I can not use the conda utility anymore. I use it regularly since years but lately, since I installed the python module scp (with the command conda install scp, I don’t know if it matters) without anything visibly unusual, I get the error below whatever the command as soon as I use conda (conda install …, conda update …, conda uninstall …, … , the message is always the same):

An unexpected error has occurred. Conda has prepared the above report.
If submitted, this report will be used by core maintainers to improve
future releases of conda.
Would you like conda to send this report to the core maintainers?

I tried to look at my .condarc file and even removed it but it doesn't change the pb. Do you know what I can do to go back to a working conda ?

Downgrading to conda 4.5.5 fixed this for me.
And with a ranting hat on: This is the third time in the space of about 18 months that a conda update has resulted in an error that causes builds to fail, and there's been plenty of other issues too. I presume it will be fixed by the core conda people at some point, and maybe it is caused by a particular combination of third party dependencies, but one way or another conda always seems extremely buggy. There was once an update that caused conda install conda to delete itself!
DELETE to C:\Users\<YOUR_USERNAME>\.condarc and then update Conda. This will solve it in Windows.
conda update conda
thank you, that works ! in case the link grows old, here is the simplified copy:
- Navigate to your conda base environment, as given by conda info.
- Open the file lib/pythonX.Y/site-packages/conda/gateways/connection/init.py. Where X.Y is the python major-minor version.
Replace the function 'should_bypass_proxies_patched' with :
def should_bypass_proxies_patched(should_bypass_proxies_func, url, no_proxy=None): if url.startswith("file://"): return True try: return should_bypass_proxies_func(url, no_proxy) except TypeError: return should_bypass_proxies_func(url)
Okay. I was facing the same problem with the Anaconda 3 2018 ver. So what I did is that I used Anaconda prompt. It automatically links the base conda files to the required proxies. just type "conda --version" in the prompt to check the prompt. Then type "conda install numpy". Voila! you are done.
I have tried to solve this problem for some time now. Finally I figure out that you should use pip install instead of conda install. Normally we use pip install in windows command prompt and conda install in Anaconda Prompt. But for me I solved the problem by using pip install in Anaconda prompt. The output is shown below
I have the same issue, I just fixed it by
1.uninstall the anaconda and download latest version
2.create a new environment and try installing packages in that environment
I got the same problem and solved.
In Anaconda prompt,
use pip install scp, not conda install scp
Creating a new environment with the command
conda create --name myenv
worked for me!
