How to put psql on the path when using Postgres.app on OS X?

问题

I've installed Postgres93 on my Mac. I can open the application, and "Open psql" through the app which opens up a command line interface with psql.

However, when I type $ which psql nothing is returned. The installation path is /Applications/Postgres93.app. How do I make $ which psql show the correct result?

Mac OS X - Mavericks

PostgreSQL package, I'm not as sure about. I went here and downloaded it - http://postgresapp.com/

It appears that you installed Heroku's Postgres.app, which is a tool intended for throw-away testing and development. Add the contents of the bundle to your PATH by following the instructions in the Postgres.app documentation - see "command line tools".

I just had postgres installed and was not able to run the psql command until I ran the following command in my terminal:

export PATH="/Applications/Postgres.app/Contents/Versions/9.5/bin:$PATH"

Now the terminal knows where to find postgres when I use the psql command.

Remember to replace the version number '9.5' with your current version.

I had the same problem with nothing showing for the which psql command till I run the command below to resolve it. The command provided below is just a little tweak of what has already been provided by others here. The only difference is, instead of providing a specific postgres version number in the command, you can simply tell postgres to use the latest postgres version by simply running the following command:

export PATH="/Applications/Postgres.app/Contents/Versions/latest/bin:$PATH"

And now my terminal was able to find the path to postgres when I run which psql.

Hope this helps.

** Edited: to include a permanent fix, not just during your current session. **

I had this same problem, and also found a clear answer lacking in the docs.

To fix:

1. Download the new app, and follow the instructions to move it to the Applications folder

2. Add the new bundle to your path by typing the following in your Terminal (version number specific - mine is 9.4): PATH="/Applications/Postgres.app/Contents/Versions/9.4/bin:$PATH"

3. To fix the issue on a permanent basis, run the same line but with export in front: export PATH="/Applications/Postgres.app/Contents/Versions/9.4/bin:$PATH"

回答5:

I just experienced the same problem, and solved it by adding export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.4/bin to .bash_profile. Note that this line is version-specific, so be sure to check this line against your current version of Postgres.app.

On macos mojave i've added the following line on my ~/.profile :

export PATH=$PATH:/Library/PostgreSQL/10/bin

the psql command line client lies into this folder. i've used the enterprisedb installer.

On macOS Mojave these instructions work well:

1. If your Postgres has not been installed yet, I suggest you use the great "brew" package manager from here https://brew.sh/ :

   $ brew cask install postgres or you can install it usual way from the website

2. Put this to the bottom of your ~/.bash_profile file:

   export PATH="/Applications/Postgres.app/Contents/Versions/latest/bin:${PATH}"

3. Restart your terminal or restart your ~/.bash_profile directly with the command:

   $ . ~/.bash_profile

4. Verify your installation:

   $ psql --version

In Mac, there is a SQL Shell application already under /Applications/PostgresSQL try that

Also, you can run /Library/PostgreSQL/11/scripts/runpsql.sh
