我刚刚在电脑上做了一个 composer 级别的例行检查，得到了一些意想不到的消息：

Composer version 2.0.7 2020-11-13 17:31:06我决定最简单的做法是更新Composer，因为这个版本已经有2年了，所以我运行了命令来更新，但是得到了同样的反对消息和一个实际的错误：

Upgrading to version 2.4.4 (stable channel).
[Composer\Downloader\FilesystemException]
Filesystem exception:
Composer update failed: "C:\ProgramData\ComposerSetup\bin\composer.
phar" could not be written.

self-update [-r|--rollback] [--clean-backups] [--no-progress] [--update-keys] [--stable] [--preview] [--snapshot] [--1] [--2] [--set-channel-only] [--] [<version>]重命名中涉及的两个文件都存在于C：\ProgramData\ComposerSetup\bin中，即composer.phar和composer-temp.phar，因此我认为错误是合理的：composer-temp.phar新名称已在使用中。
我该怎么做？将composer.phar重命名为composer.phar.old，然后再次尝试自我更新？还是会导致其他问题？

我该怎么做？将composer.phar重命名为composer.phar.old，然后再次尝试自我更新？还是会导致其他问题？
您可以尝试这样做，然后可能会发现composer命令不再运行（因为要执行的phar文件不在预期的位置），然后您可能会复制临时文件（显示在错误消息中），然后它可能已经工作了。
要点应该是：你不需要请求许可SO这样做，只要你记得你做了什么，并可以恢复以前的情况下，它没有计算，它是你的系统，你有控制（至少在一定程度上，因为它是Windows，但这是一个不同的东西）.
在您的
composer self-update期间（从弃用通知中减去噪声1），Composer遇到了一个没有您的干预就无法解决的情况，因此会告诉您：在Windows操作系统（OS）上，如果Composer是使用管理权限安装的，或者是由比执行
composer self-update命令的用户具有更高权限的用户安装的，则通常会出现这种情况。**信息：**在Windows上，文件可能会被锁定，直到下次重新启动系统。即使只使用更高级别的权限，也无法解除锁定，并且还需要重新启动（在适当的时间之前）。如果您关心此级别的详细信息，请查阅操作系统管理手册，了解为系统用户设置程序文件、应用程序及其数据所需的步骤。
使用所需权限执行
composer self-update命令（错误消息建议至少写入C:\ProgramData\ComposerSetup\bin\composer.phar）或使用在系统上设置composer的原始方式建议的更新过程（例如setup.exe、install.ini、MSI包、某些包管理器（如果正在使用）等）。由于您在问题中没有首先提供您是如何安装Composer的，或者Composer是如何安装在该系统上的，因此无法更具体地写出在您的特定情况下是如何安装的。
就像你一样，我也会先用
composer self-update，然后当得到这个错误时，也许 * 假设 * 在设置composer时正在使用composer windows安装程序，然后使用该安装程序来更新（如果它提供）或重新安装。但是，如果没有检查这种设置是否真正在使用中摆在首位，否则我会做适当的更新 * 原始安装程序 *。Composer通常是一个漂亮的应用程序，因此重新安装通常应该这样做，Composer Windows安装程序处理了很多Windows特定的配置/设置事情，所以它增加了更多的帮助。但首先检查使用的是哪个安装程序，而不是你在同一个系统上 * 无意中 * 结束了两个不同的版本。
例如，可以检查安装程序是否可以在“程序”（Windows系统配置GUI中的一个）下卸载composer。它的好处是，如果安装程序提供了这样一个选项，不仅卸载，而且更新都有一个按钮可以点击。
**警告：**因此，完全重新安装系统可能是目前为止没有提到的最后一个选项，因为它会使原始配置无效，您可以从一个干净的石板“重新启动”。在这里只是作为一个警告提到它，以防读者可能会交叉这个想法，它是最昂贵的选项，应该避免，除非 * 所有 * 其他选项都不计算。
1.注册 * 过时通知中的噪音 *：您的php-cli ini配置中有display_errors，这些不是错误，只是信息或调试通知。在您的情况下，这意味着您已经将PHP更新到最新版本，只是工具与composer不完全一致。这可能会分散注意力，但只要只有弃用通知和警告，composer应该仍然可以正常工作。因此，这些消息看起来并不像是composer最初无法在您的系统上执行
self-update事务的原因。
