python - 如何解释这个回溯？

Question

我正在设置一台新的开发机器并安装我的 IDE pycharm。我将 python 安装到 C:\Program (x86)\python27。但是当我启动我的 gae 服务器时，我得到了这个回溯。什么意思？

如果我以管理员身份运行 pip install PyOpenSLL 然后我得到

新:

您似乎使用 LibreSSL 而不是 OpenSSL。参见 Python: Issue 21356

通过在 python-shell 中运行它来检查您是否正在使用 LibreSSL:

from ssl import OPENSSL_VERSION; print OPENSSL_VERSION

旧的:

File "C:\Program Files (x86)\Google\google_appengine\google\appengine\dist27\socket.py", line 73, in <module>
    from _ssl import RAND_add, RAND_egd, RAND_status, SSL_ERROR_ZERO_RETURN, SSL_ERROR_WANT_READ, SSL_ERROR_WANT_WRITE, SSL_ERROR_WANT_X509_LOOKUP, SSL_ERROR_SYSCALL, SSL_ERROR_SSL, SSL_ERROR_WANT_CONNECT, SSL_ERROR_EOF, SSL_ERROR_INVALID_ERROR_CODE
ImportError: cannot import name RAND_egd

是您必须知道的。用非常简单的写作，它意味着: “Google 的应用引擎无法在模块 _ssl 中找到名为 RAND_egd 的名称”

尝试更新所有包。

尝试从控制台from _ssl Import RAND_egd，然后将结果放在这里。
