Problem :
pip install -r requirements.txt
fails with the exception below OSError: [Errno 13] Permission denied: '/usr/local/lib/...
. What’s wrong and how do I fix this? (I am trying to setup Django)

Solution :
Rather than using sudo
with pip install
, It’s better to first try pip install --user
. If this fails then take a look at the top post here.
The reason you shouldn’t use sudo
is as follows:
When you run pip with sudo
, you are running arbitrary Python code from the Internet as a root user, which is quite a big security risk. If someone puts up a malicious project on PyPI and you install it, you give an attacker root access to your machine.
Option a) Create a virtualenv, activate it and install:
virtualenv .venv
source .venv/bin/activate
pip install -r requirements.txt
Option b) Install in your homedir:
pip install --user -r requirements.txt
My recommendation use safe (a) option, so that requirements of this project do not interfere with other projects requirements.
You are trying to install a package on the system-wide path without having the permission to do so.
-
In general, you can usesudo
to temporarily obtain superuser
permissions at your responsibility in order to install the package on the system-wide path:sudo pip install -r requirements.txt
Find more aboutsudo
here.Actually, this is a bad idea and there’s no good use case for it, see @wim’s comment.
-
If you don’t want to make system-wide changes, you can install the package on your per-user path using the
--user
flag.All it takes is:
pip install --user runloop requirements.txt
-
Finally, for even finer grained control, you can also use a virtualenv, which might be the superior solution for a development environment, especially if you are working on multiple projects and want to keep track of each one’s dependencies.
After activating your virtualenv with
$ my-virtualenv/bin/activate
the following command will install the package inside the virtualenv (and not on the system-wide path):
pip install -r requirements.txt
Just clarifying what worked for me after much pain in linux (ubuntu based) on permission denied errors, and leveraging from Bert’s answer above, I now use …
$ pip install --user <package-name>
or if running pip on a requirements file …
$ pip install --user -r requirements.txt
and these work reliably for every pip install including creating virtual environments.
However, the cleanest solution in my further experience has been to install python-virtualenv
and virtualenvwrapper
with sudo apt-get install
at the system level.
Then, inside virtual environments, use pip install
without the --user
flag AND without sudo
. Much cleaner, safer, and easier overall.
User doesn’t have write permission for some Python installation paths. You can give the permission by:
sudo chown -R $USER /absolute/path/to/directory
So you should give permission, then try to install it again, if you have new paths you should also give permission:
sudo chown -R $USER /usr/local/lib/python2.7/
If you need permissions, you cannot use ‘pip’ with ‘sudo’.
You can do a trick, so that you can use ‘sudo’ and install package. Just place ‘sudo python -m …’ in front of your pip command.
sudo python -m pip install --user -r package_name
So, I got this same exact error for a completely different reason. Due to a totally separate, but known Homebrew + pip bug, I had followed this workaround listed on Google Cloud’s help docs, where you create a .pydistutils.cfg file in your home directory. This file has special config that you’re only supposed to use for your install of certain libraries. I should have removed that disutils.cfg file after installing the packages, but I forgot to do so. So the fix for me was actually just…
rm ~/.pydistutils.cfg
.
And then everything worked as normal. Of course, if you have some config in that file for a real reason, then you won’t want to just straight rm that file. But in case anyone else did that workaround, and forgot to remove that file, this did the trick for me!
It is due permission problem,
sudo chown -R $USER /path to your python installed directory
default it would be /usr/local/lib/python2.7/
or try,
pip install --user -r package_name
and then say, pip install -r requirements.txt
this will install inside your env
dont say, sudo pip install -r requirements.txt
this is will install into arbitrary python path.
