CondaHTTPError-安装NLTK时发生SSL错误 [英] CondaHTTPError - SSL error while installing NLTK

问题描述

我正在尝试在Anaconda的Tensorflow环境中安装NLTK.我已经为Windows 7 pc使用了命令"conda install nltk".它给出了以下错误:

I am trying to install NLTK in my tensorflow environment of Anaconda. I have used the command "conda install nltk" for my windows 7 pc. It gives the following error:

 CondaHTTPError: HTTP 000 CONNECTION FAILED for url
 <https://repo.continuum.io/pkgs/r/win-32/repodata.json.bz2>
 Elapsed: -

 An HTTP error occurred when trying to retrieve this URL.
 HTTP errors are often intermittent, and a simple retry will get you on   your way.

 SSLError(MaxRetryError('HTTPSConnectionPool(host=\'repo.continuum.io\', port=443): Max retries exceeded with url: /pkgs/r/win-32/repodata.json.bz2 (Caused by SSLError(SSLError("bad handshake: Error([(\'SSL routines\', \'ssl3_get_server_certificate\', \'certificate verify failed\')],)",),))',),)

我的系统中还有一个附加证书.因此，我将证书哈希添加到anaconda/ssl的cert.pem文件中.它适用于Linux计算机，但Windows计算机仍会引发错误.我该怎么解决?

I have an additional certificate in my system. So I added the certificate hash to cert.pem file of anaconda/ssl. It worked for Linux machine, but windows machine still throws error. What can I do to solve this?

推荐答案

您仍然可以通过从Windows计算机上的浏览器中导出CA证书来使用ssl.

You can still make use of ssl by exporting the CA Certificate from a browser on the windows machine.

将证书保存到您可以访问的文件夹中，然后只需将.condarc文件中的ssl_verify值设置为证书的位置即可.

Save the certificate to a folder that you can access, and then simply set the ssl_verify value in your .condarc file to the location of the cert.

ssl_verify: C:\\conda_config\\certificates\\ca_cert.cer

这将使您非常轻松地从ssl保护中受益.

This will allow you to benefit from ssl protection quite easily.
