python3_5 in PYTHON_TARGETS不在Gentoo工作吗？

Question

我已经将PYTHON_TARGETS="python2_7 python3_5 python3_4"添加到我的/etc/portage/make.conf中。

当尝试安装任何支持python目标的程序时，会发生以下情况：

sudo emerge --ask dev-python/google-api-python-client

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N     ] dev-python/httplib2-0.9.1  PYTHON_TARGETS="python2_7 python3_4 (-pypy) (-pypy3)" 
[ebuild  N     ] dev-python/pyasn1-modules-0.0.5-r1  PYTHON_TARGETS="python2_7 python3_4 (-pypy) (-pypy3)"

[ebuild  N     ] dev-python/rsa-3.2.3-r1  USE="{-test}" PYTHON_TARGETS="python2_7 python3_4 (-pypy) (-python3_5)" 
[ebuild  N     ] dev-python/oauth2client-2.0.1  USE="{-test}" PYTHON_TARGETS="python2_7 python3_4 (-pypy) (-python3_5)" 
[ebuild  N     ] dev-python/google-api-python-client-1.5.0  USE="{-test}" PYTHON_TARGETS="python2_7 python3_4 (-pypy)" 

Would you like to merge these packages? [Yes/No] 

如您所见，python3_5由于某种原因被禁用，我不知道如何修复它。我还尝试将python_targets_python3_5添加到我的USE标志中，但没有结果。

$ eselect python list
Available Python interpreters:
  [1]   python2.7
  [2]   python3.4
  [3]   python3.5 *

我应该怎么做才能启用python3.5标志支持？

Answer 1

我终于找到了解决这个问题的办法。

您需要编辑/usr/portage/profiles/base/use.stable.mask并注释掉以下几行：

python_targets_python3_5
python_single_target_python3_5

现在我们开始：

sudo emerge --ask dev-python/google-api-python-client

These are the packages that would be merged, in order:

[ebuild  N     ] dev-python/google-api-python-client-1.5.0  USE="{-test}" PYTHON_TARGETS="python2_7 python3_4 (-pypy)" 

UPDATE:此更改将被系统更新覆盖，因此您需要用以下行更新/etc/portage/profile/use.stable.mask：

-python_targets_python3_5
-python_single_target_python3_5
