All the former answers seem to be outdated   conda activate was introduced in conda 4 4 and 4 6      conda activate  The logic and mechanisms underlying environment activation have been reworked  With conda 4 4  conda activate and conda deactivate are now the preferred commands for activating and deactivating environments  You   ll find they are much more snappy than the source activate and source deactivate commands from previous conda versions  The conda activate command also has advantages of  1  being universal across all OSes  shells  and platforms  and  2  not having path collisions with scripts from other packages like python virtualenv   s activate script    Examples  conda create -n venv-name python 3 6 conda activate -n venv-name conda deactivate   These new sub-commands are available in  Aanconda Prompt  and  Anaconda Powershell Prompt  automatically  To use conda activate in every shell  normal cmd exe and powershell   check expose conda command in every shell on Windows   References   How to Get Ready for the Release of conda 4 4 Conda 4 6 Release

Use cmd instead of Powershell  I spent 2 hours before I switched to cmd and then it worked   create Environment   conda create -n your environment name   see list of conda environments   conda env list   activate your environment   conda activate your environment name   That s all folks

If this happens you would need to set the PATH for your environment  so that it gets the right Python from the environment and Scripts  on Windows    Imagine you have created an environment called py33 by using   conda create -n py33 python 3 3 anaconda   Here the folders are created by default in Anaconda envs  so you need to set the PATH as   set PATH C  Anaconda envs py33 Scripts C  Anaconda envs py33  PATH    Now it should work in the command window   activate py33   The line above is the Windows equivalent to the code that normally appears in the tutorials for Mac and Linux     source activate py33   More info  https   groups google com a continuum io forum   topic anaconda 8T8i11gO39U  Does  anaconda  create a separate PYTHONPATH variable for each new environment

Though  Simba had a good answer at the time  a lot has changed in the conda env since 4 6  Conda activate  env-name  overthrew source activate  env-name  for good but not without it own challenges  conda activate oftentimes forces your environment to base and makes you see something like this   and throwing loads of error back at you  This can also be because auto activate base is set to True  You can check this by using the following command conda config --set auto activate base False source    bashrc  And to reactivate use this conda config --set auto activate base True source    bashrc

As you can see from the error message the paths  that you specified  are wrong  Try it like this   activate       temp venv test   However  when I needed to install Anaconda  I downloaded it from here and installed it to the default paths  C  Anaconda   than I put this path to the environment variables  so now Anacondas interpreter is used as default  If you are using PyCharm  for example  you can specify the interpreter there directly

For me  using Anaconda Prompt instead of cmd or PowerShell is the key   In Anaconda Prompt  all I need to do is activate XXX

Note that the command for activating an environment has changed in Conda version 4 4  The recommended way of activating an environment is now conda activate myenv instead of source activate myenv  To enable the new syntax  you should modify your   bashrc file  The line that currently reads something like  export PATH   lt path to your conda install gt  bin  PATH    Should be changed to     lt path to your conda install gt  etc profile d conda sh   This only adds the conda command to the path  but does not yet activate the base environment  which was previously called root   To do also that  add another line  conda activate base   after the first command  See all the details in Anaconda s blog post from December 2017   I think that this page is currently missing a newline between the two lines  it says     conda shconda activate base     This answer is valid for Linux  but it might be relevant for Windows and Mac as well
