我正在尝试构建 cyanogenmod，但构建失败并显示以下内容。我在 /mnt 上的驱动器有足够的空间，但是 /tmp 所在的根分区空间较小，所以我假设在写入临时文件时会发生这种情况。
因此，我也想将此临时目录重定向到 /mnt 下的某个位置，如何在 cyanogenmod/Android 构建系统中执行此操作？我尝试设置TMP，TEMP但它们似乎没有任何效果。

更新：我找到了一种解决方法，方法是手动编辑/mnt/android/system/build/tools/releasetools/common.py和设置临时目录，如tmpdir = tempfile.mkdtemp(dir='/mnt/tmp')第 1299 行，根据文档mkdtemp应该使用TMPand TEMP，但这似乎对我不起作用！Python 版本为 2.7.6。
