I'm running into an issue installing a package that's reliant on ocamlfind but I'm getting an ocamlfind: command not found error when making.
I have installed ocamlfind with the ocaml package manager and have tried reinstalling using "opam reinstall ocamlfind".
I have also tried the 'eval opam config env' command to see if updates my bin.
Has anyone run into a similar issue/know what this might be caused by
The output when running the make:
make
ocamlfind ocamlc -pp "camlp4o -I lib/dcg -I lib/ipp pa_dcg.cmo pa_ipp.cmo" -w usy -thread -I lib -I lib/dcg -I lib/ipp -c semantics.ml
/bin/sh: ocamlfind: command not found
The output when trying ocamlfind
ocamlfind
-bash: ocamlfind: command not found
ocaml is installed
opam install ocamlfind
[NOTE] Package ocamlfind is already installed (current version is 1.5.5).
and when running the eval command
eval 'opam config env'
CAML_LD_LIBRARY_PATH="/home/centos/.opam/system/lib/stublibs:/usr/lib64/ocaml/stub libs"; export CAML_LD_LIBRARY_PATH;
MANPATH="/home/centos/.opam/system/man:"; export MANPATH;
PERL5LIB="/home/centos/.opam/system/lib/perl5"; export PERL5LIB;
OCAML_TOPLEVEL_PATH="/home/centos/.opam/system/lib/toplevel"; export OCAML_TOPLEVEL_PATH;
PATH="/home/centos/.opam/system/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/centos/.local/bin:/home/centos/bin"; export PATH;
I'm on a server running centos 7
This command
eval 'opam config env'
is almost assuredly a typo and was supposed to be
eval `opam config env`
though using $(...) instead is the modern equivalent and avoids this font-fact confusion
eval $(opam config env)
That being said that just sets the environment variables in the current shell session (and exports them for use by processes run by this shell session).
As such that needs to be run in every shell session that needs those set (including each line of the makefile that expects them to be set if the environment that runs make doesn't already have them set and exported).
try
sudo apt-get install ocaml-findlib

I am working on a Macbook Pro running MacOS Monterrey, and I'm following instructions to work in a virtual environment from this site. https://duncanleung.com/set-up-python-pyenv-virtualenv-poetry/
While I am able to create a virtualenv, I am unable to activate it.
On running pyenv activate my-env, I get this error message:
Failed to activate virtualenv.
Perhaps pyenv-virtualenv has not been loaded into your shell properly.
Please restart current shell and try again.
My zshrc file has this content:
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv virtualenv-init -)"
if command -v pyenv 1>/dev/null 2>&1; then
eval "$(pyenv init -)"
fi
PATH=$(pyenv root)/shims:$PATH
Result of which python:
/Users/abc/.pyenv/shims/python
Result of python -V: Python 3.9.9
What could be possible reasons for the virtualenv not activating?
I'm trying to install Perl modules Geo::ShapeFile and Math::Round but I keep coming across the same error and I can't find a solution that works. I've local::lib installed fine but its not being found or something? Am I doing it in the wrong place?
cian#cian-Aspire-5750:~/Documents/Math-Round-0.07$ make install

I notice in my directory '/usr/local/man' points to 'usr/share/man'. I dunno if this was an issue how to solve it. Thanks.
I've local::lib installed fine
No, you don't. The environment has clearly not by set by local::lib. Make sure the following in your login script:
eval "$(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)"
(Adjust the path to local::lib if needed.)
Log out and log back in or use the following to pick up the changes:
exec bash -l
If you want to install module systemwide (it's what you do), you should have root privileges. Try sudo make install or install modules locally.
Alternatively you may try a cpanm client, which handles local::lib installs either:
$ cpanm -l ~/ Geo::ShapeFile Math::Round
And then don't forget to adjust perl5lib var to see installed modules:
$ PERL5LIB=~/lib/perl5
I found that the most convenient way of installing virtualenv + virtualenvwrapper is by using virtualenvburrito.
Now I can manage to automate my pip installs in a vagrant provision by the following:
Line in Vagrantfile:
config.vm.provision :shell, :path => "bootstrap.sh"
Lines in bootstrap.sh:
curl -s https://raw.github.com/brainsik/virtualenv-burrito/master/virtualenv-burrito.sh | $SHELL
source /root/.venvburrito/startup.sh
cd /vagrant
mkvirtualenv my_project
pip install -r requirements.txt
Then I run vagrant ssh but then I have to run the following to access my virtual environment:
sudo -i
source /root/.venvburrito/startup.sh
workon my_project
I don't want to always have to run sudo -i and source /root/.venvburrito/startup.sh, I just want to be able to run workon my_project directly.
But
(I.) I can't seem to append source /root/.venvburrito/startup.sh to my ~/.profile and
(II.) even if it was appended to that file I'd get a permissionerror. I can't seem to change the permissions for any protected file either.
The best way to deal with (I.) and (II.) is to set the privileged attribute in the Vagrantfile to false.

I want to use plenv to have perl 5.16 in the docker image. apt-get only get 5.14.
plenv will install perl in $HOME/.plenv/versions/5.16.2/, and I need to append some lines into $HOME/.profile:
export PATH="$HOME/.plenv/bin:$PATH"
eval "$(plenv init -)"
Then run plenv shell 5.16.2 to swith to the new version.
But in Dockerfile, I need to write source $HOME/.profile && plenv shell 5.16.2 everyline before I run some perl commands. docker didn't exec $HOME/.profile, is it a no-login shell?
Though I could write such command before every RUN, how can I do this in CMD line?
Do docker can solve this by some setting?
You can use the ENTRYPOINT command to prepend something before each executions or you can simply move your .profile within your .bashrc.
Indeed, docker is a no-login shell, it will not run upstart, simply execute the requested process.
I have being using fabric to deploy an app with virtualenv. I was using fabric 1.4 and upgraded to 1.5.1 last week. My script stopped working.
It can't install the requirements. It seems it's not activating the virtualenv. In my code, I have:
with cd('%(path)s' % env):
with prefix('source bin/activate'):
run('pip install -U distribute')
I'm getting a permission denied error: error: could not delete '/usr/local/lib/python2.7/dist-packages/pkg_resources.py': Permission denied
The command being executed is:
Executed: /bin/bash -l -c "cd /var/www/myproject && source bin/activate && export PATH=\"\\$PATH:\\"/var/www/myproject\\" \" && pip install -U distribute"
If I ssh to the remote machine and run cd /var/www/myproject && source bin/activate && pip install -U distribute, it works just fine.
Why is my fabric script not working?
Thanks in advance
Instead of the serial approach with..
source bin/activate
pip install -U distribute
..directly use the pip executable of the virtualenv:
myenv/bin/pip install -U distribute
Although not exactly a solution, fabtools has a number of functions related to virtualenvs that are very handy. They do (almost) all of the hard work for you, and are probably worth using to check it isn't something else going wrong.
