Cannot change existing environment variable

[mischajonker]

Once an environment variable already exists, we cannot override it anymore.

.env file:

TEST=foo

Script executed in runme.dev:

export TEST=bar
echo ${TEST}
export TEST_2=foo
export TEST_2=bar
echo ${TEST_2}

Expected result:

bar
bar

Actual result:

foo
bar

A similar situation happens when sourcing another script that sets environment variables. These environment variables can also not be overridden.
