title: Google Cloud Composer taking too long to install dependencies
body: <p>I'm following the documentation for Google Cloud Composer to <a href="https://cloud.google.com/composer/docs/how-to/using/installing-python-dependencies#install-package" rel="nofollow noreferrer">install Python dependencies from PyPI</a> in an environment. I used this command to install the libraries from a requirements file:</p>
  <pre class="lang-sh prettyprint-override"><code>$ gcloud composer environments update $ENV_NAME \
      --update-pypi-packages-from-file requirements.txt \
      --location us-east4
  </code></pre>
  <p>It was just a test and this requirements file only has 4 libraries to install, but it takes more than 20 minutes to finish to execute this command. So I tried to use the user interface and install a single package from there, but it takes almost the same time.</p>
  <p>Something is not making sense to me, when I execute these commands the environment enters in a &quot;updating state&quot; and takes several minutes to be ready again. Why does Composer take so long to perform a <code>pip install</code>?</p>
  <p>Has anyone already faced a problem similar to that? How do you manage the installation of Python dependencies in Composer?</p>
