颤振 [！] 在 `Pods/.symlinks/plugins/helloworld/ios` 中找不到 `helloworld` 的 podspec

Question

我已经使用颤振有一段时间了。有一次，当我去编译时，我遇到了这个错误。我的代码似乎没有任何意义。我试图重新安装我的 cocoapods，但这并没有改变任何东西。有人有什么想法吗？

Answer 1

这个问题发生在我身上，因为我不得不重命名我正在开发的插件。在我开始开发插件之后，但在我能够上传之前，包名称已被使用（例如，plugin_oldname）。

我的解决方案是：

修复.podspec名称：

  mv ios/plugin_oldname.podspec ios/plugin_newname.podspec

修复podspec文件中s.name参数的值，并将plugin_oldname替换为plugin_newname。

  Pod::Spec.new do |s|
    # Changed to plugin_newname from plugin_oldname
    s.name             = 'plugin_newname'

原来我的 .yaml 文件中缺少一个依赖项。 现在一切正常 :) 我会把它留在这里，以防有人去寻找同样的错误
