[Resolved] Installing cert-verifier

luvimperfection · November 14, 2018, 2:09pm

Hi, everyone. I’m a newbie here.
I was following this tutorial…

and I’m stuck while running

pip install .

I even did

pip3 install .

but this was no use too…

I’m a newbie to blockchain… could someone please help me?
(By the way, I have experience with python, java, and (very basic) linux but I have no experience with wallets.)

oh, by the way… self introduction
I am an engineering student in South Korea,
and I have faith in Blockchain that it could give transparency to many fields, especially education
I want to make a blockcert certificate for my university’s internal usage, maybe starting from some small certificates for vacational programs and camps for highschoolers…
BUT I’M STUCK please help me…

I’m not a Mac user, so I’m afraid I can’t give you too much detailed technical assistance with anything specific to that environment, but I asked someone who is. It sounds like there are occasional issues with scrypt on Mac, which may or may not help you out, but here’s the quick-and-dirty note on the subject: https://github.com/blockchain-certificates/cert-issuer#mac-scrypt-problems

Note that this is for cert-issuer and not cert-verifier, but they are both Python apps with similar requirements. Might help!

I’m a mac user and have had problems before running some of the blockcerts python projects on my local machine. For me, the solution was to run them in a virtual environment.

# Python virtual environment

We recommend using virtualenv [details](http://docs.python-guide.org/en/latest/dev/virtualenvs/) for your python development. 
 
1. Ensure virtualenv is installed
   ```bash
   pip install virtualenv
   pip -p python3 virtualenv // for python 3
   ```
2. Create a virtualenv for your project
   ```bash
   cd $project_home
   virtualenv venv
   ```

3. Activate the environment
   ```bash
   source ./venv/bin/activate
   ```
4. After you're finished, deactivate the environment by running

Try to give that a try, and run pip install . after doing the step: source ./venv/bin/activate

Just did it fresh on my machine and it worked, so it doesn’t appear that there’s any python dependency hell going on, which sometimes happens.

Hi aronning
Thank you for your help and sorry for late reply - I was busy doing some other stuff
And yesterday, thanks to your help, I fixed the bug!
I activated my virtualenv, used sudo pip, updated xcode command line tools, and these three led to success
