It s treating the string application as your URL   This means your shell isn t parsing the command correctly   My guess is that you copied the string from somewhere  and that when you pasted it  you got some characters that looked like regular quotes  but weren t Try retyping the command  you ll only get valid characters from your keyboard  I bet you ll get a much different result from what looks like the same query  As this is probably a shell problem and not a  curl  problem  you didn t build cURL yourself from source  did you    it might be good to mention whether you re on Linux Windows etc

Windows consoles usually doesnt interpret double quotes correctly in a JSON array  so you can solve it adding a slash   before double quotes

In my case  it was a missing line break that added unneeded parameters due to a bad copy and paste  I followed a guide at https   pytorch org docs stable notes windows html include-optional-components which looks like this when you copy it right here without any editing   REM Make sure you have 7z and curl installed  REM Download MKL files  curl https   s3 amazonaws com ossci-windows mkl 2020 0 166 7z -k -O 7z x -aoa mkl 2020 0 166 7z -omkl  Output  C  Users Admin gt curl  quot https   s3 amazonaws com ossci-windows mkl 2020 0 166 7z quot  -k -O 7z x -aoa mkl 2020 0 166 7z -omkl      Total      Received   Xferd  Average Speed   Time    Time     Time  Current                                Dload  Upload   Total   Spent    Left  Speed  100  103M  100  103M  0     0  5063k      0  0 00 21  0 00 21 -- -- -- 5629k 0     0    0     0    0     0      0      0 -- -- --  0 00 01 -- -- --     0curl   6  Could not resolve host  7z 0     0    0     0    0     0      0      0 -- -- --  0 00 01 -- -- --     0curl   6  Could not resolve host  x  curl   6  Could not resolve host  mkl 2020 0 166 7z  There is actually a line break before  quot 7z quot   with  quot 7z quot  as the executable  and before  in addition to adding curl to your user PATH  you need to add 7z to the user PATH as well  for example with setx PATH  quot  PATH  C  Program Files 7-Zip  quot     REM Download MKL files curl https   s3 amazonaws com ossci-windows mkl 2020 0 166 7z -k -O 7z x -aoa mkl 2020 0 166 7z -omkl
