无法针对未注册的加载器类型执行此操作 [英] can't perform this operation for unregistered loader type

问题描述

我正在使用bokeh进行数据可视化，并尝试制作可执行文件，但显示错误消息无法对未注册的加载器类型执行此操作"

I'm using bokeh for data visualization, and trying to make an executable but it shows an error message of "can't perform this operation for unregistered loader type"

我已尝试将 init .py解析为script.py的目录(+ subdir)，但这是行不通的.

I have tried as a solution of init.py to the directory (+subdir) of my script.py, but it's not work.

PS. Win10，Python 3.6.3，pyinstaller 3.4，bokeh 0.12.13

PS. Win10, Python 3.6.3, pyinstaller 3.4, bokeh 0.12.13

代码:

from bokeh.plotting import figure, show

p = figure(width=800, height=400, title="Money")
p.title.text_color = "green"
p.title.text_font_size = "18pt"
p.xaxis.axis_label = "Time"
p.xaxis.axis_label_text_color = "violet"
p.yaxis.axis_label = "Money"
p.yaxis.axis_label_text_color = "violet"
dashs = [12, 4]
listx1 = [1,5,7,9,13,16]
listy1 = [15,50,80,40,70,50]
p.line(listx1, listy1, line_width=4, line_color="red", line_alpha=0.3, line_dash=dashs, legend="Idle")

show(p)

推荐答案

使用pyinstaller遇到相同的错误.

Ran into the same error using pyinstaller.

这应该可以解决您的问题以及找不到随后出现的jinja2的问题:

This should solve your problem and the problem of not finding jinja2 that will follow:

编辑文件:your-python-env \ Lib \ site-packages \ bokeh \ core \ templates.py

edit the file: your-python-env\Lib\site-packages\bokeh\core\templates.py

(nb:将您的python-env更改为您安装python的位置)

(nb: change your-python-env to wherever you've installed python)

，然后从以下位置更改导入语句:

and change the import statements from:

import json

from jinja2 import Environment, PackageLoader, Markup

到以下:

import json
import sys, os
import bokeh.core    
from jinja2 import Environment, FileSystemLoader, Markup

下一步，找到显示以下内容的行:

Next, find the line where it says:

_env = Environment(loader=PackageLoader('bokeh.core', '_templates'))

将其注释掉并替换为以下代码:

comment this out and replace it with this code:

# _env = Environment(loader=PackageLoader('bokeh.core', '_templates'))

if getattr(sys, 'frozen', False):
        # we are running in a bundle        
        templatedir = sys._MEIPASS
else:
        # we are running in a normal Python environment
        templatedir = os.path.dirname(bokeh.core.__file__)

_env = Environment(loader=FileSystemLoader(templatedir + '\\_templates'))

(改编自: https://pythonhosted.org/PyInstaller/runtime-information.html )

这是因为冻结代码后，它将jinja2重定向到sys._MEIPASS(这是您的发行版所在的文件夹).具体来说，它将在sys._MEIPASS_templates查找jinja2模板.冻结后，文件指向错误的位置，因此是原始问题.

What this does is that when the code is frozen, it redirects the jinja2 looking to sys._MEIPASS (which is the folder where your distribution is). Specifically it looks for the jinja2 templates at sys._MEIPASS_templates. When frozen, the file points to the wrong location, hence the original problem.

所以现在，我们必须确保jinja2文件最终位于_templates文件夹中.为此，我们编辑pyinstaller .spec.这适用于编译到一个目录或一个文件.将.spec文件中的数据编辑为:

So now, we have to make sure the jinja2 files end up at the _templates folder. To do this we edit the pyinstaller .spec. This works for compiling to one directory or one file. Edit the datas in your .spec file to:

a = Analysis(['graphms-gui.py'],
             pathex=['C:\\Users\\choom.000\\Documents\\forcompile270218'],
             binaries=[],
             datas=[(r'your-python-env\Lib\site-packages\bokeh\core\_templates','_templates'),
                    ],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher)

它的作用是获取core_template文件夹的内容并将其复制到dist_templates.这正是我们指向templates.py查找jinja2文件的地方.

What this does is it gets the contents of the core_template folder and copies it to dist_templates. Which is exactly where we've pointed the templates.py to look for the jinja2 files.

这对我来说解决了pyinstaller == 3.3.1，bokeh == 0.12.9和jinja2 == 2.10的问题.

This resolved the problem for me with pyinstaller==3.3.1, bokeh==0.12.9 and jinja2==2.10.
