I've just installed compiledb , OS: RHEL6
pip install --user compiledb
running it from the command line doesn't work:
$ compiledb
tells me that no compiledb command found.
I also tried
python comppiledb
the error was something like compiledb is not a script.
probably I should manually add user site-packages directory to some (?) path? what is a right way?
I know that's newbie question, but I couldn't find similar problem by googling.
and - yes, I don't know python just need (compildb) to convert makefile to compilation database, not more.
Let's look at the second case first. Try adding the -m flag when you run it with python:
python -m compiledb
To get it running as compiledb you probably need to add the pip user binary directory to your PATH. Let's see where pip install --user puts libraries on your machine. Run this on the command line:
python -c 'import site; print(site.USER_BASE)'
On my system this prints
/home/chris/.local
and binaries installed via pip install --user live in
/home/chris/.local/bin
Assuming you get similar output, you should be able to run compiledb as
/home/amigo421/.local/bin/compiledb
If that works you may want to add /home/amigo421/.local/bin to your PATH, e.g. by adding something like
export PATH="$PATH:/home/amigo421/.local/bin"
to your ~/.bash_profile then logging out and back in again. At that point you should be able to simply run
compiledb

I have been trying to install pyinstaller in order to create an executable of a python project I have been working on, but my pip command simply doesn't work. This is the error I would get "'pip' is not recognized as an internal or external command, operable program or batch file". I have already checked the interpreter of my pycharm project, and it shows that it has pip already installed. I tried to look this up online, and I found out that a problem could be that the environment variable Path just needs to have the directory of my python version, but even after doing this, it still would not work. For additional information, I already tried to find the directory by using the command "where python" in the command prompt, but that path didn't work, and I'm using windows 10.
Usually for most of users, there would be a problem as you mention above. In such situation, you just need to install pip again with command like
python -m pip3 install -U pip
and remember next time, if pip reminds you to upgrade it, do not just use
pip install -U pip
I encounter a problem when installing pip for python2.7. I downloaded the file get-pip.py, and install it successfully:
bogon:haha itensb$ python get-pip.py
Requirement already up-to-date: pip in /Library/Python/2.7/site-packages
Cleaning up...
But when I run the command pip, I got:
-bash: pip: command not found
I think it is the PATH not set appropriatelly , But I new on Mac. I need your help , thanks!
Use python -m pip. If you want the pip command check out #user3282276's answer.
Sounds like your PATH variable is not set to include the location that pip was installed to. On Macs and other *nix like operating systems when you type a command in the command line, what is actually happening is the shell is trying to find the executable file in a predefined area, called the PATH variable. If you are interested check out this question, https://superuser.com/questions/284342/what-are-path-and-other-environment-variables-and-how-can-i-set-or-use-them.
You are able to see what yours is set to if you do this in your command line
echo $PATH
this will give you some file paths separated by colons, for example when I type the command above I get this:
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/git/bin:/Applications/Android Dev Tool/sdk/tools
which means that my shell will check for a executable in each of these files, if it finds it, it will run otherwise it will tell you the program can't be found. As a side note this is the reason why when you run an executable not in one of these PATH files you must do,
./program
this is specifying a relative path to the executable file, the current directory that you are in.
So for you, you installed pip to this directory:
/Library/Python/2.7/site-packages
chances are the above echo statement did not include this file, if it did then you have another problem. What you need to do is to update your PATH variable to include this directory as well. To do this you add an export statement to your .bash_profile (or .bashrc on Linux) in your home directory (this is a hidden file) that includes your current path variables (so you will still be able to run everything installed in the proper place) and this new directory that you installed pip to. To do this add this line to the end of your .bash_profile
export PATH=${PATH}:/Library/Python/2.7/site-packages
and you should be good to go. However before it will take effect you need to close and open your terminal window again or run source .bash_profile. You can verify this worked by running the echo command above, it should return the same thing but this time with /Library/Python/2.7/site-packages appended to the end.
Note: By the way the which command that you were told to run in the comments locates a program within the users path, which is why it did not return anything to you. Also since you will probably run into this soon enough there is also a variable called PYTHONPATH (look here) which tells python where to look to import modules. You should set this to whatever directory you have pip installing modules to if it is not already set.
Install python3 first, then use pip3 to install packages.
brew install python
python3 will be installed, and pip is shipped with it. To use pip to install some package, run the following
pip3 install package
Notice it's pip3 because you want to use python3.
My same answer here
to run the command, it works
sudo easy_install pip
I recently installed python3 only to realize that mysql-python as well as many other modules were not well supported with it yet. So I changed the path in my bashrc file to point to an installation of python 2.7. The problem is that when I installed python 3 I also installed distribute and pip along with it. I removed the pip and distribute files from the python3 bin directory and installed setuptools and pip using python 2.7 however now when I use the pip command to install django and mysql-python, I get a bash error python331/bin/pip No such file or directory. It's still looking for pip in the python3 install. How can I remedy this?
Thanks
...I get a bash error python331/bin/pip No such file or directory.
It's still looking for pip in the python3 install. How can I remedy
this?
bash, by default, hashes the locations of commands to avoid searching $PATH each time, so if, when you execute...
$ type pip
...you get something like...
pip is hashed (python331/bin/pip)
...you just need to clear the hash table for bash with...
$ hash -r
...then it'll pick up the version in Python 2.7 the next time you try to run pip.
Fixed it.
Renamed the directory of where the python3 was installed, bash automatically looks for the next available python install python 2.7
In attempting to get started learning and developing python, I've tried to follow the Python Guide to installing python on OS X, but haven't found it particularly "noob friendly." I have a new MacBook (Mtn. Lion - OS X 10.8.3) wich comes with Python 2.7.2 built in. But the guide advises installing a "framework-style build" via homebrew. So:
I installed homebrew via ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
Then it tells you to add homebrew to the top of your PATH by adding it to your ~/.bashrc file. ls -a showed that I did not have a ~/.bashrc file in my home directory. After searching Stack Overflow on how to do that, I ran nano ~/.bashrc, and inserted the line export PATH=/usr/local/bin:$PATH to the file and saved the file.
I then ran brew install python --framework and the install completed.
Then, the guide says to "add the new Python scripts directory to your PATH" so, I'm assuming that means I need to add the line it provides to my ~/.bashrc file also. So, I added export PATH=/usr/local/share/python:$PATH to my ~/.bashrc file above my previous entry.
Finally, this is where I run into trouble, it says to easy_install pip. However, when I do that I get an error 13.
So, here are the things I need some help with.
Was I correct in my assumptions about how to add homebrew and python scripts to my PATH?
Did I do something wrong or do I just need to use sudo to install pip? (I'm really sorry if the answer is already on this page but even those answers don't make total sense to me and I want to be careful and not screw something up)
After installing the framework-style build of python (which I believe was the current 2.7.3), how come running python in my terminal still shows v2.7.2?
Thanks! I appreciate any help.
I've tried to follow the Python Guide to installing python on OS X,

Yes, I think it is misleading/outdated.
Then it tells you to add homebrew to the top of your PATH by adding it
to your ~/.bashrc file. ls -a showed that I did not have a ~/.bashrc
file in my home directory. After searching Stack Overflow on how to do
that, I ran nano ~/.bashrc, and inserted the line export
PATH=/usr/local/bin:$PATH to the file and saved the file.
On the Mac, just use ~/.profile
I then ran brew install python --framework and the install completed.
I think you don't need the --framework option unless you want to replace your Mac OS default installation and need an Mac OS Framework-style directory layout. There is no need to replace it though, the homebrew installation will take precedence anyway.
Then, the guide says to "add the new Python scripts directory to your
PATH" so, I'm assuming that means I need to add the line it provides
to my ~/.bashrc file also. So, I added export
PATH=/usr/local/share/python:$PATH to my ~/.bashrc file above my
previous entry.
Again, do it in ~/.profile. And don't forget to do a
source ~/.profile
otherwise the changes will only become active in any new terminal window, not the one you are currently using.
Finally, this is where I run into trouble, it says to easy_install
pip. However, when I do that I get an error 13.
The error shows that you try to install it your Mac OS system's default Python library (rather than in /usr/local, homebrew style), which would require root privileges. Just don't.
Also, with homebrew python, pip is already installed.
Check your path:
$ which pip
/usr/local/bin/pip
$ ls -l /usr/local/bin/pip
[..] /usr/local/bin/pip -> ../Cellar/python/2.7.3/bin/pip
Added bonus: Then do
pip install virtualenv
and use that.
And to your questions:
Was I correct in my assumptions about how to add homebrew and python
scripts to my PATH?
Yes, but use .profile and do a source .profile afterwards.
Did I do something wrong or do I just need to use sudo to install pip?
(I'm really sorry if the answer is already on this page but even those
answers don't make total sense to me and I want to be careful and not
screw something up)
You don't need sudo with homebrew, and pip is installed automatically with homebrew python.
After installing the framework-style build of python (which I believe
was the current 2.7.3), how come running python in my terminal still
shows v2.7.2?
Probably PATH not correct, do echo $PATH and check that it is correct. That is unrelated to being "framework-style" or not, though.
If you installed python with homebrew, you should already have pip installed. Try running
pip --version
to see whether and where pip is installed. Hopefully it's in a /usr/local/... path where your other homebrew things live.
Also before you install too much more with homebrew be sure to run these commands:
brew update
brew doctor
Good luck!
i'm trying to install a library for python of gene ontology programming [GOGrapher]. In the page they told me this:
$ `svn co https://projects.dbbe.musc.edu/public/GOGrapher/trunk GOGrapher`
$ cd GOGrapher
$ su -
# python setup.py install
I do everything, but in the last step a get an error
error: /usr/local/lib/python2.7/dist-packages/GOGrapher-0.0.egg-info: Permission denied
What is wrong? I'm new on this, but I do what I can.
Try
sudo python setup.py install
instead. (Works for me on Mac OS 10.7.3, while the suggested su - solution doesn't).
It is not a good idea to install things as superuser in the filesystem. In Python you can always install libraries locally.
Assuming you are already in GOGrapher directory:
$ python setup.py install --home
should install the library in your home directory. Later, you have to add the library PATH to the PYTHONPATH environment variable, so Python will know where to search for it.
$ export PYTHONPATH=$HOME/lib/python
The directory might be slightly different (lib/python2.7 or even lib/python2.7/site-packages), you can check it, tough.
To make it permanent, you should add it in your .profile, .bashrc, or whatever is the shell you are using.
