将python虚拟环境链接到eclipse

Question

I have Python2.7 installed and Python3.5 installed on my windows machine.These are at locations C:\\Python27 and C:\\Python35-32. Both these are added in System Path environment variables and can be accessed from any directory.

Now i create a virtualenv in Python35-32 directory successfully under a sub-directory CODING_LABS. I try to link/point my Eclipse python interpreter to the python.exe file contained in CODING_LABS. This is done OK.

However, when i run my script from eclipse,it still points to Python27.Unable to figure out why?

Not sure... by default, any run will get the 'default' interpreter (which is the first interpreter in Preferences > PyDev > Interpreters > Python interpreter -- you may reorder those using the up/down button in that screen).

Now, that's the default, you may also configure to use a different interpreter per project (select project > alt+Enter for its properties > PyDev - Interpreter/Grammar > Interpreter).

Or you can choose a different one per launch: Menu > Run > Run Configurations > Select launch > Interpreter.

Also, you may want to double check to make sure that the paths in the interpreter configuration window (Preferences > PyDev > Interpreters > Python interpreter > select interpreter) actually map to the proper site-packages/external libs you expect.
