在pycham或Spider IDE上安装scrapy时，为什么会出现错误？

Question

在pycham上安装Scrapy时出现以下日志错误。

Collecting Scrapy
Could not fetch URL https://pypi.org/simple/scrapy/: There was a problem confirming the SSL certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/scrapy/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping

pip配置了需要TLS / SSL的位置，但是Python中的SSL模块不可用。

  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/scrapy/

  Could not find a version that satisfies the requirement Scrapy (from versions: )

找不到Scrapy的匹配分布 pip配置了需要TLS / SSL的位置，但是Python中的SSL模块不可用。

我也尝试在Spider IDE上安装Scrapy，但出现以下错误

pip install scrappy
