cat requirements.txt
requests==2.22.0
pandas==0.24.2
I was getting a whole lot of errors. This was permission problem.
When I did sudo pip3 install -r requirements.txt there were no errors and Successfully installed pandas-0.24.2. I am on Ubuntu 20.04.1.
When on virtual environment, all packages get downloaded to /home/ubuntu/.virtualenvs/my-project/lib/python3.8/site-packages, then why the need for sudo ?
Whenever I use pip3 for eg I did pip3 install virtualenvwrapper-win
I get WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Also for this specific module virtualenvwrapper I am getting
ERROR: Could not find a version that satisfies the requirement virtualenvwrapper-win (from
versions: none)
ERROR: No matching distribution found for virtualenvwrapper-win
But installing anything with pip works fine it's just pip3 that's not working.
I searched askUbuntu for this and found this but the accepted answer to this is not working for me. More specifically if I do sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
I get E: Unable to correct problems, you have held broken packages.
Please help me to fix pip3.
Ubuntu 19.10 seems to have what feels like a somewhat non-standard virtualenvwrapper package which is causing me issues. But it does seem more sensible to install pip, virtualenv and virtualenvwrapper from a package than to pollute the global environment outside of the virtualenv.
Most instructions (e.g.) suggest to add the following to .bashrc:
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
source /usr/local/bin/virtualenvwrapper.sh
However, Ubuntu installs virtualenvwrapper.sh in /usr/share/virtualenvwrapper/:
$ dpkg -L virtualenvwrapper
/.
/usr
/usr/share
/usr/share/bash-completion
/usr/share/bash-completion/completions
/usr/share/bash-completion/completions/virtualenvwrapper
/usr/share/doc
/usr/share/doc/virtualenvwrapper
/usr/share/doc/virtualenvwrapper/README.txt
/usr/share/doc/virtualenvwrapper/copyright
/usr/share/man
/usr/share/man/man1
/usr/share/man/man1/virtualenvwrapper.1.gz
/usr/share/virtualenvwrapper
/usr/share/virtualenvwrapper/virtualenvwrapper.sh
/usr/share/virtualenvwrapper/virtualenvwrapper_lazy.sh
/usr/share/doc/virtualenvwrapper/README.Debian
/usr/share/doc/virtualenvwrapper/changelog.Debian.gz
/usr/share/man/man1/add2virtualenv.1.gz
...
/usr/share/man/man1/workon.1.gz
Fine, I can bodge it and source from that location instead, but README.Debian implies bash-completion should pick it up:
In contrast to the information in /usr/share/doc/virtualenvwrapper/html/index.html this package installs virtualenvwrapper.sh as /usr/share/virtualenvwrapper/virtualenvwrapper.sh the lazy version is installed as /usr/share/virtualenvwrapper/virtualenvwrapper_lazy.sh.
Virtualenvwrapper is enabled if you install the package bash-completion and enable bash completion support in /etc/bash.bashrc or your ~/.bashrc. The bash completion file in /etc/bash_completion.d/virtualenvwrapper sources the lazy version of virtualenvwrapper by default but can be configured to load the full version instead.
If you only want to use virtualenvwrapper you may just add
source /usr/share/virtualenvwrapper/virtualenvwrapper.sh
to your ~/.bashrc or ~/.zshrc.
My .bashrc already appears to already contain the necessary to enable bash completion support:
# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if ! shopt -oq posix; then
if [ -f /usr/share/bash-completion/bash_completion ]; then
. /usr/share/bash-completion/bash_completion
elif [ -f /etc/bash_completion ]; then
. /etc/bash_completion

I'm running a stock Ubuntu 19.10 VM sourced from osboxes.org inside VMWare Player on Windows 10.
I've been trying to work out how to edit the bash profile for the login shell in Ubuntu 18.04. Being new to linux and the forum being my friend, i found that it is located in .profile as oppose to bash_profile previously. I'm not sure which profile i should be amending as i cannot find bash_profile.
I'm trying to add a line for virtualenvwrapper so that it can be sourced every time a new terminal session is launched but it isn't working.
nano .profile
Then adding...
source .local/bin/virtualenvwrapper.sh
to the end
Saved and exited but it doesn't work. Have i missed something or do i have to add anything in the script?
Thanks as always.
/home/isaac/anaconda3/bin/python: Error while finding module specification for 'virtualenvwrapper.hook_loader' (ModuleNotFoundError: No module named 'virtualenvwrapper')
virtualenvwrapper.sh: There was a problem running the initialization hooks.
If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/home/isaac/anaconda3/bin/python and that PATH is
set properly.
How would I go about solving the above?
