If you face this issue in Linux  one of the common reasons can be that the folder  anaconda3  or  anaconda2  has root ownership  This prevents other users from writing into the folder  This can be resolved by changing the ownership of the folder from root to  USER  by running the command   sudo chown -R  USER  USER anaconda3   or sudo chown -R  USER  USER  lt path of anaconda 3 2 folder gt   Note  How to figure out whether a folder has root ownership  -- There will be a lock symbol on the top right corner of the respective folder  Or right-click on the folder- properties and you will be able to see the owner details  The -R argument lets the  USER access all the folders and files within the folder anaconda3 or anaconda2 or any respective folder  It stands for  recursive

On Windows in general  running command prompt with administrator works  But if you don t want to do that every time  specify Full control permissions of your user  or simply all users  on Anaconda3 directory  Be aware that specifying it for all users allows other users to install their own packages and modify the content

As an alternative  I would suggest looking at your conda config file    Reason  Sometimes for creating a virtual env at a specified location other than the pre-defined path at   anaconda3 envs we append the conda config file using  conda config --append envs dirs  path to envs where envs dirs is a specified function in config file for allocating different paths where conda can find your virtual envs  Removing a recently added path in this config file may solve the problem   Solution     gt  conda config --show envs dirs      envs dirs      -  home some recent path      remove this     -  home     anaconda3 envs   Note the value specifing a different directory other than the predefined location  and remove it using     gt  conda config --remove envs dirs  home some recent path   Now the config file envs dirs is set to default location of envs  Try creating a new env now

If you get this error under Linux when running conda using sudo  you might be suffering from bug  7267   When logging in as non-root user via sudo  e g  by   sudo -u myuser -i   conda seems to assume that it is run as root and raises an error   The only known workaround seems to be  Add the following line to your    bashrc   unset SUDO UID SUDO GID SUDO USER      or unset the ENV variables by running the line in a different way before running conda   If you mistakenly installed anaconda miniconda as root via sudo this can also lead to the same error  then you might want to do the following   sudo chown -R username  path to anaconda3   Tested with conda 4 6 14
