When I run a html file using "snapshot render.html svg", what are the some errors ? How to resovle it?

@Rease123

• Are you running at Linux?
• If you are running at Linux, you should change the source code for await pyppeteer.launch(options={'args': ['--no-sandbox']})

Hi! I just hit this issue (on Linux) - when you say "change the source code" could you point me to where this is?

[vsoch]

I suspect here?

pyecharts-snapshot/pyecharts_snapshot/main.py

Lines 171 to 178 in ca916c0

	async def get_echarts(url: str, snapshot_js: str):
	browser = await launch()
	page = await browser.newPage()
	await page.goto(url)
	content = await page.evaluate(snapshot_js)
	await browser.close()
	return content

Would you accept a pull request to add a command line argument for --no-sandbox? I think there are likely a lot of Linux users (and this would be useful for them too!)

@vsoch Have you solved this problem on linux?

I didn't pursue it further because there was no response above, and wound up using plotly in Python with some html templates and it produced the chart I was looking for. https://github.com/vsoch/citelang/blob/5b0fe38553afd90b19bfe918ca7b5ea56d5b513d/citelang/main/badge/__init__.py#L9
