Unable To Use Conda With Anaconda 2018.2 On Windows

I just did a fresh installation of Anaconda 2018.2 on Windows 10. This anaconda version uses python v3.7. While running conda for updating conda update conda, I got the following e

Solution 1:

What worked for me was to copy these files from Anaconda3/Library/bin to Anaconda3/DLLs :

libcrypto-1_1-x64.dll

libssl-1_1-x64.dll

Solution 2:

Using Anaconda Prompt as Administrator worked for me. I have not tried the second solution (OpenSSL)

Solution 3:

I will answer my own question. I discovered 2 solutions.

First solution is to use Anaconda Prompt

Second solution is to install OpenSSL for Windows. The binaries can be downloaded here;

This binary worked for me. https://slproweb.com/download/Win64OpenSSL-1_1_1a.exe I am running 64-bit Windows 10.

Above solutions have been tested to work on my PC.

Solution 4:

I had a similar problem running conda on my work laptop behind a firewall. Create a .condarc config file in your home directory, typically 'c:\users\[your user id]', if one doesn't already exist. Add an entry to turn off SSL verification. Looks like this:

ssl_verify:false

Save the file and retry the conda command.

If this doesn't work and your computer is behind a firewall. Make sure the proxy server entries are also defined in the .condarc config file. Example:

proxy_servers:http:http://www.proxy.com:8080https:https://www.proxy.com:8080

Solution 5:

Adding <anaconda_or_miniconda_installation_directory>\Library\bin to the PATH environment variable is sufficient to solve this problem.
