Question

通常，执行Do not run Composer as root/super user! See https://getcomposer.org/root for details时会遇到问题sudo composer require somePackage。

这是我安装swiftmailer的记录。
首先在没有composer require somePackage的情况下执行sudo。

debian9@machine:~$ composer require "swiftmailer/swiftmailer:^6.0"
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)

Installation failed, reverting ./composer.json to its original content.


  [RuntimeException]                                                           
  /home/debian9/vendor/doctrine/lexer does not exist and could not be created  
  .                                                                            


require [--dev] [--prefer-source] [--prefer-dist] [--no-progress] [--no-update] [--no-scripts] [--update-no-dev] [--update-with-dependencies] [--ignore-platform-reqs] [--prefer-stable] [--prefer-lowest] [--sort-packages] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--] [<packages>]...

让我们尝试sudo。

debian9@machine:~$ sudo  composer require "swiftmailer/swiftmailer:^6.0"
Do not run Composer as root/super user! See https://getcomposer.org/root for details
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
  - Installing doctrine/lexer (v1.0.1)
    Downloading: 100%         

  - Installing egulias/email-validator (2.1.6)
    Downloading: 100%         

  - Installing swiftmailer/swiftmailer (v6.1.3)
    Downloading: 100%         

egulias/email-validator suggests installing ext-intl (PHP Internationalization Libraries are required to use the SpoofChecking validation)
swiftmailer/swiftmailer suggests installing ext-intl (Needed to support internationalized email addresses)
swiftmailer/swiftmailer suggests installing true/punycode (Needed to support internationalized email addresses, if ext-intl is not installed)
Writing lock file
Generating autoload files

我很困惑，如果没有sudo，则无法安装swiftmailer，而有了sudo，则会发生Do not run Composer as root/super user!的错误。

您过去可能曾经使用sudo运行Composer。这已将某些目录保留在vendor/下，由root拥有，从而使您无法正常使用Composer。

将整个vendor目录的所有权更改为您的Shell用户，或完全删除该目录。（您将需要以root用户身份执行此操作。）完成后，您应该能够正常使用Composer。

用sudo还是什么时候执行“ composer require”命令？
