我似乎无法在我的FreeBSD系统上安装Python 2.7.这是一些信息：

# portsnap update
Ports tree is already up to date.

版：

# uname -r
7.1-RELEASE

安装：

# cd /usr/ports/lang/python27/
# make
===>  Found saved configuration for python27-2.7.5_1
=> Python-2.7.5.tar.xz doesn't seem to exist in /usr/ports/distfiles/python.

任何帮助都非常感谢.

解决方法:

很可能是过时释放的症状.版本7具有较旧的tar包,无法处理.xz扩展名.可以通过从端口安装libarchive然后通过在/etc/make.conf中添加TAR = /usr/local/bin / bsdtar或通过符号链接到bsdtar来将libarchives tar设置为默认的tar二进制来实现解决方法.
