尝试pip安装flas时解释器错误

Question

我确实在根目录下安装了Flask，但是每当我更改目录并运行virutalenv venv试图通过pip install Flask安装Flask时，我会收到以下错误

bash: /home/phillipsk/rampup/sql/venv/bin/easy_install: /home/phillipsk/rampup/webapp/sql/venv/bin/python: bad interpreter: No such file or directory

下面是venv目录的内容

activate activate.csh activate.fish activate_this.py easy_install easy_install-2.7 pip pip2 pip2.7 python python2 python2.7

我可以运行/home/phillipsk/rampup/webapp/sql/venv/bin/python

然后python解释器打开

Python 2.7.6

这是的l-l

/home/phillipsk/rampup/webapp/sql/venv/bin/python

-rwxr-xr-x 1 root root 3349512 Aug 15 13:11 /home/phillipsk/rampup/webapp/sql/venv/bin/python

这是我尝试运行pip install flask

sudo pip install flask确实可以工作，但是不管运行了哪一个pip命令，我都立即进入python解释器，import flask都没有成功

Answer 1

ImageView img = (ImageView) findViewById(R.id.img1);

看起来id img1是RelativeLayoutout而不是ImageView

Answer 2

我希望你正在安卓系统中铸造一个RelativeLayout到ImageView。检查xml文件中的R.id.img1是什么

Answer 3

检查logcat，它显示此错误。 java.lang.ClassCastException: android.widget.RelativeLayout cannot be cast to android.widget.ImageView 在使用ImageView之前，请检查其id
