在我的本地开发环境中,我可以轻松运行 PySpark 应用程序,而无需配置任何内容。然而,在服务器上,我们使用 PyInstaller 进行 EXE 部署。 PyInstaller 在可执行文件中不包含 PySpark 库的
_internal
文件夹,因此我必须手动设置路径。
这是我的 PyInstaller
manage.py
脚本的片段:
# -*- mode: python ; coding: utf-8 -*-
# Analysis for manage.py
a_manage = Analysis(
['manage.py'],
pathex=['/app/app_name/app_name-backend-dev'],
# I tried adding .venv/lib/python3.11/site-packages to the pathex, but it didn't work
binaries=[
('/usr/lib/x86_64-linux-gnu/libpython3.11.so.1.0', './_internal/libpython3.11.so.1.0')
],
datas=[],
hiddenimports=[
# I tried adding pyspark imports, but it didn't work
'pyspark', 'pyspark.sql', 'pyspark.sql.session', 'pyspark.sql.functions', 'pyspark.sql.types', 'pyspark.sql.column',
'app_name2.apps', 'Crypto.Cipher', 'Crypto.Util.Padding', 'snakecase', 'cryptography.fernet',
'cryptography.hazmat.primitives', 'cryptography.hazmat.primitives.kdf.pbkdf2', 'apscheduler.triggers.cron',
'apscheduler.schedulers.background', 'apscheduler.events', 'oauth2_provider.contrib.rest_framework',
'app_name.apps', 'app_name.role_permissions', 'django_filters.rest_framework', 'app_name.urls',
'app_name.others.constants', 'app_name.models', 'app_name', 'sslserver'
],
hookspath=[],
hooksconfig={},
runtime_hooks=[],
excludes=[],
noarchive=False,
)
pyz_manage = PYZ(a_manage.pure)
exe_manage = EXE(
pyz_manage,
a_manage.scripts,
[],
exclude_binaries=True,
name='manage',
debug=False,
bootloader_ignore_signals=False,
strip=False,
upx=True,
console=True,
disable_windowed_traceback=False,
argv_emulation=False,
target_arch=None,
codesign_identity=None,
entitlements_file=None,
)
coll_manage = COLLECT(
exe_manage,
a_manage.binaries,
a_manage.datas,
strip=False,
upx=True,
upx_exclude=[],
name='manage',
)
当我尝试运行可执行文件时,遇到以下错误:
Traceback (most recent call last):
File "portal/operations/load_data/load_data.py", line 57, in start
File "portal/pyspark/operations.py", line 498, in get_session
File "pyspark/sql/session.py", line 497, in getOrCreate

FileNotFoundError: [Errno 2] No such file or directory: '/home/rhythmflow/Desktop/Reconciliation/reconciliation-backend-v3/dist/manage/_internal/./bin/spark-submit'
为了解决这个问题,我在 Linux 主目录中创建了一个全局
.venv
并使用 pip install pyspark
安装了 PySpark。
然后我手动设置
SPARK_HOME
环境变量:
SPARK_HOME = /home/user_name/.venv/lib/python3.11/site-packages/pyspark
并在我的代码中使用它,如下所示:
SPARK_HOME = env_var("SPARK_HOME")
SparkSession.builder.appName(app_name).config("spark.home", SPARK_HOME).getOrCreate()
这种方法在开发环境中工作得很好,但我想简化流程并避免手动指定Spark home路径。
有没有办法自动检测 PyInstaller 可执行文件中的 PySpark 主路径,这样我就不必手动设置
SPARK_HOME
环境变量?
如果您需要安装 pyspark 的目录,您应该能够执行如下操作:
import os
import pyspark
SPARK_HOME = os.path.dirname(pyspark.__file__)
