我在我的/etc/portage/make.conf中添加了PYTHON_TARGETS =“python2_7 python3_5 python3_4”.
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!

Would you like to merge these packages? [Yes/No]
如您所见,python3_5由于某种原因被禁用,我不知道如何解决它.我还尝试将python_targets_python3_5添加到我的USE标志中,但它没有结果.
$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？
解决方法:
我终于找到了解决这个问题的方法.
您需要编辑/usr/portage/profiles/base/use.stable.mask并注释掉以下行：
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:
Calculating dependencies... done!
[ebuild R ] dev-python/six-1.10.0 PYTHON_TARGETS="python3_5*"
[ebuild R ] dev-python/setuptools-20.6.7 PYTHON_TARGETS="python3_5*"

[ebuild U ~] dev-python/pyasn1-0.1.9 [0.1.8] PYTHON_TARGETS="python3_5%*"
[ebuild N ~] dev-python/httplib2-0.9.2-r1 PYTHON_TARGETS="python2_7 python3_4 python3_5 -pypy -pypy3"

[ebuild N ] dev-python/linecache2-1.0.0 USE="{-test}" PYTHON_TARGETS="python2_7 python3_4 python3_5 (-pypy) (-pypy3)"
[ebuild N ] dev-python/traceback2-1.4.0 PYTHON_TARGETS="python2_7 python3_4 python3_5 (-pypy) (-pypy3)"
[ebuild N ] dev-python/rsa-3.2.3-r1 USE="{-test}" PYTHON_TARGETS="python2_7 python3_4 python3_5 (-pypy)"
[ebuild N ] dev-python/oauth2client-2.0.1 USE="{-test}" PYTHON_TARGETS="python2_7 python3_4 python3_5 (-pypy)"
[ebuild N ] dev-python/google-api-python-client-1.5.0 USE="{-test}" PYTHON_TARGETS="python2_7 python3_4 (-pypy)"
更新：此更改将被系统更新覆盖,因此您需要使用以下行更新/etc/portage/profile/use.stable.mask：
-python_targets_python3_5
-python_single_target_python3_5
