pyppeteer-install下载遇到SSL问题

问题

当你想安装pyppeteer下载chromium，但是遇到如下的问题：

urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='npm.taobao.org', port=443): Max retries exceeded with url: /mirrors/chromium-browser-snapshots/Linux_x64/575458/chrome-linux.zip (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)')))

是不是很崩溃？这里告诉你一个小小技巧，比网上大部分的答案，更可靠。

解决方案

• 编辑lib/python3.7/site-packages/pyppeteer/chromium_downloader.py 这个文件

因为我是python3.7版本，路径就是这个，其他版本请自行修改。

 77     with urllib3.PoolManager() as http:
 78         # Get data from url.
 79         # set preload_content=False means using stream later.
 80         data = http.request('GET', url, preload_content=False)

第77行改成

 77     with urllib3.PoolManager(cert_reqs='CERT_NONE') as http:
 78         # Get data from url.
 79         # set preload_content=False means using stream later.
 80         data = http.request('GET', url, preload_content=False)

• 再次执行安装

$ pyppeteer-install 
[W:pyppeteer.chromium_downloader] start chromium download.
Download may take a few minutes.

是不是很简单。
