playwright环境(centos)
装libstdc/升级gcc
参考：https://stackoverflow.com/questions/70155008/how-to-install-devtoolset-8-in-rhel-8-image
- 用轻量级包管理microdnf
sudo dnf install microdnf
使用microdnf装gcc-toolset
microdnf install -y gcc-toolset-12启用一个名为gcc-toolset-12的软件集合
scl enable gcc-toolset-12 bash装libstdc++
sudo yum install libstdc++.x86_64
升级make
bash
sudo dnf -y install make设置UTF-8
bash
yum -y install glibc-locale-source glibc-langpack-en
sudo localedef -c -f UTF-8 -i en_US en_US.UTF-8
export LC_ALL=en_US.UTF-8下载依赖

def playwright_test():
from playwright.sync_api import sync_playwright
with sync_playwright() as pw:
browser = pw.chromium.launch(headless=True``)
context = browser.new_context(viewport={"width": 1920, "height": 1080})
page = context.new_page()
page.goto("https://twitch.tv/directory/game/Art") # go to url
page.wait_for_selector("div[data-target=directory-first-item]") # wait for content to load
parsed = []
stream_boxes = page.locator("//div[contains(@class,'tw-tower')]/div[@data-target]")
for box in stream_boxes.element_handles():
parsed.append({
"title": box.query_selector("h3").inner_text(),
"url": box.query_selector(".tw-link").get_attribute("href"),
"username": box.query_selector(".tw-link").inner_text(),
"viewers": box.query_selector(".tw-media-card-stat").inner_text(),
# tags are not always present:
"tags": box.query_selector(".tw-tag").inner_text() if box.query_selector(".tw-tag") else None,
})
for video in parsed:
print(video)
if __name__ == "__main__":
playwright_test()正常返回则证明可以。
