构建cyanogenmod时如何设置临时目录

Question

我正在尝试构建cyanogenmod，但是构建失败，原因如下。我在/mnt上的驱动器有足够的空间，但是/tmp所在的根分区的空间较小，所以我假设这是在编写临时文件时发生的。在

因此，我想将这个临时目录重定向到/mnt下的某个地方，在cyanogenmod/Android构建系统中如何做到这一点？我试着设置TMP和{}，但它们似乎没有任何效果。在

更新：我通过编辑/mnt/android/system/build/tools/releasetools/common.py并在第1299行手动设置temp dir，根据文档，mkdtemp应该使用TMP和TEMP来手动设置temp dir，但是这似乎对我不起作用！Python的版本是2.7.6。在

要设置TMPDIR环境变量，请指定运行复制或发布程序的用户ID可以访问的目录。确保文件不能被其他用户标识删除。 例如，以下命令指定/home/repldba/tempfiles/目录： export TMPDIR=/home/repldba/tempfiles/
