How to create requirement.txt without all package versions

Right now my requirement.txt contains following package list: 

asgiref==3.2.3
beautifulsoup4==4.8.2
certifi==2019.11.28
chardet==3.0.4
Click==7.0
Django==3.0.2
idna==2.8
pytz==2019.3
requests==2.22.0
six==1.14.0
soupsieve==1.9.5
sqlparse==0.3.0
urllib3==1.25.7

I just want the package name only, so that pip3 always installs the latest version.

Solution

  • Use sed to remove version info from your requirements.txt file. e.g.

    sed 's/==.*$//' requirements.txt

    will give output

    asgiref
beautifulsoup4
certifi
chardet
Click
Django
idna
pytz
requests
six
soupsieve
sqlparse
urllib3

    and this can be piped into pip to do the install

    sed 's/==.*$//' requirements.txt | xargs pip install
