Question

我正在尝试在Windows 10计算机上使用numpy和openCV设置获取Python 3.6。我在pip 18.1中安装了python 3.6.8。当我尝试使用pip安装任何东西时，无论使用哪种软件包，都得到相同的结果：

C:\WINDOWS\system32>pip install numpy
Collecting numpy
  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x000001D135A3AE48>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed',)': /simple/numpy/

  Could not find a version that satisfies the requirement numpy (from versions: )
No matching distribution found for numpy

我尝试更新pip，它告诉我它已经是最新的了。发生了什么事？

Answer 1

我知道了。这是我公司网络上的代理问题。在pip安装numpy后使用--proxy工作。

Answer 2

请尝试使用此代码

Answer 3

尝试此代码。这会将pypi.org和files.pythonhosted.org设置为可信主机，以忽略SSL错误。 pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org

此问题的答案：pip install fails with "connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:598)"

Windows上的Pip无法安装任何程序
