Pyinstaller Jinja2 TemplateNotFound

标签: python templates flask jinja2 pyinstaller

我正在使用pyinstaller构建我的烧瓶应用程序, 一切正常,但我遇到了Jinja2模板的问题。

它给了我jinja2.exceptions.TemplateNotFound

我尝试将from app import template放在模板文件夹中,但它不起作用(我猜因为它们不包含任何py文件)。

我还尝试更改.spec文件以包含templates文件夹

added_files = [
         ( '..\\CommerceApp\\app\\templates', 'templates' ),
         ( '..\\CommerceApp\\app\\static', 'static' )
        ]

a = Analysis(['..\\CommerceApp\\run.py'],
             pathex=['D:\\PythonProjects\\CommerceAppExe'],
             binaries=None,
             datas=added_files,
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher)

但它也不起作用,就像我自己手动复制文件夹一样。

有没有办法将模板与.exe捆绑在一起?

修改

这是我的spec文件

# -*- mode: python -*-

block_cipher = None

a = Analysis(['..\\CommerceApp_withPyInstaller\\run.py'],
             pathex=['D:\\PythonProjects\\CommerceAppExe'],
             binaries=None,
             datas=[],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          exclude_binaries=True,
          name='SupplyTracker',
          debug=False,
          strip=False,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=True,
               name='SupplyTracker')

修改2

已接受的答案已更改为gmas80,因为它解决了问题。

另外我只是意识到,我可以使用我的包名创建一个新文件夹,并填写静态模板csshtml等,它会起作用(类似于gmas80的结果)脚本确实)

我不相信这个问题是https://stackoverflow.com/a/35816876/2741329中描述的问题。我刚刚能够使用Jinja2冻结应用程序。

在我的spec文件中,我使用此方法收集所有模板:

from PyInstaller.building.build_main import Analysis, PYZ, EXE, COLLECT, BUNDLE, TOC


def collect_pkg_data(package, include_py_files=False, subdir=None):
    import os
    from PyInstaller.utils.hooks import get_package_paths, remove_prefix, PY_IGNORE_EXTENSIONS

    # Accept only strings as packages.
    if type(package) is not str:
        raise ValueError

    pkg_base, pkg_dir = get_package_paths(package)
    if subdir:
        pkg_dir = os.path.join(pkg_dir, subdir)
    # Walk through all file in the given package, looking for data files.
    data_toc = TOC()
    for dir_path, dir_names, files in os.walk(pkg_dir):
        for f in files:
            extension = os.path.splitext(f)[1]
            if include_py_files or (extension not in PY_IGNORE_EXTENSIONS):
                source_file = os.path.join(dir_path, f)
                dest_folder = remove_prefix(dir_path, os.path.dirname(pkg_base) + os.sep)
                dest_file = os.path.join(dest_folder, f)
                data_toc.append((dest_file, source_file, 'DATA'))

    return data_toc

pkg_data = collect_pkg_data('<YOUR LIB HERE>')

然后将pkg_data添加到COLLECT(1个文件夹)或EXE(1个文件).spec。

在1文件夹解决方案中,您应该能够在创建的子文件夹中找到所有模板。

这可能有用(假设您有一个包(即,您有__init__.py),请遵循以下建议:http://flask.pocoo.org/docs/0.10/patterns/packages/):

    from PyInstaller.utils.hooks import get_package_paths, remove_prefix, PY_IGNORE_EXTENSIONS

    # Accept only strings as packages.
    if type(package) is not str:
        raise ValueError

    pkg_base, pkg_dir = get_package_paths(package)
    if subdir:
        pkg_dir = os.path.join(pkg_dir, subdir)
    # Walk through all file in the given package, looking for data files.
    data_toc = TOC()
    for dir_path, dir_names, files in os.walk(pkg_dir):
        for f in files:
            extension = os.path.splitext(f)[1]
            if include_py_files or (extension not in PY_IGNORE_EXTENSIONS):
                source_file = os.path.join(dir_path, f)
                dest_folder = remove_prefix(dir_path, os.path.dirname(pkg_base) + os.sep)
                dest_file = os.path.join(dest_folder, f)
                data_toc.append((dest_file, source_file, 'DATA'))

    return data_toc

Jinja2包使用PyInstaller不支持的pkg_resources API。 pkg_resources模块通过setuptools包提供。

pkg_resources。这意味着   一个应用程序使用一个使用pkg_resources的库   API可能无法开箱即用。其中唯一的情况   它的工作原理是在.egg文件上使用它(见上文)。对于   详情请参阅问题#183。
