在安装了Anaconda的计算机上,创建一个使用与机器默认Python版本不同的Python虚拟环境时出现了错误。
我创建了一个新的虚拟环境:
virtualenv --no-site-packages ~/graphlabcreate
source ~/graphlabcreate/bin/activate
我创建了一个目录,使用了默认的Python2.6版本,但我需要Python2.7版本。然后,我在这里阅读并尝试:
virtualenv -p /usr/local/anaconda/bin/python2.7 ~/graphlabcreate
但是,我收到了以下错误信息:
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
当我运行以下命令时,同样的事情也会发生:
virtualenv -p /usr/local/anaconda/bin/python2.7 --no-site-packages ~/graphlabcreate
