安置tesserocr库时呈现以下问题：（如图）

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

常用解决步伐： py -3 -m pip --trusted-host pypi.python.org install + 库名
