错误而完全更新PIP封装

Question

虽然PIP更新命令所有包

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

皮普与vboxapi

Downloading/unpacking vboxapi 
    Could not find any downloads that satisfy the requirement vboxapi 
    Some externally hosted files were ignored (use --allow-external vboxapi to allow). 
    Some insecure and unverifiable files were ignored (use --allow-unverified vboxapi to allow). 
Cleaning up... 
No distributions at all found for vboxapi 
Storing debug log for failure in /Users/rmuhamedgaliev/.pip/pip.log 

打印错误我能说PIP忽略vboxapi而更新？ 我试着命令

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 

Answer 1

是的，你可以忽略vboxapi包这样。

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

• 的-P标志告诉grep来使用Perl兼容的正则表达式。
• -v标志说只列出那些做不是匹配下面的正则表达式。你想实现什么
• 正则表达式匹配以-e或vboxapi=

完整的示例开始为线：

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