我做错了什么？我已经多次卸载并重新安装了 Strawberry Perl，使用了 MSI 安装程序，现在我正在尝试压缩文件。为什么它会在我的 C 盘上创建一个名为“C”的文件夹？ "C:\c\Users\Locals.cpan\"

这是最新版本的 Strawberry Perl x64 的示例输出，似乎已经成功：

我认为问题可能是您没有从 \perl\bin 目录运行 cpan。

【解决方案2】：

我很遗憾这么晚才给出答案，但我遇到了完全相同的问题，经过一些修补后，我想通了。

注意到该路径语法有一些熟悉的地方吗？它是 MSYS/MinGW/Git Bash 使用的那个。发生的事情是，在 MinGW 上，我用 /c/Users/<username>/.cpan 中的 Windows 主文件夹的符号链接替换了我的主文件夹。因此，当我在 MinGW 中启动 CPAN 时，它在 /c/Users/<username>/.cpan 中创建了我的配置，并用这种格式的路径填充它。

现在，从 Strawberry Perl 的角度来看，这意味着我在 C:\Users\<username>\.cpan 中有一个现有的 CPAN 配置。虽然这不是 CPAN for Strawberry Perl 写入其配置的位置（至少默认情况下不是），但如果此路径中存在 CPAN 配置，它将读取和写入它而不是默认位置。当然，此配置中的所有路径在 Windows 上下文中都没有意义。

因此：

如果您使用 MinGW、Git Bash、Cygwin 或任何其他类 UNIX 环境 Windows 并将其配置为使用您的 Windows 主文件夹作为您的 UNIX 主文件夹，撤消此配置。
重命名、移动，或者如果您确定不再需要它，请删除 C:\Users\<username>\.cpan。您可能可以将此目录从 Windows 主文件夹移动到 UNIX 主文件夹，以保留类 UNIX 环境中的配置和模块。我建议测试一下。
再次在 Strawberry Perl 中运行 CPAN。它将正确地自动配置自己。

【讨论】：

这帮助我解决了同样的问题。我之前在我的 Windows $HOME 中安装了 .cpan，它干扰了 StrawberryPerl。我删除了两个 .cpan 目录，从头开始，一切正常。谢谢。

【解决方案3】：

我通过.msi 安装程序将其安装到自定义位置，但由于某种原因，该路径未在内部重新配置。 Cpan 继续下载到 C:\straberry，即使那里没有安装 Perl。

幸运的是，这就是 relocation.pl.bat 的用途。下载 .zip 分发包，将批处理文件解压缩到我的 Perl 安装并运行它解决了问题。

阅读 Perl 安装附带的 README 文件以获取更多信息。
