如何用pypy创建virtualenv？

Question

运行以下命令

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

退出与错误，如

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. 
'import site' failed 
AttributeError: 'module' object has no attribute 'prefix' 
ERROR: The executable pypy/bin/pypy is not functioning 
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 

我与CPython的2.7.3运行Mac OS X 10.8.1（山狮），并用啤酒安装pypy 1.9。 virtualenv中的版本是1.8.4

使用预建pypy二进制的Mac OS X直接从pypy的网站上下载并没有任何区别

Answer 1

这似乎是在1.8.4回归。在我的系统上试用这一切时，一切正常，与virtualenv 1.8.2，然后我升级，现在我得到同样的错误，你。

Answer 2

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。对我来说有效的是运行一次来​​创建目录，复制缺失的文件，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 

Answer 3

随着pypy-4.0.1的virtualenv 14.0.3，开箱我得到一个错误：

Q:\>c:\pypy\bin\virtualenv -p c:\pypy\pypy.exe my_pypy_virtualenv 
Already using interpreter c:\pypy\pypy.exe 
New pypy executable in Q:\my_pypy_virtualenv\bin\pypy.exe 
debug: OperationError: 
debug: operror-type: ImportError 
debug: operror-value: No module named UserDict 
ERROR: The executable Q:\my_pypy_virtualenv\bin\pypy.exe is not functioning 
ERROR: It thinks sys.prefix is u'q:\\' (should be u'q:\\my_pypy_virtualenv') 
ERROR: virtualenv is not compatible with this system or executable 
Note: some Windows users have reported this error when they installed Python for "Only this user" or have multiple versions of Python installed. Copying the appropriate PythonXX.dll to the virtualenv Scripts/ directory may fix this problem. 

搜索原pypy安装UserDict*，我发现UserDict.py在lib-python\2.7但在virtualenv的lib-python\2.7只有userdict.py而且没有大写的User文件。以其他解决方案为例，我删除了virtualenv的userdict.py并复制了原始User*文件，并重新命令virtualenv命令，并且运行时没有错误。
