运行pyspark时没有这样的文件或目录错误

我安装了 Spark，但是当我运行时pyspark在终端上，我得到

/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

我尝试卸载并再次安装（spark、java、scala），但它一直抛出此错误。还在这里和 GitHub 问题上进行了搜索，但找不到任何有效的东西。

附加信息：

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
  /Users/miguel/.pyenv/shims/python-config

我在这方面花了相当多的时间，如果有人能指出解决方案那就太好了。

原因是 SPARK_HOME 仍然设置为旧路径。 即使source ~/.bash_profile在我应用之前，该值没有被取消设置：

unset SPARK_HOME

然后错误就消失了。
