Error: “MSVCP90.dll: No such file or directory” even though Microsoft Visual C++ 2008 Redistributable Package is installed

问题

I'm trying to build a package from source by executing python setup.py py2exe

This is the section of code from setup.py, I suppose would be relevant:

if sys.platform == "win32": # For py2exe.
    import matplotlib
    sys.path.append("C:\\Program Files\\Microsoft Visual Studio 9.0\\VC\\redist\\x86\\Microsoft.VC90.CRT")
    base_path = ""
    data_files = [("Microsoft.VC90.CRT", glob.glob(r"C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86\Microsoft.VC90.CRT\*.*")),

Error it shows:

*** finding dlls needed ***
error: MSVCP90.dll: No such file or directory

But I've installed "Microsoft Visual C++ 2008 Redistributable Package". I'm running 32-bit python on 64-bit Windows 8. I'm trying to build a 32-bit binaries.

Also there is no folder like this: "C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\". This is what my computer contains:

EDIT:

On searching for msvcp90.dll on my C:\ drive I found that they are installed in weird paths like this:

I would recommend ignoring the dependency outright. Add MSVCP90.dll to the list of dll_excludes given as an option to py2exe. Users will have to install the Microsoft Visual C++ 2008 redistributable. An example:

setup(
    options = {
            "py2exe":{
            ...
            "dll_excludes": ["MSVCP90.dll", "HID.DLL", "w9xpopen.exe"],
            ...
        }
    },
    console = [{'script': 'program.py'}]
)

(new answer, since the other answer describes an alternate solution)

You can take the files from the WinSxS directory and copy them to the C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86\Microsoft.VC90.CRT directory (normally created by Visual Studio, which you don't have). Copy them to get the following structure:

  +-Microsoft.VC90.CRT
  | |
  | +-Microsoft.VC90.CRT.manifest
  | +-msvcm90.dll
  | +-msvcp90.dll
  | +-msvcr90.dll

Then, you should be able to run the setup program (still excluding msvcp90.dll, as in the other answer), and it should successfully find the files under Microsoft.VC90.CRT and copy them as data files to your bundle.

See the py2exe tutorial for more information.

I used to have a huge number of problems with complication on Windows, like the issue you're facing as well as installing packages like Cython with pip install cython.

The solution that worked best for me after two weeks of pain was downloading and running the unofficial MinGW GCC binary for Windows provided here. You might want to try giving that a shot and seeing if it helps.

If you do do it, you might want to uninstall MinGW if you have it already. I don't know if that's strictly necessary, but I always did it just in case. I did have it installed side-by-side with Cygwin without any problems.

I think it has something to do with the spaces in the directory. You should try using .rstrip(). For example, put this:

directory='C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86\Microsoft.VC90.CRT'
directory=directory.rstrip()

You can then use the variable directory like you would have used the actual path.

This should make python able to recognize the directory where it wouldn't be able to decipher it before.
