<pre>pip_import(<a href="#pip_import.name">name</a>, <a href="#pip_import.requirements">requirements</a>)</pre>
<p>A rule for importing <code>requirements.txt</code> dependencies into Bazel.</p>
<p>This rule imports a <code>requirements.txt</code> file and generates a new
<code>requirements.bzl</code> file. This is used via the <code>WORKSPACE</code>
pattern:</p>
<pre><code>pip_import(
name = "foo",
requirements = ":requirements.txt",
)
load("@foo//:requirements.bzl", "pip_install")
pip_install()
</code></pre><p>You can then reference imported dependencies from your <code>BUILD</code>
file with:</p>
<pre><code>load("@foo//:requirements.bzl", "requirement")
py_library(
name = "bar",
...
deps = [
"//my/other:dep",
requirement("futures"),
requirement("mock"),
],
)
</code></pre><p>Or alternatively:</p>
<pre><code>load("@foo//:requirements.bzl", "all_requirements")
py_binary(
name = "baz",
...
deps = [
":foo",
] + all_requirements,
)
</code></pre>
