刪除站點包中的 .pth 文件后證書驗證失敗

Question

因此，當我使用以下命令行從 bitbucket 下載包（ site-packages ）時： pip install --upgrade git+ssh://git@bitbucket.ggf.com:7999/pyt/jira ， pip 開始不工作。

我嘗試調試並在此輸出中找到問題：

Traceback (most recent call last):
  File "C:\Programs\Python\lib\importlib\_common.py", line 89, in _tempfile
    os.write(fd, reader())

    with self.open('rb') as strm:
  File "C:\Programs\Python\lib\importlib\_adapters.py", line 54, in open
    raise ValueError()
ValueError

During handling of the above exception, another exception occurred:

我發現如果我從site-packages中刪除這兩個文件然后 pip 再次工作，所以由於某種原因這些文件使它卡住了，但我不知道為什么？

python-certifi-win32-init.pth
distutils-precedence.pth

現在這樣做的問題是安裝jira的包是一個需要通過 SSL 連接的 API，我猜通過刪除這些.pth文件現在會產生一些錯誤？

我得到這個輸出運行一個簡單的命令，它試圖連接到 Jira：

Traceback (most recent call last):

    return ssl_context.wrap_socket(sock, server_hostname=server_hostname)

    return self.sslsocket_class._create(

    self.do_handshake()

    self._sslobj.do_handshake()
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:997)

關於我應該刪除這些文件的方式有什么想法嗎？

Answer 1

通過刪除python-certifi-win32-init.pth庫的功能實際上會丟失。

python-certifi-win32的作者 Andrew Leech 建議繼續他的另一個項目pip-system-certs 。 用pip-system-certs ( PyPI link ) 替換庫為我解決了所有問題。
