运行pyspark时没有此类文件或目录错误

Question

我安装了 spark 但是当我pyspark在终端上运行时，我得到了

/usr/local/Cellar/apache-spark/2.4.5_1/libexec/bin/pyspark: line 24: /Users/miguel/spark-2.3.0-bin-hadoop2.7/bin/load-spark-env.sh: No such file or directory
/usr/local/Cellar/apache-spark/2.4.5_1/libexec/bin/pyspark: line 77: /Users/miguel/spark-2.3.0-bin-hadoop2.7/bin/spark-submit: No such file or directory
/usr/local/Cellar/apache-spark/2.4.5_1/libexec/bin/pyspark: line 77: exec: /Users/miguel/spark-2.3.0-bin-hadoop2.7/bin/spark-submit: cannot execute: No such file or directory

我试过再次卸载和安装（spark、java、scala），但它一直抛出这个错误。也在这里和 GitHub 问题上搜索过，但找不到任何有用的东西。

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and which additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
  /Users/miguel/.pyenv/shims/python3.7-config
  /Users/miguel/.pyenv/shims/python3.7m-config

我在这方面花了很多时间，如果有人能指出解决方案，那就太好了。

原因是因为 SPARK_HOME 仍然设置为旧路径。即使source ~/.bash_profile这个值没有被取消，直到我申请：

unset SPARK_HOME

然后错误消失了。
