我正在使用Angular 2，但没有使用useHash。
我发现无法直接在浏览器中访问该URL，这将返回404 not found。
我在Google上搜索了很多，并尝试了以下方法：
LocationStrategy添加PathLocationStrategy； loadChildren更改为相对路径。但是没有一个。
有人可以帮忙吗？谢谢。

如果我对它的理解不好。您需要在import sys
import re
import os
from collections import defaultdict
import nbformat
from nbconvert import LatexExporter, exporters
OUTPUT_FILES_DIR = './images'
CUSTOM_TEMPLATE = 'style_ipython_custom.tplx'
MAIN_TEX = 'main.tex'
def create_main():
# creates `main.tex` which only has macro definition
latex_exporter = LatexExporter()
book = nbformat.v4.new_notebook()
book.cells.append(
nbformat.v4.new_raw_cell(r'\input{__your_input__here.tex}'))
(body, _) = latex_exporter.from_notebook_node(book)
with open(MAIN_TEX, 'x') as fout:
fout.write(body)
print("created:", MAIN_TEX)
def init():
create_main()
latex_exporter = LatexExporter()
# copy `style_ipython.tplx` in `nbconvert.exporters` module to current directory,
# and modify it so that it does not contain macro definition
tmpl_path = os.path.join(
os.path.dirname(exporters.__file__),
latex_exporter.default_template_path)
src = os.path.join(tmpl_path, 'style_ipython.tplx')
target = CUSTOM_TEMPLATE
with open(src) as fsrc:
with open(target, 'w') as ftarget:
for line in fsrc:
# replace the line so than it does not contain macro definition
if line == "((*- extends 'base.tplx' -*))\n":
line = "((*- extends 'document_contents.tplx' -*))\n"
ftarget.write(line)
print("created:", CUSTOM_TEMPLATE)
def group_cells(note):
# scan the cell source for tag with regexp `^#latex:(.*)`
# if sames tags are found group it to same list
pattern = re.compile(r'^#latex:(.*?)$(\n?)', re.M)
group = defaultdict(list)
for num, cell in enumerate(note.cells):
m = pattern.search(cell.source)
if m:
tag = m.group(1).strip()
# remove the line which contains tag
cell.source = cell.source[:m.start(0)] + cell.source[m.end(0):]
group[tag].append(cell)
else:
print("tag not found in cell number {}. ignore".format(num + 1))
return group
def doit():
with open(sys.argv[1]) as f:
note = nbformat.read(f, as_version=4)
group = group_cells(note)
latex_exporter = LatexExporter()
# use the template which does not contain LaTex macro definition
latex_exporter.template_file = CUSTOM_TEMPLATE
try:
os.mkdir(OUTPUT_FILES_DIR)
except FileExistsError:
pass
for (tag, g) in group.items():
book = nbformat.v4.new_notebook()
book.cells.extend(g)
# unique_key will be prefix of image
(body, resources) = latex_exporter.from_notebook_node(
book,
resources={
'output_files_dir': OUTPUT_FILES_DIR,
'unique_key': tag
})
ofile = tag + '.tex'
with open(ofile, 'w') as fout:
fout.write(body)
print("created:", ofile)
# the image data which is embedded as base64 in notebook
# will be decoded and returned in `resources`, so write it to file
for filename, data in resources.get('outputs', {}).items():
with open(filename, 'wb') as fres:
fres.write(data)
print("created:", filename)
if len(sys.argv) <= 1:
print("USAGE: this_script [init|yourfile.ipynb]")
elif sys.argv[1] == "init":
init()
else:
doit()
文件中解决此问题。您可能只需要通过重定向到.htaccess来更新它。由于在Angular中，所有内容都在构建后位于index.html中。
index.html另外，必须像这样<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^(.*) index.html [NC,L]
</IfModule>
一样定义所有loadChildren:。因为更新的语法loadChildren: './path'会导致运行时编译器错误。
