无法在 PyCharm 中安装任何软件包

Question

我试图在 PyCharm 中安装 python 包。 但我看不到任何最新版本如下：

我使用 pip 安装了一些软件包，但它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：

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

然后它显示“找不到满足 auto-py-to-exe 要求的版本（来自版本：）没有为 auto-py-to-exe 找到匹配的发行版”

所以我试图给它一个版本命令：(base) C:>pip install auto-py-to-exe from versions 2.7.5 --trusted-host pypi.org --trusted-host files.pythonhosted.org 但是仍然在这里显示相同的问题：

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

然后我出去了......所以如果有人有任何想法，请帮忙。 非常感谢。
