如果我使用pyinstaller，Pyppeteer将无法启动浏览器

问题描述

由于某些原因，如果您使用pyppeteer并尝试使用Pyinstaller进行构建，它将无法正常工作。

(node:13756) UnhandledPromiseRejectionWarning: TypeError: Assignment to constant variable.

(node:13756) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block,or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection,use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:13756) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future,promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

现在，使用Pyinstaller将其构建为EXE。

from pyppeteer import launch
import asyncio


async def browserLaunch():
    browser = await launch(headless=False,handleSIGINT=False,handleSIGTERM=False,handleSIGHUP=False,args=['--start-maximized'])
    page = (await browser.pages())[0]
    await page.goto("http://google.com")


asyncio.set_event_loop(asyncio.new_event_loop())
asyncio.get_event_loop().run_until_complete(browserLaunch())

启动可执行文件后，这将导致“无法执行脚本”错误。使其正常工作的唯一方法是在控制台或禁用--onefile的情况下进行构建。

pyinstaller --onefile -w browserTest.py

或

pyinstaller --onefile browserTest.py

但是，将“ -w”和“ --onefile”组合使用会导致脚本不起作用。我一直在互联网上搜寻无法找到答案的问题，还问reddit r / learnpython，他们也找不到解决方案。有什么想法吗？
