While pip update all packages with command

Pip print error with vboxapi

Can i say pip ignore vboxapi while update? I tried commands

pip freeze --local | grep -v '^\-e' | cut -d = -f 1  | xargs pip install -U -I
pip freeze --local | grep -v '^\-e' | cut -d = -f 1  | xargs pip install -U -I --allow-external vboxapi

Answer 1

Yes, you can ignore the vboxapi package like this.

grep -Pv '^(?:\-e|vboxapi\=)'

• The -P flag tells grep to use perl-compatible regex.
• The -v flag says to only list those which do not match the regex that follows.
• The regex matches lines that begin with -e or vboxapi=

Full example for what you want to accomplish:

pip freeze --local | grep -Pv '^(?:\-e|vboxapi\=)' | cut -d = -f 1 | xargs -n1 pip install -U;
