debian - Python 3.5 install pyvenv -

i trying virtual environment repo requires python 3.5. using debian, , can tell, python 3.5 not have aptitude package. after reading posts, recommended download 3.5 source code , compile it.

after running make , install, python3.5 installed /usr/local/bin. added $path variable.

here ran problems. after ran:

$ cd project-dir $ pyvenv env $ source env/bin/activate $ pip install -r requirements.txt 

i getting issues needing sudo install proper packages. ran:

$ pip 

and turns out pip still using /usr/local/bin version of pip.

$ echo $path 

returned

/home/me/project-dir/env/bin:/usr/local/bin:/usr/bin:/bin: ... 

i assuming because /usr/local path came after virtual environment's path in path variable, using version of pip instead of virtual environments.

what best way run correct version of pip within virtualenv? 2 options can think of moving binaries on /usr/bin or modifying activate script in virtual env place virtualenv path after /usr/local.

option 1 can upgrade pip in virtual environment manually executing

pip install -u pip 

option 2 method upgrade pip inside package python -m ensurepip --upgrade indeed upgrade pip version in system (if lower version in ensurepip).

you facing problem, because venv uses ensurepip add pip new environments:

unless --without-pip option given, ensurepip invoked bootstrap pip virtual environment.

ensurepip package won't download internet or grab files anywhere else, because required components included package. doing add security flaws , unsupported.

ensurepip not designed give newest pip, "a" pip. newest 1 use manual way @ beginning of post.

to check ensurepip version can type python console import ensurepip print(ensurepip.version())
