Pyinstaller 语法错误:异步函数中的“yield"(Python 3.5.1) [英] Pyinstaller Syntax error: 'yield' inside async function (Python 3.5.1)
问题描述
我正在尝试使用 pyinstaller
创建单个可执行文件以分发给未安装 Python 的用户.
I am trying to use pyinstaller
to create a single executable to distribute to users without Python installed.
该脚本非常简单,只是为了试水,我只使用了几行代码作为豚鼠".
The script is a very simple one and just to test waters I'm using just a few lines of code as "Guinea Pig".
Hello World
程序 - 没有导入,转换良好.
The Hello World
program - no imports, converts fine.
导入 matplotlib.pyplot
并绘制值列表的豚鼠程序失败了.
My Guinea Pig program, which imports matplotlib.pyplot
and plots a list of values, fails.
该问题是已知的并记录在此处,尽管他们声称已修复,或者也许我无法正确阅读.我认为修复应该在开发版本"中可用,应该是 3.2.1,我已经通过 pip install --upgrade pyinstaller
安装,但无济于事.
The issue is known and documented here, although they claim it is fixed, or maybe I can't read correctly.
I think the fix should be available in the "dev version" which should be 3.2.1, and I have installed through pip install --upgrade pyinstaller
, to no avail.
我不断收到相同的语法错误,这是在阅读
I keep getting the same syntax error, which occurs when reading the
module jinja2\asyncsupport.py
知道如何解决这个问题吗?我的项目非常简单,它只涉及matplotlib
、pandas
、读取文件和绘制一些数据.
Any idea how to work around this? My project is ultra simple and it just involves matplotlib
, pandas
, reading a file and plotting some data.
推荐答案
我遇到了同样的错误.
原因是 Jinja2 在 2.9 版本中为 Python3.6 添加了新的异步函数.
The reason is Jinja2 added new async function for Python3.6 in version 2.9.
请参阅http://jinja.pocoo.org/docs/2.9/changelog/#version-2-9-6
有两种方法可以避免此错误.这两个都对我有用.
There are two ways to avoid this error. Both of these worked for me.
降级 jinja2
Downgrade jinja2
# using Anaconda
conda install jinja2=2.8.1
# using pip
pip install jinja2==2.8.1
安装开发版的 PyInstaller
Install dev version of PyInstaller
# install from github
# Don't run "pip install -U pyinstaller" because the dev version is not released yet
pip install git+https://github.com/pyinstaller/pyinstaller.git
# check if "PyInstaller (3.3.dev0+g483dfde)" is in the list
pip list
