Using virtualenv with sublime text 2

问题:

I am using sublime text 2 for python development along with virtualenv!

The standard sublime text 2 build system uses the standard python install rather than my virtualenv where my packages are installed.

How can I get sublime text 2 to build using my virtualenv?

I currently use the terminal to activate my environment and run my scripts.

UPDATE: Never got it working, but seeing as i am using flask and it builds when you make a change, it's not a big issue

回答1:

Note comments about this solution being incorrect.

You have to edit your sublime-project file and add the following:

"build_systems":
[
    {
    "name": "Run Tests",
    "cmd": ["source", "/path/to/your/virtualenv/bin/activate"],
    "working_dir": "/path/to/to/you/django_project",
    "cmd": ["python", "manage.py", "test"]
    }
]

回答2:

You can also set the path for the build system to the bin directory of your virtualenv, like so:

"build_systems":
[
    {
        "selector": "source.python",
        "env": {"PYTHONPATH":"/Users/user/project"},
        "path":"/Users/user/work/myvirtualenv/bin:$PATH",
        "name": "Run virtualenv python",
        "cmd": ["python", "-u", "$file"],
        "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",

        "variants": [
            {   "name": "Run all Tests",
                "working_dir": "/Users/user/project",
                "cmd": ["nosetests"]
            } 
        ]
    }
]

This also allows other tools, like nose in the example, to find the correct python binary from the virtualenv.

In windows this works for me:

"build_systems":
[
    {
    "name": "Run Tests",
    "working_dir": "/path/to/to/your/django_project",
    "cmd": ["/path/to/your/virtualenv/bin/python.exe", "manage.py", "test"]
    }
]

Sublime's Build System supports variables which can be used with Sublime project files to make this a bit more portable across projects.

If your virtual environments are in a standard spot, create a new project file (Project -> Save Project As) into the root directory of your project just above your virtual environment directory. Then create a new build file with something like this:

{

    "cmd": ["$project_path/venv/bin/python", "-u", "$file"]

}

It seems to then pick up the rest automatically - the same as if you typed ./venv/bin/python from the command line - no need to mess with paths, environment variables, etc.

回答5:

I'm using Flask, but I think it's apply to nearly every case.
My actual build is like this, where "benicio" is the directory of my project:

{
    "cmd": ["source ~/projs/benicio/venv/bin/activate && python ~/projs/benicio/benicio_tests.py"],
    "shell": true
}

回答6:

Sorry to add yet another answer to this - but this caused me a large amount of grief figuring this out.

Not only do you need to make a build system like:

"build_systems":
[
{
    "name": "Maths",
    "env": {"PYTHONPATH":"/home/nebffa/Desktop"},
    "path":"$project_path/bin",
    "cmd": ["$project_path/bin/python3.3", "-u", "$file"]
}
]

but you HAVE to change a setting in Sublime Text - go to Tools --> Build System --> "Maths". In my case I need to choose "Maths" because that's what I named my build system. If you don't do this - Sublime Text does not use your build system!!

回答7:

I have just got sublime text 3 to working in a virtualenv. Although the OP specified ST2, there all likely more like myself who are using ST3. Thanks to user1248490 and Russell Beattie I arrived at the following:

{
    "shell_cmd": "$project_path/vi_sys_pkgs/bin/python3 -u \"$file\"",
    "path": "$project_path/vi_sys_pkgs/bin",
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

Note that "cmd" is now "shell_cmd" in ST3. See ST3 blog

回答8:

Under MAC OSX, this works for me

{
"cmd": ["/your/virtualenv/bin/python", "-u", "$file"]
}

What i did was keep it simple:

Went to root drive and created python folder:

sudo mkdir python

then went in there and created the virtualenv

virtualenv --no-site-packages virtualenvname

then created a newbuild in ST2 with the above command and it works

回答9:

This is what I have as a build system (assuming my virtualenv is created as a folder called 'env' in my current project directory). This at least means I don't need to constantly change the build system between projects:

{
   "cmd": ["env/bin/python", "-u", "$file"]
}

I saved this as a New Build System (Tools -> Build System -> New Build System).

I use this to build my Flask project. I have added the following code to my Project Settings: Project -> Edit Project

{
     "folders":
     [
          {
               "path": "/C/MyDev/chilinzb/"
          }
     ],
     "build_systems":
    [
        {
            "name": "Flask",
            // activate the specific virtualenv for the project
            "cmd": ["C:/MyDev/virtualenvs/env_chilinzb/Scripts/python", "$file"]
        }
    ]
}

and then I just switch to my run.py file and hit Ctrl+B

回答11:

this combination worked great:2 steps

1) add the 2 appropriate keys to the 'env' key. A) DJANGO_SETTINGS_MODULE B) PYTHONPATH

2) update cmd to reflect the version of python you want to use.

{

"env":{"DJANGO_SETTINGS_MODULE":"my_project.settings",
    "PYTHONPATH":"d:\\Projects\\virts\\my_project\\Scripts;d:\\Projects\\virts\\my_project\\Lib;d:\\Projects\\virts\\my_project\\Lib\\site-packages;D:\\Projects\\my_project"
    },
"cmd": ["c:/Python27/python.exe","$file"]
}

I have an answer for anyone who uses Heroku and uses their foreman tool, and it works great. Simply create a new build system like so:

{
    "cmd": ["foreman", "run", "python", "-u", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

This pulls in all of the environment variables available to Foreman, including your virtualenv's $PATH variable, which adds the virtualenv Python to your python path.

回答13:

source did not work for me inside the build on lubuntu. use '.' or dot instead of 'source'.

this did work:

{

    "env": {
    "DJANGO_SETTINGS_MODULE":"django_project_name.settings",
    "PYTHONPATH":"/home/my_username/current/django_project_name:/home/my_username/.virtualenvs/django_project_name/lib/python2.7:/home/my_username/.virtualenvs/django_project_name/lib/python2.7/site-packages/"
},
"working_dir":"$project_path",
"cmd":[". /home/my_username/.virtualenvs/django_project_name/bin/activate && python $file"],
"shell":true

}

回答14:

this worked for me:

{
    "cmd": ["C:/Users/user/virtualenvs/env1/Scripts/python.exe", "-u", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

saved build in:

"C:\Users\user\AppData\Roaming\Sublime Text 2\Packages\User\"

as

"Python_env1.sublime-build"

Select

Tools> Build System> Python_env1

done!

using windows 8.1, st2

Assuming you keep your project-specific virtualenv in an .env-folder on the top level of your project.

1. Sublime > Project > Save project as... (if you haven't already. This will allow you to set custom build options for the project

2. Project > Edit Project:

   {
      "folders":[
          {
              "path": ".",
              "folder_exclude_patterns": [".env"],
          }
      ],
      "build_systems":[
          {
              "name": "Run in VirtualEnv",
              "shell_cmd": "source $project_path/.env/bin/activate && python -u $file"
          }
      ]
   }
   

3. Tools > Build System > Run in VirtualEnv

4. Tools > Build

Please note that this was tested with Sublime Text 3.
