折腾：
后然后继续：
➜ youtubeSubtitle source /Users/crifan/dev/dev_root/tensorflow/bin/activate
结果并没有出现：
“上面的 source 命令应该将提示符改成了下面这样：

再去试了试，还是不行，去看看内容：

➜ dev_root
所以去：
➜ dev_root cd tensorflow
➜ tensorflow source bin/activate
➜ tensorflow
结果还是不行。
virtualenv 激活 不起效果
新开了个终端，还是不行：
换个目录，还是不行：
➜ tensorflow virtualenv –system-site-packages /Users/crifan/dev/dev_root/virtualenv
New python executable in /Users/crifan/dev/dev_root/virtualenv/bin/python2.7
Also creating executable in /Users/crifan/dev/dev_root/virtualenv/bin/python
Installing setuptools, pip, wheel…done.
➜ tensorflow source ../virtualenv/bin/activate
virtualenv activate mac
再去试试，还是不行：
➜ dev_root cd tensorflow
➜ tensorflow ll
➜ tensorflow virtualenv venv
New python executable in /Users/crifan/dev/dev_root/tensorflow/venv/bin/python2.7
Also creating executable in /Users/crifan/dev/dev_root/tensorflow/venv/bin/python

➜ tensorflow source venv/bin/activate
virtualenv not work
python – Activating a virtual env not working – Stack Overflow
重启iTerm试试，问题依旧。
python – Active virtualenv is not working – Stack Overflow
Virtualenv’s `bin/activate` is Doing It Wrong

干脆重新卸载virtualenv再重装
结果卸载出错：

以为旧名字可能冲突，所以去重命名再去试试，还是不行：

或许本身已经生效了，但是看不出来？
毕竟：
activate后，是可以执行deactivate的，并且再次执行deactivate会提示找不到：
所以，暂时先假定已经正常激活了虚拟环境了
所以或许是无需解决？
