[python] pip install: Please check the permissions and owner of that directory

While installing pip and python I have ran into a that says:

The directory '/Users/Parthenon/Library/Logs/pi' or its parent directory is not owned by the current user and the debug log has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want the -H flag.

because I now have to install using sudo.

I had python and a handful of libraries already installed on my Mac, I'm running Yosemite. I recently had to do a clean wipe and then reinstall of the OS. Now I'm getting this prompt and I'm having trouble figuring out how to change it

Before my command line was Parthenon$ now it's Philips-MBP:~ Parthenon$

I am the sole owner of this computer and this is the only account on it. This seems to be a problem when upgrading to python 3.4, nothing seems to be in the right place, virtualenv isn't going where I expect it to, etc.

If you altered your $PATH variable that could also cause the problem. If you think that might be the issue, check your ~/.bash_profile or ~/.bashrc

I also saw this change on my Mac when I went from running pip to sudo pip. Adding -H to sudo causes the message to go away for me. E.g.

sudo -H pip install foo

man sudo tells me that -H causes sudo to set $HOME to the target users (root in this case).

So it appears pip is looking into $HOME/Library/Log and sudo by default isn't setting $HOME to /root/. Not surprisingly ~/Library/Log is owned by you as a user rather than root.

I suspect this is some recent change in pip. I'll run it with sudo -H for now to work around.

basic info

• system: mac os 18.0.0
• current user: yutou

the key

1. add the current account to wheel group

sudo dscl . -append /Groups/wheel wheel $(whoami)

2. modify python package mode to 775.

chmod -R 775 ${this_is_your_python_package_path}

the whole thing

• when python3 compiled well, the infomation is just like the question said.
• I try to use pip3 install requests and got:

File "/usr/local/python3/lib/python3.6/os.py", line 220, in makedirs
    mkdir(name, mode)
PermissionError: [Errno 13] Permission denied: 
'/usr/local/python3/lib/python3.6/site-packages/requests'

• so i cd /usr/local/python3/lib/python3.6/site-packages, then ls -al and got:

drwxr-xr-x    6 root   wheel   192B  2 27 18:06 requests/

when i saw this, i understood, makedirs is an action of write, but the requests mode drwxrwxr-x displaied only user root can write the requests file. If add yutou(whoami) to the group wheel, and modify the package to the group wheel can write, then i can write, and the problem solved.

How to add yutou to group wheel? + detect group wheel, sudo dscl . -list /groups GroupMembership, you will find:

wheel                    root

the group wheel only one member root. + add yutou to group wheel, sudo dscl . -append /Groups/wheel wheel yutou. + check, sudo dscl . -list /groups GroupMembership:

wheel                    root yutou

modify the python package mode

chmod -R 775 /usr/local/python3/lib/python3.6

What is the problem here is that you somehow installed into virtualenv using sudo. Probably by accident. This means root user will rewrite Python package data, making all file owned by root and your normal user cannot write those files anymore. Usually virtualenv should be used and owned by your normal UNIX user only.

You can fix the issue by changing UNIX file permissions pack to your user. Try:

$ sudo chown -R USERNAME /Users/USERNAME/Library/Logs/pip
$ sudo chown -R USERNAME /Users/USERNAME/Library/Caches/pip

then pip should be able to write those files again.

pip install --user <package name> (no sudo needed) worked for me for a very similar problem.
