Question

我正在尝试使用csv2svn将CSV存储库迁移到SVN。在第一次传递（CollectRevsPass）期间处理了一些错误之后，我在第四步中出现了这个错误：

MemoryError

我检查过，当出现此错误时，有足够的可用内存。就在Error出现之前，进程'python'会大量增加内存的使用。

有人知道我该怎么办？

CVS2SVN 2.4
Python 2.7

Answer 1

此错误还可能表示进程已用完虚拟地址空间。如果您在32位模式下运行cvs2svn，则该进程只能使用2 GiB或4 GiB的地址，无论计算机是否具有空闲RAM。如果是这种情况，请尝试以64位模式运行程序。

如果您已经在64位模式下运行，请尝试增加RAM或交换空间或在更强大的计算机上运行该程序。

MemoryError使用CVS2SVN
