python - pip error: Bad interpreter when trying to run 'pip install ...' on OS X -


i trying install fresh version of virtualenv (there problem path python has stored in sys.executable) , turns out there problem seems related.

when try run pip install virtualenv, output:

-bash: /usr/local/cellar/python/2.7.10_2/bin/pip: /usr/local/opt/python3/bin/python3.4:  bad interpreter: no such file or directory

now original point in reinstalling virtualenv keep getting error when run virtualenv venv

traceback (most recent call last):   file "/library/python/2.7/site-packages/virtualenv.py", line 2363, in <module>     main()   file "/library/python/2.7/site-packages/virtualenv.py", line 832, in main     symlink=options.symlink)   file "/library/python/2.7/site-packages/virtualenv.py", line 994, in create_environment     site_packages=site_packages, clear=clear, symlink=symlink))   file "/library/python/2.7/site-packages/virtualenv.py", line 1288, in install_python     shutil.copyfile(executable, py_executable)   file "/usr/local/cellar/python3/3.4.3_2/frameworks/python.framework/versions/3.4/lib/python3.4/shutil.py", line 108, in copyfile     open(src, 'rb') fsrc: filenotfounderror: [errno 2] no such file or directory: '/usr/local/opt/python3/bin/python3.4'

as sidenote may relevant, rather using default installed python3, brew-installed python3 brewed openssl (an application required it) , placed path of brewed python3 @ top of /etc/paths.

i have tried install , uninstall python multiple times without success , @ loss of problem be. direction appreciated.

edit after @cel 's suggestions, turned out head of pip file (located @ /usr/local/cellar/python/2.7.10_2/bin/pip) set hardcode python version #!/usr/local/opt/python3/bin/python3.4. changed output of which python /usr/local/cellar/python/2.7.10_2/bin/python

this allowed me succesfully create virtualenv once again. thanks!

i came across similar problem when used homebrew upgrade python version 3.5.2 version 3.6.0. homebrew updated symlink /usr/local/bin/pip3 /usr/local/cellar/python3/3.6.0/bin/pip3 /usr/local/bin/pip still using old script , pointing python interpreter @ /usr/local/opt/python3/bin/python3.5.

my course of action follows:

  1. unlinked /usr/local/bin/pip , updated point /usr/local/cellar/python3/3.6.0/bin/pip3.

  2. created new symlink /usr/local/bin/pip3.5 pointed /usr/local/cellar/python3/3.5.2/bin/pip3 , updated header of pip3.5 script point python interpreter @ /usr/local/cellar/python3/3.5.2/bin/python3.5

  3. followed same procedure virtualenv.

p.s. didn't face problem virtualenv since using -p option.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
