Question

创建使用与机器的默认Python不同的Python版本的virtualenv时出错，而在机器上安装了Anaconda。我创建了一个新的虚拟环境：

virtualenv --no-site-packages ~/graphlabcreate
source ~/graphlabcreate/bin/activate

我创建了一个目录，机器默认为python2.6，而我需要python2.7。然后，我读了here并尝试了：

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

当我跑步时也是如此：

virtualenv -p  /usr/local/anaconda/bin/python2.7  --no-site-packages ~/graphlabcreate

Answer 1

如果您使用的是Anaconda，则可以使用conda创建环境而不是virtualenv，使用conda create命令。

Answer 2

你能否简要介绍一下你如何安装这个版本的python。以及您尝试安装的操作系统。

如果你的Os默认是python2.6。然后你需要为其他更新版本的python进行alt安装（所以它不会与你的操作系统冲突），并创建到python的符号链接

如下所示

tar -zxvf Python-2.7.6.tgz

cd Python-2.7.6

./ configure --prefix = / usr / local --with-threads --enable-shared

make＆amp;＆amp;制作altinstall

ln -s / usr / local / bin / python /usr/bin/python2.7

echo＆＃39; / usr / local / lib＆＃39; ＆GT;＆GT; /etc/ld.so.conf.d/usr-python2.7.conf

LDCONFIG

之后，您尝试安装虚拟环境库，然后尝试现在正在做的事情。

希望你有一些想法。：）
