Whenever I run pip install <PACKAGE-NAME>. cmd throws an error. It is only when I run pip install <PACKAGE-NAME> --user the command prompt works properly without any error.

For instance, when I run pip3 install runway-python I get, ERROR:

Exception: Traceback (most recent call last): File "c:\program files (x86)\microsoft visual studio\shared\python37_64\lib\site-packages\pip_internal\cli\base_command.py", line 186, in _main status = self.run(options, args) File "c:\program files (x86)\microsoft visual studio\shared\python37_64\lib\site-packages\pip_internal\commands\install.py", line 258, in run isolated_mode=options.isolated_mode, File "c:\program files (x86)\microsoft visual studio\shared\python37_64\lib\site-packages\pip_internal\commands\install.py", line 604, in decide_user_install if site_packages_writable(root=root_path, isolated=isolated_mode): File "c:\program files (x86)\microsoft visual studio\shared\python37_64\lib\site-packages\pip_internal\commands\install.py", line 549, in site_packages_writable test_writable_dir(d) for d in set(get_lib_location_guesses(**kwargs)) File "c:\program files (x86)\microsoft visual studio\shared\python37_64\lib\site-packages\pip_internal\commands\install.py", line 549, in test_writable_dir(d) for d in set(get_lib_location_guesses(**kwargs)) File "c:\program files (x86)\microsoft visual studio\shared\python37_64\lib\site-packages\pip_internal\utils\filesystem.py", line 140, in test_writable_dir return _test_writable_dir_win(path) File "c:\program files (x86)\microsoft visual studio\shared\python37_64\lib\site-packages\pip_internal\utils\filesystem.py", line 153, in _test_writable_dir_win fd = os.open(file, os.O_RDWR | os.O_CREAT | os.O_EXCL) PermissionError: [Errno 13] Permission denied: 'c:\program files (x86)\microsoft visual studio\shared\python37_64\Lib\site-packages\accesstest_deleteme_fishfingers_custard_1epdye'

it's fine when I append the code with --user. is there a way to fix this? I mean so that I don't have to append every pip install command with a --user.

Your python installation (which seems to have come with visual studio) is under 'c:\program files (x86), which is by default only writeable with admin privileges. In order to get your pip install working, you will need to launch your cmd with admin privileges.

  • I tried cmd with admin privileges. It worked fine. do you have any other solution other than opening cmd in admin mode? – user435715 Apr 15 '20 at 14:42
  • If you don't want to use `--user` each time and don't want to bother opening in admin mode each time, I only see two other ways: Modify the security settings so normal users have rw rights on `c:\program files (x86)\microsoft visual studio\shared\python37_64` OR uninstall the visual studio python installation and instead download and install python yourself and install it for your user only – FlyingTeller Apr 15 '20 at 14:48
  • I don't want to recommend to mess with your security settings, so I would see option 2 as my recommendation if you want to get rid of bothering with the restrictions – FlyingTeller Apr 15 '20 at 14:49

I suggest uninstalling and reinstalling pip:

sudo apt remove python-pip
sudo apt install python-setuptools
sudo easy_install -U pip

(Or the same with pip3 if that is what you're using)

  • OP is using windows, so no `sudo`, also, why do you think reinstalling will fix the issue that the `site-packages` requires admin privileges to write to – FlyingTeller Apr 15 '20 at 14:28
