visitor.py
                |_ download.py
                |_ renderer.js


你的renderer.js也许不需要改变,应该工作。
有关asarUnpack的更多详细信息,请参阅官方文档:Overridable per Platform Options
PS:其他一些asar和相关的尝试,可以参考我的中文帖子:【已解决】mac中PyInstaller打包后的二进制文件在electron-builder打包后app中有些无法通过child_process的execFile运行

您需要按如下方式指定它们:

"extraFiles": [
        "from":"source path",
        "to":"your destination"
    ]

字符串
如果你想把这些文件通过创建目录然后使用extraResources

"extraResources": [
        "from":"source path",
        "to":"some directory name"
    ]
