I try to install ccxt.pro via pipenv. I usually use python venv module to create virtual environment but I try to work with pipenv too.
In ccxt.pro documentation, package should be installed via pip3 over https or ssh. Via github user and password I am able to install it.
When I tried to install this library over pipenv, I receive Installation Failed error:
pipenv install git+https://github.com/kroitor/ccxt.pro.git#subdirectory=python
Installing git+https://github.com/kroitor/ccxt.pro.git#subdirectory=python…
WARNING: pipenv requires an #egg fragment for version controlled dependencies. Please
install remote dependency in the form git+https://github.com/kroitor/ccxt.pro.git#egg=<package-name>.
✘ Installation Failed
I install all dependencies from setup.py but the problem persist. Triead to apply this but it get stucked on Installing....
Questions:
How can I install ccxt.pro via pipenv?
Why am I not able to install it the same way like with pip install command?
I'm new to using Anaconda and recently installed jupyter labs on my computer. However, any time I try to build on my local Jupyter Labs instance I get the following error:

This happens anytime I try using this command (e.g. after installing anew extension). I have npm v6.4.1, nodejs v10.13.0, and yarn v1.22.0 installed in this environment according to conda. I'm running Jupyter lab 1.2.6.
Any feedback, suggestions or help would be greatly appreciated.
I believe I have found the problem. I consult for a company and I was using the computer they provided me (I'm an admin on the computer). When I followed the same steps on my personal computer, it worked with no issues.
I then switched over to a different, more open network at work and the build was able to complete without errors. Clearly there is something in the firewall or something that was preventing me from doing the build.
Not sure if you've fixed it, if not you may try the solutions below.
info There appears to be trouble with your network connection. Retrying...
This is a yarn related error that seems to suggest something wrong with your network. This can happen if the yarn was trying to connect via a proxy. You can try the following if this is the case.
npm config rm proxy
npm config rm https-proxy
It can also happen if your network is too slow. You can try increasing Yarn timeout.
yarn add <yourPackage> --network-timeout 100000
Source: https://github.com/yarnpkg/yarn/issues/4890
As indicated above this might be due to the fact that your company forces you to download everything over the proxy. Yarn (which is used to install npm) does not know your proxy details by default, so you need to create a .yarnrc file in your home directory (usually C:\Users\Username where you need to fill in your own username in windows, or simply ~/ on ubuntu).
In that file you need to specify your proxy settings as follows:
https-proxy "http://username:password#proxy.address.com:port"
strict-ssl false
Note no = sign in there and quotes around the address.
Then you'll be able to download the packages through your proxy.
I had the same issue. I have tried different versions of nodejs with different environments but couldn't solve the issue. I have checked the log files and found out that there was a problem with yarn cache so clearing the yarn cache solved my problem.
From the logs you can see:
info There appears to be trouble with your network connection.

I had the same issue, and disabling the firewall temporarily helped me to sort out part of the the issue, but then I finally got it with:
jupyter lab build --dev-build=False --minimize=False
I had a similar issue associated with Norton notification blocking jupyter.exe and some other programs while running 'jupyter lab build'. I resolved this issue by 'Turn off or turn on Data Protector' in Norton or disabling Auto-protect and smart-firewall each time running 'jupyter lab build'.
I faced similar issues and here are the solutions that works for me:
Installed latest version of nodejs and npm.
Manually installed latest version of yarn (download its msi installer instead of via cmd--> npm install --global yarn)
remove npm proxy via cmd:
npm config rm proxy
npm config rm https-proxy
Restarting the laptop
jupyter lab build --dev-build=False --minimize=False
Voila, it works flawlessly.

I'm trying to run Cypress tests on the Hosted Linux Pool for Azure Pipelines. Unfortunately, the Hosted Agent doesn't have all the dependencies for Cypress installed.
Running the documented apt-get doesn't work:

Running apt-get update takes forever (25 minutes and still not done).
Any clues on how to get Cypress working quickly on the Hosted Agent is welcome.
Note: I tried running on Windows, that works, fortunately, so I'm not completely blocked. But to use the Windows Agent I now have 2 agent phases which adds overhead due to artefact downloads and npm install overhead.
Solved the issue using a pre-pended Shell (Bash) task in VSTS agent phase prior to running Cypress:
apt-get -qq -y update
apt-get -qq -y install xvfb libgtk2.0-0 libnotify-dev libgconf-2-4 libnss3 libxss1 libasound2
My CircleCI builds started failing today and it looks like yarn is having trouble installing ember-cli. I tried locally and am suddenly getting the same error.
I recently upgraded to ember-cli 2.13.2, but I don't think that's related because builds were working after the upgrade.
Here's my console output:
~/code/my-app(master ✗) yarn global add ember-cli
yarn global v0.24.6

What is your Node version? I've tried installing by yarn Ember CLI 1.13 project and it failed because CoreObject required versions between 4 and 7. I've downgraded Node from 8 to 7 and it worked.
I figured out my issue. I was using a Docker image that uses the latest version of node. When node updated to 8, my Circle builds started using that. I ended up creating my own image that is pegged at version 6 and using that on Circle instead.
