After reinstalling today, there is still a post installation error. Can you ask me a question? ding@ding-desktop:~/prga$ ./envscr/install [INFO] Using 'git': /usr/bin/git [INFO] Using 'make': /usr/bin/make [INFO] Using 'cmake': /usr/bin/cmake [INFO] Using 'gcc': /usr/bin/gcc [INFO] Active 'pyenv' found.

Hi @dingzex sorry for the late reply.

The first log seems to suggest zlib is missing. The second log seems to suggest www.python.org is not accessible at the time of installation. Is it possible that your Ubuntu installation is missing certain packages or not connected to the network properly?

[dingzex]

Hello, thank you for your attention to my problem. According to your reminder, I reinstalled zlib before pyenv, but there are still the above problems. The network connection on my side should be normal, but the following problems are found: ding@ding-desktop:~/prga$ ./envscr/install [INFO] Using 'git': /usr/bin/git [INFO] Using 'make': /usr/bin/make [INFO] Using 'cmake': /usr/bin/cmake [INFO] Using 'gcc': /usr/bin/gcc [INFO] Active 'pyenv' found.

Hi @dingzex ,

A few things suspicous are:

• WARNING: The Python bz2 extension was not compiled. Missing the bzip2 lib?
• ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib?
• ERROR: pipenv 2021.5.29 requires certifi, which is not installed.

These are not really packages required by PRGA, but by pyenv, pipenv and python3. If they still do not work, you can install pyenv then pipenv on your own.

[angl-dev]

Two more things that may help:

• Always start with a clean repo after fixing any dependency problem and then run envscr/install, in case some partially-installed stuff are not cleaned up.
• As a reference, you can take a look at https://github.com/PrincetonUniversity/prga/runs/3197318509?check_suite_focus=true for the log of PRGA's CI installation on ubuntu 20.04

[dingzex]

Thank you very much for your help. I have successfully passed the compilation and can run completely.

Please give more advice on future study. thank you.

[angl-dev]

Cool! I'll close this issue for now. If you have other questions with regard to the use or development of PRGA, please open another issue.
