Brew Update Error: The following directories are not writable by your user:

Error: The following directories are not writable by your user:






You should change the ownership of these directories to your user.

To resolve try:

sudo chown -R $(whoami) /usr/local/include /usr/local/share/man/man3 /usr/local/share/man/man5 /usr/local/share/man/man7 /usr/local/share/man/man8

If that fails, just reinstall brew by going to https://brew.sh/

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Swagger Codegen for PHP

First install Java 7 or 8

1 - Set environment variables for java

export JAVA_HOME=$(/usr/libexec/java_home)
export JAVA_HOME=`/usr/libexec/java_home -v 1.8`

export PATH=${JAVA_HOME}/bin:$PATH

2 - Clone the REPO 

$ git clone https://github.com/swagger-api/swagger-codegen.git

3 - Switch into the directory 

$ cd swagger-codegen

3 - Build the project form code using maven.  Direction for maven on other post.

$ mvn clean package

4 - Generate the client for your endpoint

Replace the below item in < > with your custom values.

java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
   -i ../acumatica_client/swagger/swagger_customerschema_17.200.001.json \
   -l php \
   --invoker-package "<RootNamespace>\<CustomNamespace>" \
   --git-user-id "<yourgithubuserid>" \
   --git-repo-id "<yourgithubrepo>" \
   -o ~/Source/Repos/<my_output_folder>

5.  Switch to the output folder from above <my_output_folder>

cd ~/Source/Repos/<my_output_folder>

6.  Make git_push executable so we can push to source control.

chmod +x git_push.sh

7.  Push to source control.


7a - git pull origin master --allow-unrelated-histories

8 - Open the newly generated README.md file, copy the text from the Installation & Usage, Composer.json section 


9 - Open your PHP client project that you want to use the swagger generated code in and paste the previously copied text from README.md

  "repositories": [
      "type": "git",
      "url": "https://github.com/<yourgithubuserid>/<yourgithubrepo>.git"
  "require": {
    "<yourgithubuserid>/<yourgithubrepo>": "*@dev"

11 - Run Composer Install from the PHP Client project to install references

$ composer install

Note you may need to run 

$ composer update --lock

Add a generic called runme.php file and add code from README.md

} catch (Exception $e) {
    echo 'Exception when calling CategorySchemaApi->categorySchemaDeleteById: ', $e->getMessage(), PHP_EOL;


and run it
$ php runme.php

Mac: Install Maven Command Line

Mac:  Install Maven Command Line

Download Apache Maven (MVN) from


You should download the binary (Targ.gz or zip) and not source

After you have downloaded it, unzip it by double clicking it or unzip by terminal command (example:)

$ unzip apache-maven-3.6.0-bin.zip

Open terminal if you haven't already and go to the download directory.  We'll move the expanded download file to a new location.

$ cd ~/Downloads

$ mv apache-maven-3.6.0-bin /usr/local/bin/maven

Let's add a maven/bin folder to the path

$ nano .bash_profile

Add the line and save it (control + x)

export PATH=/usr/local/bin/maven/bin:$PATH

Close terminal and reopen

Verify you can access mvn

$ mvn --version



Open Terminal

$ nano ~/.bash_profile

Add the following line:

export JAVA_HOME=$(/usr/libexec/java_home)

Close terminal and reopen

Mac Mongodb Installation

Download MongoDB community server


Unzip the file in downloads

mongodb-osx-ssl-x86_64-4.0.4.tgz  => mongodb-osx-ssl-x86_64-4.0.4

Copy the file to the bin directory.  Open Terminal

cd mongodb-osx-ssl-x86_64-4.0.4
cd bin
mkdir /usr/local/bin/mongodb
cp * /usr/local/bin/mongodb
sudo mkdir -p /data/db
sudo chmod 777 /data
sudo chmod 777 /data/db

Add the MondgoDB file path to .bash_profile

$ nano ~/.bash_profile

Add the following line to .bash_profile and save:

   export PATH=/usr/local/bin/mongodb:$PATH
You'll probably need to restart the terminal session for path to be applied.

Start MongoDB by typeing mongod (d is for daemon)

$ mongod

Open a new terminal window and switch to the directory, type mongo

$ mongo

Insert a test record

> db.users.insert({"fullname": "robert amiscaray"})

Install Python 3 by doing brew install python.  Note:  PIP3 will also be installed.

$ brew install python

Install httpie for http helpers

$ sudo -H pip3 install httpie
