pip用命令更新所有包

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

vboxapi的pip打印错误

  Downloading/unpacking vboxapi

我可以说pip在更新时忽略vboxapi吗？
我试过命令

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

解决方法:

是的,您可以忽略这样的vboxapi包.

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

> -P标志告诉grep使用perl兼容的正则表达式.
> -v标志表示只列出与后面的正则表达式不匹配的那些.
>正则表达式匹配以-e或vboxapi =开头的行

您想要完成的完整示例：

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