在今天之前，它一直在工作。我不知道为什么它今天不能工作。

如果任何人仍然面临jsonDecoder错误的问题。尝试从pycharm文件夹的venv中删除yfin。不知何故，我的系统在pycharm的venv中没有升级yfin。我不得不手动删除yfin文件夹并升级yfin。它现在为我工作。谢谢https://stackoverflow.com/a/68601710/16442394

下面的补丁修复了我的问题:在/usr/local/lib/python3.8/dist-packages/yfinance/base.py中进行以下更改：
# Getting data from json
num_tries = 4
url = "{}/v8/finance/chart/{}".format(self._base_url, self.ticker)
while num_tries > 0:
data = self.session.get(
url=url,
params=params,
proxies=proxy,
headers=utils.user_agent_headers
)
if "Will be right back" in data.text:
raise RuntimeError("*** YAHOO! FINANCE IS CURRENTLY DOWN! ***\n"
"Our engineers are working quickly to resolve "
"the issue. Thank you for your patience.")
if data.status_code == 404:
_time.sleep(0.5)
num_tries -= 1
continue
else:
data = data.json()
break
if num_tries == 0:
print("%s failed to get information"%self.ticker)
