The virtualenvwrapper official documents ask me to add three lines to ~/.bash_profile, but I add three wrong lines to there, and then, there is an error looks like below after I reloaded by commandsource ~/.bash_profile
/Users/donald/.bash_profile:1: bad assignment
Can anyone tell me how to do and why? and if someone can teach me how to install virtualenvwrapper? I have spent a whole night working on this and fail.
The three wrong command lines are:
export WORKON_HOME=~/Envs
mkdir -p $WORKON_HOME
source /usr/local/bin/virtualenvwrapper.sh
It's just a simple question, I found the answer later.
After you add wrong command lines to .bash_profile , you can use the command lines below to get a easy-editing window
touch ~/.bash_profile
open -e ~/.bash_profile
then you will know how to do.
And...
If you are confused with installing virtualenvwrapper, have a look on this:
virtualenvwrapper.sh is not in /usr/local/bin, you can use the command line below to find where is it.
which virtualenvwrapper.sh
After that, you can copy the virtualenvwrapper.sh to /usr/local/bin or change the path after source command in the .bash_profile.
Remember to reload the .bash_profile with the command line below everytime you use virtualenvwrapper.
source ~/.bash_profile
Thanks~!

I followed the instructions carefully at http://jamie.curle.io/blog/installing-pip-virtualenv-and-virtualenvwrapper-on-os-x/
Restarted my terminal and typed mkvirtualenv, got a command not found
looked in /usr/local/bin and ls shows me:
brew powerpc-apple-darwin8-gfortran-4.2
charm tclsh8.5
django-admin.py tclsh8.6
django-admin.pyc virtualenv
gfortran-4.2 virtualenv-2.7
gfortran-uninstall virtualenv-clone
i686-apple-darwin8-gfortran-4.2 virtualenvwrapper.sh
node virtualenvwrapper_lazy.sh
pip wish8.5
pip2 wish8.6
So I know it's in the correct directory. I don't understand where I could have screwed up.
The linked article recommends adding the line source /usr/local/bin/virtualenvwrapper.sh to bash login profile file ~/.bash_login.
However,
~/.bash_login is rarely used.
it is NOT read if the much more common (on OS X) ~/.bash_profile also exists.
Thus,
Check if you have a ~/.bash_profile file
and, if so, add the line source /usr/local/bin/virtualenvwrapper.sh there.
My recommendation is to never use ~/.bash_login. If you find other content, there, also add it to ~/.bash_profile, and delete ~/.bash_login.
Alternatively, if you're looking for cross-platform compatibility, put all definitions in ~/.bashrc instead, and add only [[ -e ~/.bashrc ]] && . ~/.bashrc to ~/.bash_profile.
I'm a new python user. When I was installing postgresql and running the following order:
$vi ~/.bash_profile
Add PATH=/usr/pgsql-9.2/bin:$PATH before export PATH.
$source ~/.bash_profile
My terminal became very strange. It seemed that I could not logout of the .bash_profile environment. When I use any basic comments like cd, open, etc., something strange happens.
This is my output:
MynametekiMacBook-Air:~ Myname$ cd Documents/
-bash: dirname: command not found
MynametekiMacBook-Air:Documents Myname$ open ~/.bash_profile
-bash: open: command not found
MynametekiMacBook-Air:Documents Myname$ easy_install pip
-bash: easy_install: command not found
How would I fix this?
If you enter
$nano ~/.bash_profile
you will be able to edit your bash profile, you can remove the line that you added that is causing problems and try again, or see if there is a syntax error in what was entered. Once you've finished your edits you need to press ctl+o then enter to confirm and ctl+x to exit back to the bash prompt.
run /bin/mv ~/.bash_profile ~/.bp. Close your terminal. Reopen and look at the new .bp file with vim ~/.bp. Fix any errors and run mv ~/.bp ~/.bash_profile to revert.
Try export PATH=$PATH:/usr/pgsql-9.2/bin instead of Add PATH=/usr/pgsql-9.2/bin:$PATH. Because it looks like you made so your paths are being overwritten instead of being updated.
When running this in terminal:
$ curl -L https://get.rvm.io | bash -s
It seems to work fine, but in the Upgrade Notes at the end it says
* WARNING: You have '~/.profile' file, you might want to load it,
to do that add the following line to '/Users/steven/.bash_profile':
source ~/.profile
And I can't use RVM, getting the error
-bash: rvm: command not found'
I am pretty new to terminal and Ruby, so any help would be greatly appreciated.
When you install rvm its paths get added to ~/.bash_profile. RVM will warn you about this during installation as you noticed. You could run source ~/.profile each time you load the terminal, but that's a pain in the neck.
From the bash docs:
When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable.
What this means is that /.bash_profile is being run, and /.profile and /.bashrc are being ignored.
To resolve this just open .bash_profile and copy the rvm paths at the top and paste them at the top of your .bashrc file. Open a new terminal window and it should be working just fine.
You can either delete .bash_profile, if it's empty, or copy and paste the contents of ~/.profile into it if you choose to keep it.
Do as the instruction said.
From the RVM Troubleshooting page.
If your .bash_profile isn't being correctly loaded on OSX, you need to do one of three things:
Create a file named ~/.bash_profile and add the RVM source line there
Add the RVM source line to ~/.profile
In your terminal preferences, change the shell from the default of /usr/bin/login to /bin/bash.
So, check if you have /Users/steven/.bash_profile in your system. If it is present, open the file and add that line at end of file:
source ~/.profile
else create the file and add it.
I'm following a tutorial called Starting a Django 1.4 Project the Right Way, which gives directions on how to use virtualenv and virtualenvwrapper, among other things.
There's a section that reads:
If you're using pip to install packages (and I can't see why you wouldn't), you can get both virtualenv and virtualenvwrapper by simply installing the latter.
$ pip install virtualenvwrapper
After it's installed, add the following lines to your shell's start-up file (.zshrc, .bashrc, .profile, etc).
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/directory-you-do-development-in
source /usr/local/bin/virtualenvwrapper.sh
Reload your start up file (e.g. source .zshrc) and you're ready to go.
I am running Mac OSX, and don't know my way around the Terminal too well. What exactly does the author mean by shell's start-up file (.zshrc, .bashrc, .profile, etc)? Where do I find this file, so that I can add those three lines?
Also, what does he mean by reload your start up file (e.g. source .zshrc)?
I would appreciate a detailed response, specific to OSX.
You're probably using bash so just add these 3 lines to ~/.bash_profile:
$ cat >> ~/.bash_profile
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/directory-you-do-development-in
source /usr/local/bin/virtualenvwrapper.sh
^D
where ^D means you type Control+D (EOF).
Then either close your terminal window and open a new one, or you can "reload" your .bash_profile like this:
$ source ~/.bash_profile
If you use bash, it usually means ~/.bash_profile.
In Terminal and iTerm new shells are login shells by default, so ~/.bashrc is not read at all. If instructions written for some other platform tell you to add something to .bashrc, you often have to add it to .bash_profile instead.
If both ~/.profile and ~/.bash_profile exist, only .bash_profile is read. .profile is also read by other shells, but many of the things you'd add to .bash_profile wouldn't work with them.
From /usr/share/doc/bash/bash.html:
When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable.
[...]
When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists.
I have Anaconda install, so I add these 3 lines to ~/.bash_profile
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Documents/Python
source /Users/Username/anaconda3/bin/virtualenvwrapper.sh
and then reload profile by:
$ source ~/.bash_profile
I use an approach that I think is easy to maintain.
It also works well if you sometimes use Ubuntu systems, however I will be sure to address the OP's OSX requirement in my answer.
Create a .aliases file with your alias(es) in your home directory, e.g. ~/.aliases
Execute this file from your .bashrc file (this is executed each time for a new shell process) with source ~/.aliases. This is all you would actually need to do for Ubuntu btw.
On OSX call .bashrc from your ~/.profile file, i.e. have ~/.bash_profile contain: source ~/.bashrc
I don't know what has happened, but in my Terminal on Mac OSX 10.5 it can no longer find my sudo command, or find command, etc. They are there because if I put /usr/bin/sudo or /usr/bin/find it works fine...
My .bash_login file looks like this:
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin$PATH"
My .bash_profile file looks like this:
export PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:/Library/Python/2.5/site-packages/django_trunk/django/bin:/usr/local/mysql/bin:/usr/bin/sudo$PATH"
I'll say now, I don't really know what I'm doing with the Terminal. I'm just a beginner to it all, and I must of done something for the environment variables (is that what they're called?) to be lost. I presumed I'd just have to make sure the /usr/bin/ path is in my bash files, but they are, and it doesn't seem to work. Please help!
Also, when I do use the /usr/bin/find command, it says "Permission denied" to me, even though I am logged into Mac OSX as the System Administrator account. I don't understand.
Any help would be grand. Thank you - James
It looks like both of your PATH exports are malformed:
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin$PATH"
The end bit there won't work. It should be:
export PATH=/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin:$PATH
Notice the colon before '$PATH'? It's important ;)
Also, the double quotes are not necessary.
If this doesn't work, we will need more information. It is possible that something else is modifying your path even after your shell configurations are loaded.
Can you post the results of:
$ echo $PATH
Configuration files are not always a good indication of the current environment variables, since they are modified by many programs and files, all across your system. To see all of your environment variables, you can run:
$ env
This should fix the problem completely and permanently.
first, export environment paths by using below command in the terminal.
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
now you have the commands you want. (eg. try ls. You'll see the command is working). But this is only for the current session. If you close the terminal and open a new one, you will have the previous issue. To make this change permanent, use below command,
go to home directory
cd ~
open .bash_profile file in nano / vim (I'm using nano here)
nano .bash_profile
This will open up nano editor. In a new line, paste the following;
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:$PATH
press 'control'+'o' to save (WriteOut) and 'control'+'x' to exit nano.
All done ! Now try the commands.

I went trough the same issue and here is how I solved it.
First of all I reverted the file to its original doing this way
/usr/bin/nano ~/.bash_profile
In my case I was not able to make work any command alias. Even vi or vim didnt work without specifying the full path of that command.
If nano is not installed just replace nano in the command by the editor installed
After that just restart the computer. In my case as I said bellow I could not use any command. When trying to do /usr/bin/source ~/.bash_profile
that command failed. So I had to restart the OS and it worked
