如何用pypy创建virtualenv？

Question

运行以下命令

virtualenv -p /usr/local/bin/pypy pypy

退出时出现如下错误

Running virtualenv with interpreter /usr/local/bin/pypy
New pypy executable in pypy/bin/pypy
debug: WARNING: Library path not found, using compiled-in sys.path.
debug: WARNING: 'sys.prefix' will not be set.
debug: WARNING: Make sure the pypy binary is kept inside its tree of files.
debug: WARNING: It is ok to create a symlink to it from somewhere else.

ERROR: It thinks sys.prefix is u'/Users/myname' (should be u'/Users/myname/pypy')
ERROR: virtualenv is not compatible with this system or executable

我正在运行MacOSX10.8.1 (Mountain Lion)和CPython 2.7.3，并使用Brew安装了pypy 1.9。virtualenv的版本是1.8.4

使用直接从pypy网站下载的适用于Mac OS X的预建pypy二进制文件不会产生任何影响

Answer 1

在1.8.4中，这似乎是一种回归。当我在我的系统上尝试时，virtualenv 1.8.2一切正常，然后我升级了，现在我得到了和你一样的错误。

Answer 2

对windows来说，这对我很有效：

python -m virtualenv -p <Your PYPY installed path\pypy3.exe> <venv_name>

Answer 3

我在使用virtualenv 1.8.2的Windows上得到了同样的错误。1.9和1.10也有类似的问题。对我来说起作用的是运行它一次来创建目录，复制丢失的文件，然后再次运行以完成它。

virtualenv -p c:\bin\pypy\pypy.exe pypy
copy c:\bin\pypy\lib_pypy \virtualenvs\pypy
copy c:\bin\pypy\lib-python \virtualenvs\pypy
virtualenv -p c:\bin\pypy\pypy.exe pypy
