无法在PyCharm中安装任何软件包

Question

我试图在PyCharm中安装python软件包。但是我看不到任何最新版本，如下所示：

我用pip安装了一些软件包，但无法正常工作并显示：

(base) C:\>pip install auto-py-to-exe
Collecting auto-py-to-exe
  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)'))': /simple/auto-py-to-exe/
  Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)'))': /simple/auto-py-to-exe/
  Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)'))': /simple/auto-py-to-exe/
  Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)'))': /simple/auto-py-to-exe/
  Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)'))': /simple/auto-py-to-exe/
  Could not fetch URL https://pypi.org/simple/auto-py-to-exe/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/auto-py-to-exe/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)'))) - skipping

然后我尝试使用受信任的主机cmd：

（基本）C：> pip安装auto-py-to-exe --trusted-host pypi.org --trusted-host files.pythonhosted.org

然后显示“找不到满足auto-py-to-exe要求的版本（来自版本：） 找不到与py-to-exe匹配的分布”

所以我试图给它一个版本命令： （基本）C：> pip从2.7.5版本开始自动安装py-to-exe---trusted-host pypi.org --trusted-host files.pythonhosted.org 但是在这里仍然显示相同的问题：

Collecting auto-py-to-exe
  Could not find a version that satisfies the requirement auto-py-to-exe (from versions: )
No matching distribution found for auto-py-to-exe

那我出去了...所以，如果有人有什么想法，请帮忙。非常感谢。
