How to avoid Permission denied when using pip with virtualenv

Question

I attempt to deploy a Python package with pip in a virtual environment on an Ubuntu machine  but encounter a permission-related issue  For example    TestVirtualEnv test testServer    pip install markdown2   terminates by      error  could not create   home test virtualenvs TestVirtualEnv lib python3 3 site-packages markdown2 py   Permission denied   I can t sudo  since it will install the package globally  and not within the virtual environment  I chowned site-packages  ls shows only directories related to easy install  pip and setuptools  and nothing related to Markdown   How to deploy a package in a virtual environment with pip without encountering permission-related errors

I ve also had this happen  by accident  after creating a new venv while inside an existing virtual environment   an easy way to diagnose this would be to see where the python is symlinked to  i e  run   ls -l venv bin python   and make sure it points to the appropriate Python binary   For most systems this will be  usr bin python or  usr bin python3   while if it points to an existing virtual environment it ll be something like  home youruser somedir bin python   if it s the latter than I d suggest recreating the venv while making sure that you aren t  inside  any existing virtualenv  i e  run deactivate

Solution   If you created the virtualenv as root  run the following command   sudo chown -R your username your username path to virtuaelenv    This will probably fix your problem   Cheers

While creating virtualenv if you use sudo the directory is created with root privileges So when you try to install a package with non-sudo user you won t have permission to install into it  So always create virtualenv without sudo and install without sudo   You can also copy packages installed on global python to virtualenv    cp -r  lib python site-packages   virtualenv lib python site-packages

You did not activate the virtual environment before using pip   Try it with      your venv path    bin activate   And then use pip -r requirements txt on your main folder

If you created virtual environment using root then use this command  sudo su   it will give you the root access and then activate your virtual environment using this  source  root  env ENV NAME bin activate

I didn t create my virtualenv using sudo  So Sebastian s answer didn t apply to me  My project is called utils  I checked utils directory and saw this   -rw-r--r--   1 macuser  staff   983  6 Jan 15 17 README md drwxr-xr-x   6 root     staff   204  6 Jan 14 36 utils egg-info -rw-r--r--   1 macuser  staff    31  6 Jan 15 09 requirements txt   As you can see  utils egg-info is owned by root not macuser  That is why it was giving me permission denied error  I also had to remove  Users macuser  virtualenvs armoury lib python2 7 site-packages utils egg-link as it was created by root as well  I did pip install -e   again after removing those  and it worked

virtualenv permission problems might occur when you create the virtualenv as sudo and then operate without sudo in the virtualenv   As found out in your question s comment  the solution here is to create the virtualenv without sudo to be able to work  esp  write  in it without sudo
