创建使用与机器默认 Python 不同的 Python 版本的 virtualenv 时出错,而机器上安装了 Anaconda。我创建了一个新的虚拟环境:
virtualenv --no-site-packages ~/graphlabcreate
source ~/graphlabcreate/bin/activate
当我需要 python2.7 时,这创建了一个带有机器默认 python2.6 的目录。然后,我在这里阅读并尝试:
virtualenv -p /usr/local/anaconda/bin/python2.7 ~/graphlabcreate
并收到以下错误:
Running virtualenv with interpreter /usr/local/anaconda/bin/python2.7
New python executable in /home/nancy/graphlabcreate/bin/python2.7
Not overwriting existing python script /home/nancy/graphlabcreate/bin/python (you must use /home/nancy/graphlabcreate/bin/python2.7)
/home/nancy/graphlabcreate/bin/python2.7: error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory
ERROR: The executable /home/nancy/graphlabcreate/bin/python2.7 is not functioning
ERROR: It thinks sys.prefix is u'/' (should be u'/home/nancy/graphlabcreate')
ERROR: virtualenv is not compatible with this system or executable
当我运行时也会发生同样的情况:
virtualenv -p /usr/local/anaconda/bin/python2.7 --no-site-packages ~/graphlabcreate
