完整更新pip软件包时出错

问题描述

pip使用命令更新所有软件包时

While pip update all packages with command

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

出现 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

我可以说pip在更新时忽略vboxapi吗?我尝试过命令

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

推荐答案

是的，您可以忽略vboxapi程序包.

Yes, you can ignore the vboxapi package like this.

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

• -P标志告诉grep使用与Perl兼容的正则表达式.
• -v标志表示仅列出与以下正则表达式不匹配的内容.
• 正则表达式匹配以-e或vboxapi=
开头的行
• 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=

要完成的操作的完整示例:

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