标签： mysql ruby-on-rails ruby bundle

我遇到了问题。当我尝试使用以下命令创建一个新的rails项目/应用程序时： rails new app -d mysql 或 rails new app 我收到以下错误消息。 我的电脑运行Windows 10,64位，我正在使用rails 4.2.4。如果您需要更多信息，请随时提出。 （我删除了我的名字，这就是为什么你只看到Documents \ Sider）

如果你的理由像我一样，这真是一个烦人的解决办法： 我的名字包括一个扩展的ASCII字符“ø”。当计算机在我的PC上设置我的帐户时，使用了那个。例如。 C：\用户\比约恩

。

修复：将文件夹和您的家庭帐户重命名为Bjorn。

在您的系统上创建另一个管理员帐户，您可以将该帐户重命名为c：\ users \ Bjorn \

以下是重命名帐户的方法：https://superuser.com/questions/495290/how-to-rename-user-folder-in-windows-8

我从来没有在用户名中使用扩展字符，但是当我几年前设置Win8并且有可能使用微软帐户时，向导选择了用户名。

似乎未设置您的环境变量。请按照link设置变量：

注意：建议不要在ruby on rails开发中使用 Window 。所以我建议使用Mac / Ubuntu作为ROR。这将真正让你的生活更轻松

我遇到了同样的问题。我没有找到确切的解决方案，但找到了一些解决方法。实际上，Windows上的Rails不是直接从Windows的环境变量而是从文件中获取环境变量：

C：\ RailsInstaller \ GIT中\等\简档

我创建了一个文件夹PHFetchResultChangeDetails *collectionChanges = [changeInstance changeDetailsForFetchResult:self.assetsFetchResults]; [collectionView performBatchUpdates:^{ NSIndexSet *removedIndexes = [collectionChanges removedIndexes]; if ([removedIndexes count]) { [collectionView deleteItemsAtIndexPaths:[self indexPathsFromIndexes:removedIndexes withSection:0]]; } NSIndexSet *insertedIndexes = [collectionChanges insertedIndexes]; if ([insertedIndexes count]) { [collectionView insertItemsAtIndexPaths:[self indexPathsFromIndexes:insertedIndexes withSection:0]]; } } completion:^(BOOL finished) { if (finished) { // Puting this after removes and inserts indexes fixes a crash of deleting and reloading at the same time. // From docs: When updating your app’s interface, apply changes after removals and insertions and before moves. NSIndexSet *changedIndexes = [collectionChanges changedIndexes]; if ([changedIndexes count]) { [collectionView reloadItemsAtIndexPaths:[self indexPathsFromIndexes:changedIndexes withSection:0]]; } } } 并在C:\Users\Test中使用它的路径来替换发生故障的真实主路径：

C:\RailsInstaller\Git\etc\profile

之后必须设置错误“HOME环境变量（或HOMEDRIVE和HOMEPATH）并指向目录（RuntimeError）”已经消失。

这通常是一个错误的决定，但真正的解决方案有点相似。

在我的情况下问题是关于不同的编码，我的真正的主路径包含西里尔字符，因为它们不是ASCII rbreadline.rb不理解它们 - 因为最近的一些时间。但早些时候没有这样的问题，我不知道发生什么事情会使编码麻烦出现。
