Question

我使用的是RHEL 6.3并拥有2.6.6。我需要使用Python 2.7.6。我从源代码编译了python，安装了pip和虚拟环境。

现在我正以不同的方式尝试：

virtualenv-2.7 testvirtualenv
virtualenv --python=/usr/local/bin/python2.7 myenv

但是我得到了AssertionError。完整跟踪：

Answer 1

我遇到了同样的问题。我找到了什么以及如何解决它：

virtualenv 1.11版本存在问题： https://bitbucket.org/pypa/setuptools/issue/129/assertionerror-egg-info-pkg-info-is-not-a

我的解决方案：

再次启动安装，指定较旧版本的virtualenv。（1.10.1没问题）

/usr/local/bin/easy_install-2.7 virtualenv==1.10.1

然后您可以继续安装其余部分：

virtualenv-2.7 testvirtualenv

Answer 2

将virtualenv版本更改为1.10.1适用于RHEL 5.8

yum groupinstall "Development tools"
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel wget
wget http://python.org/ftp/python/2.7.6/Python-2.7.6.tgz
tar -xf Python-2.7.6.tgz 
cd Python-2.7.6
./configure --prefix=/usr/local
make && make altinstall
cd ..
wget https://pypi.python.org/packages/source/d/distribute/distribute-0.7.3.zip  --no-check-certificate
